Description

TECHNICAL FIELD [0001] The present invention relates to an ultraviolet irradiation apparatus for surface treatment of a dental implant,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet ray irradiation apparatus for surface treatment of dental implants, and more particularly, to an ultraviolet ray irradiation apparatus for use in dental implants which can be universally used in most implant products disclosed in the market, And an ultraviolet irradiation device for surface treatment.

Generally, an implant refers to a substitute for replacing a human tissue when the original human tissue is lost, but refers to implanting an artificial tooth in the dentistry. That is, a fixture made of a material that does not cause a reaction to the body to be replaced with a lost root can be inserted into the alveolar bone that has passed through the tooth, and then the artificial tooth is fixed to restore the function of the tooth.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants can prevent damage to the surrounding dental tissues and can be used stably because there is no secondary cause of tooth decay. In addition, since the implant has the same structure as the natural teeth, there is no pain or foreign body sensation of the gums, and the implant can be used semi-permanently only if it is managed properly.

Here, the implant procedure includes a first procedure in which a fixture is placed in an alveolar bone, a second procedure in which a fixture is held for a period of time (3 to 6 months) .

In detail, the primary procedure includes a gum removing step of opening the gum of a tooth missing part, a multi-step drilling step of forming a perforation to which the fixture is to be inserted, and a step of fitting the temporary teeth to the fixture placement step and the inserted fixture .

After the first-time procedure, a temporary restoration period for the bone fusion is performed. Then, the temporary teeth joined to the fixture are separated, the gums around the temporary teeth are removed, and the second procedure for inserting and fixing the final restoration is performed Thereby completing the implant procedure.

In addition, the material used for the dental implant should be made of a biocompatible material which is very stable with respect to a living tissue of a human, and it should be free of human side effects, other chemical or biochemical reactivity, or rejection of human body. In addition, it is very difficult to select a proper material because mechanical strength must be very high so that deformation or breakage does not occur even when repeated loads and momentary pressures are applied.

Therefore, development of various metals and alloys as suitable materials for the implants has been attempted, but titanium metal or titanium alloy is mainly used now. Here, the titanium or titanium alloy is not only easy to process, but also has high biocompatibility, high mechanical strength and in vivo inertness to human living tissues. However, titanium and its alloys themselves take a long time to osteointegrate when implanted into a human body, and an oxide film is formed and stability is secured as compared with other metals. However, recently, there is a need to secure more improved human stability .

In order to overcome such disadvantages, techniques for enhancing osseointegration by appropriately treating the surface of the above materials have been developed and applied. Specifically, the rate and quality of osseointegration are closely related to the surface properties and chemical composition of the implant, such as surface composition, surface roughness, hydrophilicity, and the like. In particular, implants with highly hydrophilic surfaces are known to be advantageous for interaction with biological solutions, cells and tissues.

Therefore, it has been reported that implants coated with titanium dioxide (TiO ₂ ) oxide film on titanium surface are stable in living body, excellent in biocompatibility and positive in reaction with cells, and oxidized implants are only machined It has been reported that osseointegration is significantly improved at implantation than implantation.

Conventionally, techniques such as plasma spraying, sputtering, and ion implantation have been known to coat the titanium oxide film on the surface of an implant.

In addition, a product relating to a storage container for allowing a surface treated implant fixture to maintain hydrophilicity for a long time has been introduced. However, the fixture including such a storage container has a problem of being expensive and approaching a financial burden to consumers. In addition, since the product of a specific company must be used, there is a problem that the selection is very narrow for consumers even though the price is high.

Recently, there has been disclosed a part of an ultraviolet irradiation apparatus for surface treatment capable of improving the surface modification while removing the organic contaminants attached to the surface by irradiating ultraviolet rays after mounting the implant fixture therein.

However, the above-described conventional ultraviolet irradiation apparatus for surface treatment has a problem that the fixture is heated by the ultraviolet rays to become hot. Therefore, it takes a further time to cool the fixture after the ultraviolet ray irradiation is completed, so that the implant procedure can not be performed quickly.

In addition, although some surface treatment apparatuses provided with cooling means for cooling the heated fixture are partially disclosed, when the fixture is not adequately cooled by the cooling means, There is a problem that it becomes a negative factor for stable osseointegration.

In detail, the outer surface of the fixture (f) may be formed with a screw thread to facilitate the placement of the fixture at the implant treatment site, and an engagement groove may be formed at one end thereof to fasten the abutment and the crown to the upper side. At this time, since the shape of the engaging groove varies according to the manufacturer, one end of the universal shank portion (a) is manufactured corresponding to the shape of the engaging groove.

Therefore, although the shape of the fixture (f) may be different from that of the fixture (f) according to the manufacturer, the other end (b) of the universal shank part (a) As shown in FIG.

That is, in the ultraviolet irradiation apparatus 100 for surface treatment of a dental implant according to the present invention, the universal shank portion (a) is used as a means for mounting the fixture (f) (B) of the universal shank portion (a) is formed in a shape in which the other end portion (b) is formed so as to be compatible with most fixtures Can be remarkably improved.

Further, after the surface treatment is performed in a state where the fixture (f) and the universal shank portion (a) are fastened, the fastener can be fastened to the handpiece immediately after being separated from the fastening jig portion (33) The procedure time can be significantly shortened.

Of course, a separate jig member may be fabricated to connect the fixture f to the coupling jig 33, if necessary. In this case, the coupling jig may be formed to be formed at the end of the separately manufactured jig member It is possible. The end portion (a) of the universal shank portion (a) is resiliently deformed on the inner surface of the engaging jig portion (33) so that the universal shank portion (a) is inserted and fixed more stably and the cool air of the cooling fluid is easily conducted. A pressing member such as a spring may be further provided so as to press it.

The fixture (f) is heated to a predetermined temperature or higher when exposed to ultraviolet rays irradiated from the ultraviolet ray irradiating unit (20). The ultraviolet ray irradiating apparatus (100) for surface treatment of the dental implant according to the present invention The fixture (f) heated to a predetermined temperature or more is selectively cooled to perform constant temperature control.

The cooling holder 30 in which the coupling jig 33 is formed includes an upper panel 31, a lower panel 32 and a sealing member 34. Here, the rim of the upper panel 31 has a predetermined length and a predetermined space is formed inside. The engaging jig 33 is formed at an inner edge of the upper panel 31 at a predetermined depth, and is formed to have a shape that matches the other end of the universal shank portion a. As shown in the drawing, the coupling jigs 33 may be formed to be circularly arranged along the periphery of the upper panel 31, or may be spaced apart from the upper panel 31 at predetermined intervals, And may be formed to be arranged in a checkered pattern.

The lower panel 32 is provided to cover the lower side of the upper panel 31. Here, the rim of the lower panel 32 has a predetermined length, and a predetermined space is formed inwardly, and the rim of the lower panel 32 is in contact with the extended rim of the upper panel. Thus, a substantially airtight space portion may be formed between the upper panel 31 and the lower panel 32. At this time, a sealing member 34 may be inserted between the upper panel 31 and the lower panel 32 so that the sealing force of the space is improved.

The space portion may be connected to the cooling fluid flow path through which the cooling fluid stored in the fluid tank 41 is selectively flowed so that the fixture f mounted on the coupling jig 33 is maintained at a predetermined temperature. have. The lower panel 32 may be provided with an extension pipe extending to cover the outside of the cooling fluid channel.

In detail, the cooling fluid circulating unit 40 includes a fluid tank 41 in which the cooling fluid is stored, and an outlet (not shown) formed in the fluid tank 41 so as to communicate with the outlet pipe 44 and the inlet pipe 45, 44a and an inlet 45a and an end portion of the outlet pipe 44 and the inlet pipe 45 so that the cooling fluid is circulated along the outer periphery of the coupling jig 33, ). That is, the cooling fluid discharged from the fluid tank 41 through the outlet 44a flows through the outlet pipe 44, the circulation guide portion 46, the inlet pipe 45, And is then recycled to the fluid tank 41 through the inlet 45a.

Here, the circulation guide portion 46 refers to a space portion formed between the upper panel 31 and the lower panel 32 as the rims of the upper panel 31 and the lower panel 32 are in close contact with each other, As shown in FIG.

At this time, the cooling fluid circulating unit 40 is provided with a cooling unit 43 so that the cooling fluid circulating through the cooling fluid channel is cooled. Specifically, the cooling section 43 cools the cooling fluid stored in the fluid tank 41 to a predetermined temperature by a cooling cycle. The cooling unit 43 may be a known cooling unit including a pump, a cooling fan, a radiator, and the like.

 That is, after the cooling fluid stored in the fluid tank 41 is cooled by the cooling unit 43, the cooling fluid is discharged through the outlet 44a communicated with the outlet pipe 44, (45a) communicated with the inlet pipe (45) after cooling the fixture (f) mounted on the cooling holder part (30) by flowing through the circulation guide part (46) Thereby forming a circulation structure for re-entering the fluid tank 41.

Thus, even if the fixture (f) is heated to a predetermined temperature or higher by the ultraviolet light irradiated to the surface of the fixture (f) provided on the cooling holder unit (30) The coolant flows along the cooling fluid flow path of the circulation unit 40 and transfers cool air to the coupling jig unit 33 on which the fixture f is mounted.

5, the circulation guide portion 46 is disposed adjacent to the outer periphery of the engagement jig portion 33 so as to substantially circulate the outer periphery of the engagement jig portion 33, A circulation partition wall 36 for guiding a flow path of the fluid channel may be alternately protruded.

In detail, a plurality of coupling grooves 35 through which fastening members are inserted to be fastened to the lower panel 32 are formed at an edge of the upper panel 31. A plurality of the engagement jigs 33 are formed along the periphery of the upper panel 31. Here, the engaging jig 33 may be recessed in a predetermined shape so that the end portion b of the universal shank portion a is engaged.

The circulation partitions 36 may be protruded to form a flow path through which the cooling fluid flows in the space formed between the upper panel 31 and the lower panel 32, have. Here, the circulation barrier ribs 36 protrude from the upper panel 31 and the lower panel 32, respectively, so that the predetermined space may be formed in the space portion. Here, the passage means a circulation guide part 46 which is a flow path through which the cooling fluid flows.

It is preferable that the circulation partitions 36 are alternately protruded so that the circulation guide part 46 is adjacent to the outer edge of the engagement jig part 33 so as to surround the engagement jig part 33. Therefore, when the cooling fluid circulates, the outer surface of the coupling jig 33 and the circulation guide portion 46 substantially correspond to each other, and the surface area through which the cool air is transmitted is widened, so that the fixture f can be cooled more effectively have.

Of course, the circulation guide part 46 is formed in the space defined inside the upper panel 31 and the lower panel 32 as the circulation partitions 36 are protruded, In some cases, a separate tube may be inserted between the passages formed with the circulation barrier 36 and the cooling fluid may flow inside the tube. The circulation barrier ribs 36 may protrude in a zigzag manner as shown in the figure, but may also protrude to form a coil shape, and a passage formed by the circulation barrier ribs 36 And may protrude in various forms provided that it is adjacent to the outer edge of the jig 33.

The circular partition wall 36 may protrude substantially integrally with the extended rim of the upper panel 31 and the lower panel 32. In some cases, the circular partition wall 36 may have a separate structure And such variations are within the scope of the present invention.

6 is a flowchart illustrating a cooling process of the cooling holder unit according to an embodiment of the present invention.

6, the cooling fluid circulating unit 40 may cool the cooling fluid to cool the cooling holder unit 30 when the fixture f is heated to a predetermined temperature or higher by the ultraviolet rays, .

In detail, the fixture (f) is placed on the treatment site of the subject by ultraviolet light. At this time, when the fixture (f) is placed in an excessively heated state, The procedure site tissue may be damaged, which is a negative factor for stable osseointegration. Therefore, the ultraviolet irradiating apparatus 100 for surface treatment of a dental implant according to the present invention is characterized in that the temperature of the fixture (f) is optionally cooled to constant temperature so as to maintain a predetermined temperature at which the subject does not feel discomfort Thereby providing a circulating structure of the fluid.

First, the cover portion 11 is opened to mount the fixture f to the cooling holder portion 30 provided inside. A plurality of coupling jigs 33 are formed in the cooling holder 30 and the universal shank portion a is connected to an end portion of the fixture f and the end portion of the universal shank portion a (b) is inserted into the engagement jig portion (33).

At this time, since the engaging jig portion 33 is formed to coincide with the outer surface of the other end portion (b) of the universal shank portion (a), it is compatible with most fixtures (f) released on the market. Further, since the other end portion (b) of the universal shank portion (a) is in close contact with the inner surface of the engaging jig portion (33), the engaging jig portion (33) The cool air can be quickly and smoothly conducted from the inner surface of the engagement jig portion 33 to the fixture f through the universal shank portion 33, so that the cooling power can be remarkably improved.

When the fixture f is attached to the cooling holder 30 and the cover 11 is closed and power is applied to the ultraviolet ray irradiating unit 20 as described above, (S10). Here, the ultraviolet ray emitted from the ultraviolet ray irradiating unit 20 may have a wavelength of 400 nm or less, preferably 100 to 300 nm. The organic contamination remaining on the outer surface of the fixture (f) is irradiated to the fixture (f) at a light quantity of 10 to 40 mW / cm ² , preferably 20 to 30 mW / cm ² for 5 to 15 minutes By effectively modifying the surface state while sterilizing and washing, hygienic properties are remarkably improved and surface modification such as hydrophilicity and osseointegration can be remarkably improved.

The temperature sensing means 37 provided at one side of the cooling holder unit 30 may heat the fixture f at a temperature higher than a predetermined temperature by heat when the fixture f is exposed to the ultraviolet ray for a long time. Is detected (s20). The temperature sensing means 37 may be provided at one side of the cooling holder 30 so as to be adjacent to the coupling jig 33 to facilitate detection of the temperature of the fixture f. Furthermore, the temperature sensing means 37 may detect the temperature of the fixture f itself, but in some cases it is connected to the fixture f and the heat is conducted as the fixture f is heated The temperature of the heated general purpose shank portion (a) may be detected to determine the temperature of the fixture (f).

At this time, when the temperature detected by the temperature sensing means 37 is equal to or higher than the predetermined first temperature (s30), the driving of the cooling unit 43 is started (s40) to cool the cooling fluid, Circulation of the fluid is started (s50). Here, the first temperature refers to a limit temperature at which the treatment site tissue is not damaged when the fixture (f) taken out from the ultraviolet irradiating apparatus for surface treatment 100 is placed on the treatment site of the client, It can be set at 37 ~ 38 ℃ similar to body temperature.

The control unit 60 includes an irradiation control unit 61 for driving the ultraviolet ray irradiation unit 20 and a circulation control unit 62 for controlling the cooling fluid circulation unit 40. Here, the temperature of the fixture (f) detected by the temperature sensor (37) is transmitted to the circulation controller (62). At this time, when the detected temperature is equal to or higher than the predetermined first temperature, the circulation control unit 62 applies a signal to start the operation of the cooling unit 43 provided at one side of the fluid tank 41.

The cooling fluid cooled by the cooling unit 43 is discharged to the outlet pipe 44 through the outlet 44a and then flows into the circulation guide unit 46). Since the circulation guide part 46 is circulated around the outer circumference of the coupling jig part 33 by the circulation partitions 36 protruded between the upper panel 31 and the lower panel 32, The temperature of the fixture (f) heated by ultraviolet rays can be quickly lowered.

If the temperature of the fixture (f) is lower than a preset second temperature (s60), the temperature of the fixture (f) lowered by the circulation of the cooling fluid is re- It is determined whether the cooling unit 43 is driven and whether the cooling fluid circulates (S70). Here, the predetermined second temperature may be an initial temperature detected when the fixture (f) is attached to the cooling holder (30).

That is, the temperature sensing unit 37 can sense the temperature of the fixture f from the time when the fixture f is mounted on the cooling holder unit 30, To determine whether the cooling cycle is driven or not.

Specifically, when the temperature of the fixture (f) detected again after the circulation of the cooling fluid is started is equal to or lower than the predetermined second temperature, the cooling cycle of the cooling unit (43) and the circulation of the cooling fluid are terminated (s90) . If the re-detected temperature is equal to or higher than the predetermined second temperature, the re-detected temperature is re-compared with the predetermined third temperature to determine whether the cooling cycle is driven (s80).

 Here, the third temperature may be set to a temperature between the first temperature and the second temperature, and may preferably be set to 30 to 32 ° C lower than the first temperature. That is, by setting the third temperature to be lower than the first temperature, the fixture (f) is rapidly re-heated to the first temperature by the ultraviolet rays continuously irradiated even when the cooling fluid is circulated It is possible to prevent the cooling unit 43 from being unnecessarily repeatedly driven.

More specifically, if the temperature of the re-detected fixture (f) is higher than the predetermined second temperature but higher than the third temperature, the circulation of the cooling fluid is continuously performed. However, if the re-detected temperature is higher than the second temperature but lower than the third temperature, the circulation of the driving and cooling fluid of the cooling unit 43 may be terminated (s90).

Accordingly, even if the fixture (f) is heated by the ultraviolet ray during the surface treatment of the fixture (f), the cooling fluid circulating part (40) selectively So that the fixture (f) can be cooled. Thus, the energy efficiency is improved and the energy efficiency is improved because the required cooling fluid circulation is limited so that the implants can be swiftly placed after the surface treatment in the implant treatment, and the temperature is constantly controlled within a predetermined temperature range in which the physician does not feel discomfort during the implant treatment .

For example, if the fixture (f) having an initial temperature of 17 ° C is attached to the cooling holder (30) and the detected temperature rises to 42 ° C in a state where the ultraviolet ray is irradiated for a predetermined period, the control unit The cooling cycle of the cooling unit 43 is driven and the cooling fluid is circulated. If the re-detected temperature is lower than 17 [deg.] C, which is the initial temperature of the fixture (f), the temperature of the fixture (f) gradually lowered by circulation of the cooling fluid is re- The circulation of the cycle and the cooling fluid is terminated.

If the re-detected temperature is higher than the second temperature, that is, the initial temperature of the fixture (f), the cooling cycle of the cooling unit 43 and the circulation of the cooling fluid are re- The circulation of the cooling fluid is maintained so that the cooling of the fixture (f) can be continuously performed. However, if the re-detected temperature is higher than the second temperature, that is, the initial temperature of the fixture (f) of 17 ° C, but lower than the third temperature of 30 to 32 ° C, the circulation of the driving and cooling fluid of the cooling unit is terminated .

Of course, the first temperature, the second temperature, and the third temperature may be changed according to circumstances, and the first temperature and the third temperature may be arbitrarily set by operating the control button provided on the display unit 14. [ Further, the controller may be configured to simplify and selectively circulate the cooling fluid according to the first temperature and the second temperature.

Thus, in the ultraviolet irradiation apparatus 100 for surface treatment of a dental implant according to the present invention, the circulation of the cooling fluid is selectively controlled according to the temperature of the fixture (f) detected by the temperature sensing means 37 Algorithm allows the temperature of the fixture (f) to be constantly controlled within a predetermined temperature range suited to continuous and rapid implantation procedures, thereby significantly improving the convenience of the procedure.

Since the universal shank portion (a) is used as a means for mounting the fixture (f), it can be applied to most fixtures (f) released on the market, and the usability is remarkably improved, (B) of the universal shank portion (a) so that the cool air transferred from the cooling fluid can be quickly conducted to the fixture (f) and cooled.

At this time, the temperature of the fixture (f) cooled through the circulation of the cooling fluid is automatically set to the cooling unit (43) at a predetermined temperature or lower so that the temperature of the fixture (f) And the circulation of the cooling fluid is selectively limited, so that the energy efficiency is improved and the economical efficiency can be remarkably improved.

The circulation partitions 36 are formed in such a manner that the flow path of the cooling fluid through the circulation guide part 46 is alternately protruded so as to surround the joining jig part 33 adjacent to the outer periphery of the joining jig part 33 So that the surface area of the fixture (f) mounted on the coupling jig (33) can be increased.

Here, the cooling fluid circulating unit 40 may include a cooling unit 43 for cooling the cooling holder unit 30 to selectively drive the cooling cycle such that the fixture f is maintained within a predetermined temperature range. do. At this time, as the cooling unit 43 is driven, the cooling fluid is cooled and circulated, and the cooling fluid may be provided as cooling water. Specifically, the cooling fluid may be a known liquid to gaseous refrigerant, but preferably cooling water cooled to a low temperature by the cooling portion may be used.

[

On the other hand, the ultraviolet lamp 23 is provided at an end of the light source support part 22. Here, the ultraviolet lamp 23 may be a halogen lamp, a high-pressure mercury lamp, a light emitting diode or an organic light emitting diode that emits ultraviolet rays as the light source to which the ultraviolet light is irradiated. In addition, a reflection plate that can cover the outside of the light source and reflect the ultraviolet light may be provided.

Here, the reflection plate may be individually provided so as to surround the light sources provided at the ends of the bar when the light source support unit 22 is in the bar shape. In the case of the disk plate, Or may be provided in a form to surround the rim.

Thus, as the rotation guide unit 21 rotates, the entire surface of the fixture f can be uniformly irradiated with ultraviolet rays as it is rotated at a predetermined speed to the upper side of the cooling holder unit 30.

At this time, an angle adjusting unit 24 may be provided at the end of the light source support unit 22 to selectively control the irradiation direction of ultraviolet light emitted from the ultraviolet lamp 23. Here, the angle adjusting unit 24 can be hinged or ball-rotated to elastically adjust the irradiation direction of the ultraviolet rays, so that it is easy to operate the fixture f so as to more uniformly irradiate the ultraviolet rays.

The angle adjusting unit 24 may be provided at a portion where the light source support unit 22 and the ultraviolet lamp 23 are connected to each other as described above. In some cases, the angle adjusting unit 24 may include the rotation guide unit 21, May be provided at a portion where the support portion 22 is connected or may be simultaneously provided at each connection portion.

In addition, the edge of the coupling jig 33 may further include an ultraviolet ray identification sensing unit 50 that is selectively discolored according to an irradiation amount of ultraviolet rays irradiated from the ultraviolet ray irradiating unit 20. Here, the ultraviolet ray identification sensing unit 50 may be provided with a sensor for detecting the ultraviolet ray irradiation amount and indicating a specific color or pattern, but it is possible to easily identify the ultraviolet ray irradiation amount by attaching a known ultraviolet ray detection sticker or the like.

That is, it is possible to easily check the state of the ultraviolet ray irradiated to the surface of the fixture (f) through the ultraviolet ray identification sensing unit (50) selectively discolored according to the ultraviolet ray irradiation amount, The irradiation angle can be adjusted quickly, so that the surface of the fixture (f) can be uniformly and stably sterilized and surface-modified. Furthermore, the surface treatment efficiency of the fixture (f) may be further improved by providing a reflection plate for reflecting the ultraviolet rays on the inner surface of the cooling holder unit (30) to the case (10).

Of course, the ultraviolet irradiator 100 for surface treatment may be provided with a structure in which the cooling holder 30 is rotated from a central portion as the case may be. In this case, a structure may be provided in which the rotation of the cooling holder unit 30 and the circulation of the cooling fluid channel can be made separately.
