Description

The present invention relates to a dental accidental ingestion preventive tool that prevents a patient from accidentally swallowing a prosthesis during dental treatment.

2. Description of the Related Art Conventionally, a dental treatment performed in a dental clinic or the like is generally performed by sitting a patient in a dental treatment chair, tilting the backrest backward to lie on the back, and opening the mouth.

In addition, an operator such as a dentist who performs dental treatment may attach a prosthesis to a treatment site or a site where teeth are lost to a patient in such a supine state to supplement the site.

This prosthesis is, for example, a relatively large one such as a partial denture, but is also a relatively small one such as a crown or a dental tool used for implant treatment, and thus the operator is required to perform delicate work.

In particular, most of the dental tools used for the above-mentioned implants are fixtures that are attached to the jawbone, abutments that are attached to the fixtures, and mounting screws that are attached to this abutment. The dental appliance must be adjusted and mounted in the patient's mouth multiple times.

When performing this attachment work, the surgeon is careful to prevent the prosthesis from falling into the oral cavity of the patient. However, since the tweezers or the like that holds the prosthesis may slip with saliva, and the patient is on the back, there is a concern that the prosthesis may fall in the pharynx direction. Particularly when the prosthesis reaches the vicinity of the uvula, the patient tends to reflexively swallow.

Therefore, a mouse having an elliptical frame formed of an elastic body is stretched with a net having finer eyes than the prosthesis, and the entire frame is curved into a substantially U shape in a side view and inserted into the oral cavity to be mounted. A net has been proposed (for example, see Patent Document 1).

According to such a mouse net, even if the prosthesis falls into the oral cavity, the prosthesis can be captured by the net before the patient swallows.

In the following, first, a specific configuration of the dental accidental ingestion preventive tool will be described, and then a method of using the dental accidental ingestion preventive tool will be described.

[Overall structure of dental accidental ingestion prevention device]
The appearance of the dental accidental ingestion preventive tool according to the present embodiment is shown in FIGS. 1 is an overall perspective view of a dental accidental ingestion preventive tool, FIG. 2 is a plan view thereof, FIG. 3 is a front view thereof, FIG. 4 is a rear view thereof, and FIG. 5 is a right side view thereof. The bottom surface of the dental accidental swallowing prevention tool appears in the same manner as the plan view shown in FIG. 2, and the left side surface appears symmetrically with the right side view shown in FIG.

The dental accidental ingestion preventive tool of the present embodiment is formed in a substantially Ω shape in a plan view, sandwiches a sheet of gauze or the like, and attaches it in the oral cavity of the patient, so that the operator accidentally drops the therapeutic tool or the like. However, the therapeutic device is captured by a sheet to prevent accidental ingestion, and its structure is as follows.

The dental accidental swallowing prevention tool 1 of this embodiment attaches/detach a substantially U-shaped intraoral retainer 2 that is urged in an expanded state by elastic force as shown in FIGS. 1 to 5 and a seat 30. The left and right holding parts 3 and 3 which can be freely mounted and the inside of the concave part 5 while bending inwardly at the free end of the intraoral retainer 2 and the left and right edges A and A of the lip (Fig. 6 and FIG. 7), and lip contact portions 4 and 4 formed so as to engage with the lip engagement portions 4 and 4, and contact flat portions 6 and 6 formed at the tips of the lip engagement portions 4 and 4.

The intraoral holder 2 is cut at the top of the intraoral holder 2 and is constituted by a left half frame portion 10 having a semicircular arc shape and a right frame portion 10 having a semicircular arc shape, and each frame portion thereof. A coil spring portion 11 is continuously provided at the base ends of the terminals 10 and 10, and end piece portions 12 and 12 made of dental resin are formed at the continuously provided portions. That is, the left and right frames 10, 10 of the intraoral holder 2 are urged in the outward direction, that is, in the expanding direction of the intraoral holder 2 by the spring urging of the coil spring portion 11. Although the coil spring portion 11 is a coil spring, it may be a plate spring having a biasing force.

Left and right clamping spring bodies 7, 7 formed by bending a rod-shaped metal into a symmetrical loop shape are connected to the left and right central portions of the left and right frame portions 10, 10 of the intraoral holder 2 in a row. The spring bodies 7, 7 are provided so as to project along the U-shaped intraoral holder 2. Further, the left and right central portions of the left and right frame portions 10, 10 in which the holding spring bodies 7, 7 are provided in series form abutted enlarged portions 8, 8 made of dental resin and having a rhombus shape in a side view.

That is, the U-shaped intraoral holder 2 and the left and right holding spring bodies 7, 7 constitute left and right holding portions 3 and 3 to which a seat 30 for receiving a dental tool can be detachably mounted. A sheet holding space S for attaching the sheet 30 is formed in the portions 3 and 3.

When the seat 30 is attached to and removed from the left and right sandwiching portions 3 and 3, the seat 30 is passed through the seat sandwiching space S so that the left and right sandwiching portions 3 and 3 can sandwich the sheet 30, that is, the molar teeth in the oral cavity D. It can be widely covered with the sheet 30 sandwiched from C to the pharynx E (see FIGS. 6 and 7). Moreover, the abutting expanded portions 8 and 8 are held in contact with the inner wall F of the oral cavity so as to spread outward and form a space between the tooth and the inner wall F of the oral cavity, which will be described later. This has the effect of facilitating the work of unfolding the seat 30 or the work of attaching the implant, and further has the effect that the posture of the dental accidental ingestion preventive tool 1 can be stably maintained.

In the middle part of the left and right holding spring bodies 7, 7, pressing portions 13, 13 having a downward convex shape are formed. When the seat 30 is attached to the left and right holding portions 3 and 3, the pressing portions 13 and 13 press the seat 30 against the tongue G, so that the seat 30 can be prevented from floating.

The left and right lip engaging portions 4 and 4 are formed at the free ends of the left and right frames 10 and 10 of the intraoral holder 2, and the left and right lip engaging portions 4 and 4 are flat plates of the left and right frames 10 and 10. -Shaped metal free ends are bent inwardly to form concave portions 5 and 5, and the inside of each concave portion 5 and 5 is engaged with the left and right edges A and A of the lip. Is configured as follows.

Specifically, the concave portions 5 and 5 are bent in a plan view L-shape or in a plan view reverse L-shape and a first bent portion 5a and a plan view L-shape or a plan view reverse L-shape. The second bent portion 5b is composed of the second bent portion 5b, and one of the first bent portions 5a abuts from the oral cavity inner walls F, F to the left and right edges A, A in the oral cavity D, and the other second bent portion 5b has the left and right edges A, A. From A to the outer skin surface B comes into contact. A contact flat portion 6 to be described later is formed at the tip of the concave portion 5.

When the dental accidental swallowing tool 1 is inserted into the oral cavity, the concave portions 5, 5 of the lip engaging portions 4, 4 engage with the left and right edges A, A of the lips, so that the mouth is moved in the left-right direction. There is an effect that the opening posture is maintained so that the opening posture can be maintained by pushing it open.

The contact flat portion 6 is formed in a substantially cross shape by surrounding the tip end portions of the concave portions 5 and 5 with dental resin, and the outer surface 6a of the contact flat portion 6 has a substantially heart shape. The knob portions 9, 9 are formed so as to project.

That is, when the left and right knobs 9 and 9 are gripped and the intraoral holder 2 is inserted, the contact flat portions 6 and 6 directly contact the outer skin surface B of the lips, that is, the lip of the mouth, It is possible to prevent a part of the metallic material at the tip of the concave portion 5 from coming into contact with the skin surface as much as possible, which has the effect of eliminating discomfort to the patient. When the left and right grips 9 and 9 that are grasped are brought close to each other, in order to resist the biasing force of the coil spring portion 11, the expanded intraoral holder 2 is contracted, and the surgeon is in the oral cavity D of the patient. There is an effect that it can be easily attached to or detached from.

The abutting flat portion 6, the abutting enlarged portion 8, the picking portion 9, and the end piece portion 12 are made of a dental resin, so that they can be easily configured to be thick and wide.

A detailed description will be given below of a method of using the dental accidental ingestion preventive tool 1 configured as described above by the operator in the oral cavity D.

[How to Use Dental Ingestion Prevention Tools]
Hereinafter, a method of using the dental accidental ingestion preventive tool will be described with reference to FIGS. 6 and 7.
First, when the sheet 30 is attached to the holding portions 3 and 3 of the dental accidental ingestion prevention tool 1, the sheet 30 such as gauze is passed through the sheet holding space S, and the left and right holding portions 3 and 3 hold the sheet 30. It will be in the state of doing. On the other hand, the patient is in a supine position so that the head thereof faces the ceiling.

The operator inserts the intraoral holder 2 into the oral cavity D of the patient while holding the left and right picked portions 9 of the dental accidental ingestion prevention tool 1. That is, when the knob portions 9 are brought close to each other, the spring biasing force of the coil spring portion 11 is resisted, and the intraoral holder 2 can be easily inserted into the oral cavity D in this contracted state.

Then, when the left and right knobs 9, 9 are released, the intraoral holder 2 is expanded by the urging force of the sandwiching spring body 11, that is, the abutting enlarged parts 8, 8 push out both side walls F, F of the oral cavity. It will be in a state of being. At this time, the left and right lip engaging portions 4, 4 engage with the left and right edges A, A of the lips and open so as to push the mouth open in the left and right directions to maintain the opening posture. .. That is, the operator can smoothly perform the work of spreading the sheet 30 described later from the mouth of the opening posture that is largely pushed open, or the work of attaching the implant and the like.

Next, the operator pushes and spreads the sheet 30 sandwiched between the left and right holding parts 3 and 3 to cover the posterior teeth C in the oral cavity D from the molar C to the pharynx E. At this time, the pressing portions 13, 13 of the left and right holding portions 3, 3 press the lower end of the seat 30 against the tongue G, that is, the seat 30 does not rise even if the patient moves the tongue G. The lower end of the seat 30 can always be closed.

As described above, by mounting the dental accidental ingestion preventive tool 1 in the oral cavity D of the patient, since the sheet 30 is occluded from the molar C to the pharynx E in the oral cavity D, the implant mounting work thereafter is performed. In this case, even if a dental tool such as a screw is dropped in the pharyngeal direction, the patient is prevented from swallowing because it is caught by the closed sheet 30.

When the attachment work of the implant is completed, when the left and right knobs 9 and 9 are grasped and the knobs 9 and 9 are brought close to each other, a state in which the urging force of the holding spring body 11 is resisted, that is, the lip The engagement state between the left and right edges A and the lip engagement portion 4 is released, and the intraoral holder 2 can be pulled out of the oral cavity D at once in this state.

By following the above-described method of use, the operator can easily attach or remove the dental accidental ingestion preventive tool 1 in the oral cavity D of the patient.
