This application claims priority to U.S. Provisional Patent Application No. 61/708,786, entitled “Dental Device,” filed October 2, 2012. This application is incorporated herein by reference in its entirety.

Field of the Invention

The present technology relates to dental devices suitable for interdental cleaning and for delivering dentally-active materials.

Background of the Invention

The area between the teeth, known as the interdental area, is most susceptible to plaque accumulation, periodontal damage, and caries because it is the most difficult area of the mouth to clean.

Specifically, the interdental area refers to the proximal area, which is the area between adjacent teeth consisting of tooth roots covered by cementum, which is located on the surface of dentin and may also contain enamel covering the cementum from the gingival crown to the contact area, which is the area where adjacent teeth contact each other (i.e., dentin, enamel, cementum, gums, subgingival sulcus, periodontal pockets, etc.). Cementum is often eroded or worn away, exposing the soft and vulnerable enamel surface underneath, causing hypersensitivity reactions or caries. This is also the area most susceptible to plaque accumulation and periodontal damage.

Most devices designed to clean this interdental area require manual dexterity, are difficult to use, time-consuming, painful, ineffective, prone to wear or breakage, and/or expensive, making them less desirable for patients. Dental floss is difficult to use and, especially when a certain degree of periodontal damage has occurred, is not adequate for cleaning the interdental area. Currently, most interdental devices are brushes, which are typically made of nylon bristles inserted into a twisted wire rod. These brushes are brittle and often break. The nylon wire can also scratch and irritate delicate root surfaces, as well as dental restorations and implants. They are typically too wide to fit comfortably between the teeth. Other interdental cleaning devices are shaped like wedges, requiring only a push/pull technique for cleaning and often leaving behind plaque and debris.

These devices are also limited by their inability to deliver active dental materials, such as medications, antiseptics, fluoride, recalcification products, varnishes, whitening products, etc., to the interdental area. While some existing products can be used to carry or deliver such substances, most remove them from the interdental space upon device withdrawal. Furthermore, most existing products are designed for manual use and do not offer the added advantages of ease and effectiveness of use found in electric, sonic or ultrasonic, or manual dental devices.

One device previously proposed by the inventors of this technology to improve this area is the device described in U.S. Patent No. 7,806,125, entitled "Interdental Cleaner and Delivery Device," issued on October 5, 2010, which is incorporated herein by reference in its entirety. While this device is undoubtedly adequate for its intended purpose, improvements are possible.

Summary of the Invention

To this end, one object of the present technology is to propose an improvement in interdental area cleaning devices.

To this end, in one aspect, an embodiment of the present technology is to provide a dental device comprising: a handle; a stem having a stem tip, which in turn has an end, the stem tip having a first groove wrapped around it, the groove extending from a first distal point near the end toward the handle around the stem tip at least one full circle, extending to a termination point of the first groove (for example, similar to a drill bit groove); the stem having a first flange extending outward and wrapped around it (for example, similar to a screw thread), the first flange extending away from the handle from a first proximal point toward the end of the stem tip, extending to a termination point of the first flange; at least a portion of the stem having a first groove, at least a portion of the first flange being suitable for insertion into an area between two teeth; thereby, the interdental area can be cleaned by inserting at least a portion of the stem between the teeth.

The size of the stem of the device is required so that at least the tip of the stem (and possibly more of the stem) can be inserted into the interdental area between two adjacent teeth for cleaning. Depending on the intended use of the device, different embodiments will use stems (including the tip of the stem) of different shapes and sizes. Depending on the size and shape of the stem, the layout of the grooves and flanges on the stem, and the size and shape of the interdental area into which the stem is inserted, at least one of the grooves and flanges will be within the interdental area and will contact the teeth together with the outer surface of the stem. (In most embodiments, the tip of the stem is solid and small/narrow enough to fit within the smallest interdental area). The area where the teeth contact the stem can be partially cleaned due to the mechanical contact action. To this end, according to one aspect of cleaning, the stem can be repeatedly removed and reinserted into the interdental area. (Insert the stem between the interdental area and then push between the teeth until resistance is felt). As the rod is inserted into the interdental area, foreign matter (tooth debris, plaque, etc.) in the interdental area can be pushed out to the lingual side of the teeth, or these materials can be trapped in the grooves and/or valleys formed by the successive turns of the device flange and can be removed from the interdental area when the rod is withdrawn.

Once inserted, the shaft can be rotated (manually or mechanically). In this regard, the grooves and flanges are structurally arranged on the shaft (particularly by wrapping around it) to further assist in cleaning the interdental area. Depending on the handedness of the grooves and/or flanges on the shaft, as well as the size and shape of the shaft/tip, when the shaft is rotated in one direction, this rotation can help the shaft penetrate deeper into the interdental area because the grooves can grip the teeth (screw-like). This rotation can also assist in removing foreign matter from the interdental area, similar to how the grooves of a drill bit remove material (e.g., shavings) as the drill bit drills through it. (For right-hand wrapping, the shaft can be rotated clockwise to accomplish this function. For left-hand wrapping, the shaft can be rotated counterclockwise to accomplish this function.) Foreign matter can be moved upward (toward the handle) within the grooves and/or valleys formed between successive turns of the flange, thereby being carried out of the interdental area for removal. In some cases, this can be more effective in removing foreign matter from the interdental area than simply removing and reinserting the stem. Alternatively, when the stem is rotated in the opposite direction, this rotation can also assist in removing foreign matter from the interdental area by trapping it in the grooves and/or valleys formed by the continuous rotation of the flange, and transporting it through the interdental area to the lingual side of the teeth. (For right-hand wrapping, the stem rotates counterclockwise to accomplish this. For left-hand wrapping, the stem rotates clockwise to accomplish this.)

Additionally, rotation in either direction can aid in cleaning the interdental area by frictionally contacting the teeth. Rotation of the stem is not limited to fully inserting the stem between the teeth. The stem can also be rotated while inserting and/or withdrawing the stem from between the teeth, further assisting in cleaning.

In some embodiments, both the flange and the groove have a helical or spiral or modified helical arrangement and structure. The longitudinal, horizontal, and beveled configurations of the helical portions of the flange and groove provide for cleaning and material delivery in the interdental area, particularly when the device is rotated, vibrated, and flushed, or any combination thereof. This configuration also facilitates removal from the mold during the manufacturing process.

In some embodiments, the device can be easily attached to other devices. The device can be operated manually, as it can be rotated by hand, or moved in and out by finger movements on a handle or handle extension (the handle can be attached to the device cover), or by mechanical means. The rod can be inserted into an acoustic or ultrasonic device and vibrated. The rod consists of flanges and grooves arranged in horizontal, oblique, and vertical configurations (this arrangement also allows for easy and unobstructed ejection from the mold), allowing for cleaning and removal of substances and medications while vibrating. The vibrating action is transmitted to the flanges and grooves of the device so that when the device is inserted into the interdental space, the increased action and friction allow the space to be better cleaned, even when the device is stationary, preferably when it is rotated or inserted and removed. In addition, by using vibration after being connected to an acoustic or ultrasonic device, medication can be very effectively delivered to the interdental space, just as a dog shakes water off its fur by shaking back and forth. The device is easy to connect to sonic and ultrasonic devices, transmits vibrations, improves drug delivery and penetration depth in the groove, and particularly in the interdental area, delivers the drug to the teeth, gums and periodontal tissues. In addition, the device can also be easily fixed to a flushing device, and when the device is used for cleaning and drug delivery, substances and drugs can be pumped onto the device. It can be easily fixed to a rotating, vibrating and flushing device, or any combination of all of these devices. The device can be easily fixed to an ordinary manual toothbrush, preferably a handle, (making it convenient to use the same device for brushing and interdental cleaning). When the device is fixed to the back or belly of the handle, the device is preferably used in an in-and-out manner. When the device is fixed to the end of a manual toothbrush, the device can be easily rotated as the toothbrush rotates, or it can also be used in an in-and-out manner.

The grooves/flanges of the stem can also serve a secondary purpose: facilitating the delivery of active dental material to the interdental area. For example, when the stem is immersed in a fluidic active dental material, this material can be entrained within the grooves and/or valleys between the successive flanges of the stem (in addition to being coated on the stem's outer surface). Once the stem is inserted into the interdental area, this material can be displaced and/or rubbed against the stem at the contact area and delivered to the interdental area. Furthermore, and still depending on the winding direction of the grooves and/or flanges, rotating the stem in the opposite direction (i.e., counterclockwise for right-hand winding and clockwise for left-hand winding) can alter the direction of movement of the material within the grooves and/or valleys formed between the successive turns of the flanges. Therefore, when the stem is inserted into the interdental area and rotated in the opposite direction to the aforementioned "drill-like" foreign body removal, the active dental material within the grooves and/or valleys formed between the successive turns of the flanges can be displaced and delivered there. A significant portion of the delivered material remains in the interdental area after the device is removed. To this end, the interdental area can be simultaneously cleaned (by abrasion), and medications can also be delivered in this manner (e.g., fluoridation by delivering a fluoride substance). (For the purposes of this specification, tooth-active materials may include, but are not limited to, medications, antibiotics, antiseptics, wear-resistant materials, antimicrobial agents, whitening agents, desensitizing agents, demineralizing agents, remineralizing agents, varnishes, fluoride, toothpaste, dental paste, tooth gel, and dental solutions (e.g., remineralizing pastes)).

The stem may be made of any suitable tooth-compatible material. For example, such materials include plastics, such as regular or high-density polyethylene, polypropylene, polycarbonate, etc.; wood; rubber; latex; silicone; or related or derived substances. The stem need not be made from a single or uniform material. Any suitable combination of suitable materials is possible. The stem may be manufactured using a device that is compatible with the material from which it is made. The mechanical properties of the stem, such as rigidity, flexibility, compressibility, elasticity, etc., may vary between different embodiments. The only requirement regarding any such mechanical properties is that the stem must be suitable for its intended use as described herein.

In some embodiments of the technology, the first groove terminates at the same point as the first flange. For this purpose, the first groove is connected to the first flange. (Similarly, in embodiments having more than one groove and/or flange, additional grooves may terminate at the same point as additional flanges.) In some embodiments, without wishing to be bound by any particular concept, this arrangement appears to facilitate transport of substances through the grooves and/or flanges, particularly from the grooves to the flanges and vice versa.

In some embodiments of the present technology, the termination point of the first groove and the termination point of the first flange are radially offset from each other. As a result, the termination points of the first groove and the first flange appear to be "twisted" around the device stem. In embodiments where more than one groove and/or flange is present, the termination points of the other grooves may be radially offset from the termination points of the other flanges in the same manner.

In some embodiments of the technology, the first groove terminates at a point axially offset from the first flange. In some such embodiments, the first groove terminates closer to the end of the shaft tip than the first flange terminates. In these embodiments, the two points are longitudinally spaced apart from each other on the shaft; thus, a longitudinal gap exists between them. In other such embodiments, the first groove terminates further from the end of the shaft tip than the first flange terminates; thus, the first groove and the first flange are "intertwined" over a portion of each other. In some such embodiments, the first groove extends within a portion of the valley formed between successive turns of the first flange. In some embodiments, this facilitates the delivery of substances through the groove and flange, and in particular, the delivery of substances from the groove into the valley formed between successive turns of the flange, and vice versa. In embodiments where there is more than one groove and/or flange, the termination points of the additional grooves may be axially offset from the termination points of the additional flanges in the same manner.

It should be clear that in some embodiments, the first groove end point and the first flange end point may be radially and axially offset from each other. In embodiments where there is more than one groove and/or flange, the end points of the other grooves may be radially offset from the end points of the other flanges in the same manner.

In some embodiments, the first groove is continuous with the valley formed between successive turns of the first flange. In this regard, the first groove terminates at the same point on the shaft as the valley formed between successive turns of the first flange. Furthermore, depending on the embodiment and the material involved, this can facilitate the transfer of materials through the grooves and flanges, in particular, transferring materials from the grooves to the flanges and vice versa. In embodiments where more than one groove and/or flange is present, additional grooves are continuous with additional valleys formed between successive turns of additional flanges.

In some embodiments, the first groove and the first flange are of the same handedness. In some such embodiments, the first groove and the first flange are both left-handed. In some such embodiments, the first groove and the first flange are both right-handed. In any particular embodiment, the specific handedness depends on whether the device is used by a right-handed person or a left-handed person. Without wishing to be bound by any particular philosophy, it is contemplated that a right-handed person would prefer to use a device with a right-handed groove and flange. In embodiments where there is more than one groove and/or flange, each groove and flange can be of the same handedness.

However, in some embodiments, the handedness of the first groove and the first flange are opposite to each other. In some such embodiments, the first groove is left-handed and the first flange is right-handed. In some such embodiments, the first groove is right-handed and the first flange is left-handed. According to such embodiments, for example, such an arrangement can be used such that the groove assists in removing foreign matter from the interdental area and the flange assists in delivering tooth active material to the interdental area, or vice versa. In embodiments where there is more than one groove and/or flange, the handedness of each groove can be opposite to the handedness of each flange.

In some embodiments, the first groove has a uniform depth, thickness, and shape. In some embodiments, the first groove has at least one of a non-uniform depth, a non-uniform thickness, and a non-uniform shape. There are no specific requirements for the depth, thickness, and shape of the groove. The groove can be of any thickness, depth, or shape, as long as the groove performs the intended function described herein. In embodiments having multiple grooves, the groove can have a uniform thickness, depth, and shape, or at least one of a non-uniform depth, non-uniform thickness, and non-uniform shape.

In some embodiments, the first flange is of uniform thickness. In some embodiments, the first flange is of variable thickness. A specific flange thickness is not required. The flange can be of any thickness, provided it performs the intended function described herein. In embodiments having multiple flanges, the flanges can be of uniform thickness and length, or of non-uniform thickness and/or length.

In some embodiments, the first flange tapers toward the end of the shaft tip. To this end, in some such embodiments, the distance the flange extends away from the shaft portion decreases as the flange moves toward the end of the shaft tip. In this case, the flange is not required to taper at a uniform rate. The flange can taper uniformly or non-uniformly. In embodiments having multiple flanges, the flanges can taper uniformly or non-uniformly. Furthermore, some flanges can taper while others do not.

In some embodiments, the first flange extends uniformly from the stem. To this end, in some such embodiments, the distance the flange extends away from the stem is constant. In embodiments having multiple flanges, each flange may extend uniformly from the stem, at least one flange may extend uniformly from the stem, or none of the flanges may extend uniformly from the stem.

In some embodiments, the cross section of the shaft is one of circular, triangular or square. In some such embodiments, the cross section of the shaft is one of circular, triangular or square throughout. In some such embodiments, the cross section of the shaft is more than one of circular, triangular or square.

In some embodiments, at least a portion of the shaft tapers toward the end of the shaft tip. In some such embodiments, the taper is uniform. In some such embodiments, the taper can be non-uniform.

In some embodiments, the cross-section of the rod tip is one of circular, triangular, or square. In some such embodiments, the cross-section of the rod tip is the same as the cross-section of the remainder of the rod. In some such embodiments, the cross-section of the rod tip is different from the cross-section of the remainder of the rod. In some such embodiments, the cross-section of the rod tip is more than one of circular, triangular, or square.

In some embodiments, at least a portion of the rod tip tapers toward the end of the rod tip. In some such embodiments, the taper is uniform. In some such embodiments, the taper is non-uniform.

In some embodiments, the cross-section of the rod tip is uniform.

In some embodiments, the first groove is helical. In embodiments having more than one groove, each groove is helical. For example, in embodiments having two grooves, each groove is helical forming a double helix. In some embodiments, the first groove (while still wrapped around the shaft) does not form a complete helix. In embodiments having more than one groove, none of the grooves form a complete helix. In some embodiments, the first groove can be a perfect helix. In embodiments having more than one groove, each groove can be a perfect helix.

In some embodiments, the first groove has a series of linear portions interconnected by a series of curved portions. In some such embodiments, the corresponding linear portions of each turn of the first groove are parallel. In some such embodiments, each turn of the first groove has four distinct linear portions. In embodiments having multiple grooves, each groove has the above-described characteristics. Depending on the embodiment and the method of manufacturing the rod, having the structure described in this paragraph can simplify the production of the rod. For example, such a structure can make it easier and/or simpler to remove the rod from the mold.

In some embodiments, the first flange is helical. In embodiments with more than one flange, each flange is helical. For example, in embodiments with two flanges, each flange is helical forming a double helix. In some embodiments, the first flange (while still wrapped around the stem) does not form a complete helix. In embodiments with more than one flange, none of the flanges can form a complete helix. In some embodiments, the first flange can be a perfect helix. In embodiments with more than one flange, each flange can be a perfect helix.

In some embodiments, the first flange has a series of planar portions interconnected by a series of curved portions. In some such embodiments, the corresponding planar portions of each turn of the first flange are parallel. In some such embodiments, each turn of the first flange has four distinct planar portions. In embodiments having multiple flanges, each flange has the above-described characteristics. Depending on the embodiment and the method of manufacturing the rod, having the structure described in this paragraph can simplify the manufacture of the rod. For example, such a structure can make it easier and/or simpler to remove the rod from the mold.

In some embodiments, the first groove is continuous, so that the first groove will not be broken or discontinuous due to the first groove being wrapped around the rod.

In some embodiments, the first groove is discontinuous. Thus, the first groove may have at least one (or even several) breaks or discontinuities due to the first groove wrapping around the shaft. There are no particular requirements for the form or manner of the structure of these breaks or discontinuities. Where multiple such breaks or discontinuities occur, they do not need to be identical.

In embodiments with multiple grooves, the consistency/discontinuity is not required to be the same between grooves.

In some embodiments, the first flange is continuous, so that the first flange does not become disconnected or discontinuous as the first flange is wrapped around the stem.

In some embodiments, the first flange is discontinuous. To this end, the first flange may have at least one (or even several) breaks or discontinuities due to the first flange being wrapped around the stem. There is no particular requirement for the form or manner in which such breaks or discontinuities are structured. Where multiple such breaks or discontinuities occur, they do not need to be identical. As non-limiting examples, such breaks or discontinuities may be in the form of notches, grooves, recesses, indentations, or the like.

In embodiments with multiple flanges, the continuity/discontinuity is not required to be the same between grooves.

In some embodiments, the dental device further includes at least one channel extending longitudinally along the outer surface of the shaft, at least partially passing through the discontinuity between at least one of the first flanges and the first groove. Depending on the embodiment, for example, this longitudinally extending channel facilitates the delivery of liquid to the interdental space. For example, this liquid may include the aforementioned tooth-active material, or water. In some such embodiments, the shaft has at least one opening located adjacent to the at least one channel, and the shaft has a hollow portion fluidically connected to the at least one opening, such that liquid can flow through the hollow portion, through the at least one opening, and into the at least one channel. In some embodiments, the liquid can be stored within the shaft and/or the handle. In some embodiments, the liquid can be stored in a reservoir connected to the handle. In some such embodiments, the liquid can be released and forced to flow by applying positive pressure to the reservoir. In some such embodiments, the liquid can be forced into the reservoir through the opening by negative pressure within the reservoir (for injection into the reservoir for later use) (e.g., similar to eye drops). In some embodiments, there are multiple such channels, each having any of the aforementioned characteristics. In some such embodiments, a pump can be used to pump the liquid from the reservoir.

In some embodiments, the outside of the rod has a plurality of openings and at least one hollow portion connected to the plurality of openings by a fluid, so that liquid can flow through the hollow portion via the plurality of openings. In some embodiments, among the plurality of openings, at least a portion of the openings are located in the valleys between the continuous turns of the flange. (As described above, if the liquid flows into the grooves and/or valleys, and the portion of the rod where these grooves and/or valleys are located is not yet located in the interdental area, the rotation of the rod will cause the fluid to flow from its current position through the grooves and/or valleys into the interdental area so as to deliver the medicine thereto). In some embodiments, the liquid is stored in the rod and/or the handle. In some embodiments, the liquid can be stored in a reservoir connected to the handle. In some such embodiments, the liquid can be released and forced to flow by applying a positive pressure to the reservoir. In some such embodiments, the liquid can enter the reservoir through the opening via the negative pressure in the reservoir (so as to be injected into the reservoir for later use) (for example, similar to eye drops). In some such embodiments, the liquid can be pumped out of the reservoir using a pump.

In some embodiments, the dental device further includes at least one channel located within the valley formed between successive turns of the first flange. Depending on the embodiment, this channel can be used to increase the volume of the valley formed between successive turns of the first flange, thereby enhancing the valley's ability to facilitate the transport of the aforementioned substance. In some embodiments, multiple such channels are used.

In some embodiments, at least a portion of the stem is at least one of coated and infused with a tooth-active material. In this regard, rather than immersing the stem in the tooth-active material, the tooth-active material is placed within or on the stem itself. For example, such a coating or infusion material may already be applied when the stem is manufactured. In some embodiments, such a tooth-active material may be used as a catalyst or combined in some way with another substance that may be present in the oral cavity, such as, but not limited to, saliva, bacteria, biofilm, water, leftover mouthwash, toothpaste, or any other medication, paste, gel, etc., carried into the oral cavity to activate or be activated, thereby performing a therapeutic, cleaning, or whitening or other function.

Additionally, it should be appreciated that a portion of the stem (including the flange and/or groove) may have a dentally active material sprayed thereon (in addition to or in lieu of such a coating or infusion).

In some embodiments, the rod has at least one radial groove for bending the rod. In some embodiments, the rod has multiple such radial grooves. When the rod rotates, the radial grooves can cause the rod to bend continuously, so that the rod stays in its intended position and/or location and is not affected by such rotation. Between different embodiments, the various physical properties of such radial grooves (for example, shape, size, location, etc.) will be different. There are no specific requirements for these physical properties. Any physical properties that enable the groove to perform its intended function are acceptable. In the case of multiple such radial grooves, these physical properties do not need to be the same for any or all of the radial grooves. No further requirements are made regarding the specific order and arrangement of the multiple grooves.

As mentioned above, the shaft is not limited to having only one groove and one flange. The technology also includes shafts having multiple grooves and/or multiple flanges. In this case, the number of grooves and flanges is not necessarily the same. In some embodiments, the number is equal, but in other cases, there may be more grooves and in other cases, there may be more flanges. To this end, in some embodiments, the tip of the shaft has a second groove that wraps around the tip of the shaft at least one complete turn from a second distal point near the end toward the handle to a second groove termination point, the second groove being offset from and intertwined with the first groove; and the shaft has a second flange that extends outward from the shaft and wraps around the shaft, the second flange extending away from the handle from a second proximal point toward the end of the tip of the shaft to a second flange termination point, the second flange being offset from and intertwined with the first flange.

It should be noted that the characteristics described above for the first groove and/or first flange may also be applied (mutatis mutandis) to the second (or additional) groove and/or second (or additional) flange.

In some embodiments, the dental device further includes a plurality of bristles extending radially outward from the periphery of the rod to the end of the rod tip. For example, these bristles can assist in cleaning teeth. The ends of the bristles form an outer dentally-active edge, similar to the cleaning surface of a conventional toothbrush. In some such embodiments, the more outward dentally-active edge is formed by the bristles. In some such embodiments, the bristles form an outer dentally-active edge that is inclined outward. In some such embodiments, the bristles form an outer dentally-active edge that is inclined inward. In some embodiments, the slope of the outer edge can be different depending on the function of the outer edge, that is, which teeth it is desired to assist in cleaning.

In some embodiments, the dental device further includes a domed cup extending radially outward from the shaft and toward the tip of the shaft to assist in cleaning teeth. The cup is relatively flexible and can be made of conventional dental-compatible materials such as rubber, silicone, or plastic. The cup can have additional features to assist in cleaning teeth, such as reinforcing ribs, ridges, or a wear-resistant surface.

In some embodiments, the handle has a securing mechanism for releasably attaching the dental device to a mechanical device (e.g., a motor, pump, sonic or ultrasonic device) or a manual device (e.g., a hand tool, a toothbrush, etc.). Depending on the embodiment, any number of conventional connection and securing mechanisms may be suitable. Such mechanisms include friction fit devices, mechanical locking or interlocking devices, mechanical fasteners, and the like.

In some embodiments, the device further comprises a cover sized to releasably cover the stem when the device is not in use. In some such embodiments, the cover is releasably connected to a handle of the device. In some such embodiments, the cover can serve as a reservoir for the tooth active material, e.g., into which the stem can be immersed. In some such embodiments, the cover can have a valve (e.g., a one-way valve) for filling the reservoir with the tooth active material.

In another aspect, embodiments of the technology include a method of cleaning the area between teeth, the method comprising inserting at least a portion of a stem of a dental device described above between the teeth, and rotating the device stem.

According to the present specification, the words "first", "second", etc. are used as adjectives to distinguish the nouns they modify from each other, and do not indicate any specific relationship between these nouns. For example, it should be understood that the use of the terms "first groove" and "second groove" does not indicate any specific order, type, sequence, hierarchy, or ranking (for example) of/between the grooves.

Implementations of this technology all include at least one of the above-mentioned objectives and/or aspects, but not necessarily all of them. It should be understood that some aspects of this technology are formed in an attempt to achieve the above-mentioned objectives and may not meet such objectives and/or may meet other objectives not specifically listed herein.

Additional and/or other features, aspects, and advantages of embodiments of the technology will become apparent from the following description, drawings, and appended claims.

Detailed Description of the Invention

Various dental devices 10, 110, 210, etc. are shown in all figures. It should be understood that the various dental devices 10, 110, 210, etc. are merely some embodiments of the present technology. Therefore, the following description is merely illustrative of the present technology. This description does not define the scope of the present technology or suggest its limits. In some cases, examples of modifications believed to be helpful for understanding the present technology are also described below. This is done solely for the purpose of understanding the present technology and does not define the scope of the present technology or suggest its limits. These modifications are not intended to be comprehensive, and, as will be appreciated by those skilled in the art, other modifications are possible. Furthermore, where modifications have not been made (i.e., examples have not been provided), it should not be construed that modifications are not possible and/or that these are the only ways to implement a particular portion of the present technology. As will be appreciated by those skilled in the art, this may not be the case. Furthermore, it should be understood that in some cases, the dental devices 10, 110, 210 may provide a simplified embodiment of the present technology, and, in such cases, these examples are provided to facilitate understanding. Those skilled in the art will appreciate that various implementations of this technology are not overly complex.

FIG1 shows a dental device 10, a first embodiment of this technology. The dental device 10 comprises a handle 12 and a shaft 14 extending therefrom. The shaft 14 has a tip 16. In this embodiment, the handle 12, shaft 14, and tip 16 are integrally formed of plastic using an injection molding process. In this embodiment, the handle 12, shaft 14, and tip 16 taper gradually from an end 18 of the handle 12 to an end 20 of the tip 16. The tip 16 is solid and sized to fit within the interproximal space between two adjacent teeth. The shaft 14 has an outwardly extending and wrapping flange 22. The flange 22 extends away from the handle 12 from a proximal point 24 to a flange termination point 26. The flange 22 is in the form of a continuous left-hand helix. Between the turns of the flange 22 are openings 28, which provide fluid communication with a cavity (not shown) in the handle 12, allowing liquid to enter the valley 30 formed between successive turns of the flange 22.

The shaft tip 16 has a groove 32 formed therein and wound around it. The groove 32 extends from a distal point 34 near the end 20 of the shaft tip 16 toward the handle 12 to a groove termination point 36. In this embodiment, the groove termination point 36 is axially offset from the flange termination point 26, with the groove termination point 36 being closer to the end 20 of the shaft tip 16 than the flange termination point 26. As a result, an axial "gap" 38 exists between the groove termination point 36 and the flange termination point 26. The groove is in the form of a continuous left-hand helix.

The end 18 of handle 12 has a connecting mechanism (not shown) that releasably connects the dental device to the electric device. In addition, the handle is large enough to be held and rotated.

The dental device 10 can be used to clean the interdental area between two adjacent teeth, as described above. For example, the tip 16 of the stem 14 can be inserted into the interdental area and pushed until resistance is felt. Depending on the size and shape of the interdental area into which the stem 14 is inserted, at least one of the grooves 32 and flanges 22 will be present in the interdental area and, along with the outer surface 40 of the stem 14, can contact the teeth. The area of the teeth in contact with the stem 14 is partially cleaned due to the mechanical action of contact. This allows the stem 14 to be repeatedly withdrawn and reinserted into the interdental area, in one aspect of cleaning. Foreign matter (food debris, plaque, etc.) in the interdental area can be pushed out to the lingual side of the teeth as the stem 14 is inserted into the interdental area. Alternatively, such matter can be trapped within the grooves 32 and/or valleys 30 formed by the continuous rotation of the flange 22 of the device 10 and removed from the interdental area when the stem 14 is withdrawn.

The rod 14 can also be rotated (either manually or mechanically) after insertion. In this regard, the groove 32 and the flange 22 can be structurally arranged on the rod (particularly, wrapped around it) to assist in cleaning the interdental area. When the rod 14 is rotated counterclockwise, since the groove 32 will grip the teeth tightly, this rotation can assist the rod 14 to enter the interdental area more deeply (like a screw). This rotation can also assist in withdrawing foreign matter from the interdental area, the "drill-like manner" described above. Alternatively, when the rod 14 is rotated clockwise, this rotation can also assist in extracting foreign matter from the interdental area, that is, enclosing these foreign matter in the groove 22 and/or the valley 40 formed by the continuous rotation of the flange 22, and sending these foreign matter through the interdental area to the lingual side of the teeth. In addition, while contacting the teeth, due to friction, rotation in any direction can assist in cleaning the interdental area.

As mentioned above, the groove 32 and the flange 22 of the stem 14 can also have a second purpose, namely to assist in the delivery of tooth active material to the interdental area. In this regard, for example, the tooth active material in the cavity of the handle 12 can leave the opening 28 and enter the valley 30 formed between the successive turns of the flange 22. When the stop is turned clockwise, the tooth active material will move in the valley 40 to the interdental area and be delivered there. A large part of the delivered material will remain in the interdental area after the device is withdrawn. In this way, the interdental area can be cleaned (via friction) at the same time, and, for example, the interdental area can also be treated with medicine in this way (for example, fluoridated by the delivery of fluoride substances).
