Description

Simple Dental Impression Tray for Temporary False Tooth}

The present invention relates to a dental impression tray, and more particularly, in the treatment of temporary dentures in order to solve the inevitable condition that occurs when the denture is performed by a procedure such as a prosthesis or an implant, The present invention relates to a simple impression tray for manufacturing temporary dentures, in which a temporary denture can be manufactured.

If a natural tooth is damaged for various reasons, the dentist will apply a denture that looks like a natural tooth.

As dentures, various materials such as metal, ceramics, and synthetic resins are used. Representative methods of the procedure include prosthetic procedures for retaining dentures at the defect site using adjacent natural teeth and implants for implanting dentures in the alveolar bone.

However, the treatment of such dentures usually takes several days for prosthetics and several months for implants, so patients suffer from aesthetic damage and dietary discomfort and have no teeth at least for a certain period of time. There is a difficulty to live in a stateless state.

Therefore, in order to solve the inevitable difficulty in the period of dentures, dentists often perform temporary dentures for temporary use during the denture period. You can do it less.

Temporary dentures can be produced directly by the dentist, and in the dentist, only the model (impression) of the tooth is taken and sent to the laboratory.

The most common method of manufacturing temporary dentures directly at the dentist is the block method. Briefly describing the block method, a soft state (freely moldable) is obtained by mixing and kneading a known resin (a quick-curable resin that is harmless to human body). The process of making the resin dough of the state), the process of shaping the resin dough into blocks large enough to the size of the intended temporary dentures, and inserting the block of the solid state into the extraction site of the patient so that it bites The process of raising the occlusal surface with the bite of the tooth), the process of removing the block with the occlusal surface and hardening it, then grinding it with a grinder and fitting it to the extraction site to complete the temporary denture, and the completed temporary It is a method of adjusting the occlusion by inserting dentures into the location.

As such, the method of manufacturing and processing temporary dentures directly at the dentist is quite demanding, so it is necessary to acquire skills through repetitive training, so that only some skilled doctors or staff members, not all doctors, can perform the procedure. There is a problem.

As a technique related to a conventional temporary denture treatment that is different from the block method, there is a 'temporary false denture using veneer shell plate' of Korean Patent Application Publication No. 10-2005-0005976 (published on Jan. 15, 2005).

On the other hand, the method of requesting an external laboratory is inconvenient to visit the patient again because it can take more than one day because the temporary denture can not be provided immediately in the patient visited.

In general, in order to perform dentures at the dentist, it is necessary to obtain an intraoral dental impression of the patient. At this time, an impression acquisition tray is widely used as a mechanism for obtaining an impression of a tooth.

Impression acquisition trays have been developed in a wide variety of structures, but the basic structure is a recessed structure that can hold the impression material and a handle connected to the recessed structure.

As a technology related to the impression acquisition tray, the 'counterweight acquisition acquisition tray' of Republic of Korea Patent No. 10-0578822 (registered on May 04, 2006), Republic of Korea Patent No. 10-0597336 (2006. 06. 29. Tray for dental impressions', 'dental impression tray' of Republic of Korea Patent No. 10-0651015 (registered November 22, 2006), Republic of Korea Patent No. 10-0740647 (2007. 07. 11. 2007) And `` impression tray using impression tray '' and `` dental impression tray '' of the Korean Utility Model Registration No. 20-0378033 (registered on February 28, 2005).

However, these conventional trays are not intended for the treatment of 'temporary denture', but are developed for the purpose of treating 'dentures', and are used to produce temporary dentures having a relatively complicated structure and difficult usage. It is not suitable for use.

The purpose of the present invention is to solve the problems related to the treatment of temporary dentures as described above, the production cost is low and can be produced and performed aesthetically improved temporary dentures quickly and easily even without a skilled doctor or staff It is to provide a simple impression tray for making temporary dentures.

According to the present invention there is provided a simple impression tray for making temporary dentures.

The simple impression tray for manufacturing a temporary denture according to the present invention is a tray having an impression material accommodating part in which an impression material is accommodated and a non-sewn part formed at one end of the impression material accommodating part.

The impression material receiving portion of the tray according to the present invention, having a vertical surface located on the lip side, a horizontal surface extending laterally from the bottom of the vertical surface, and an inclined surface extending on the tongue side toward the upper side from the horizontal surface It is a shape of ordinary light.

The tray according to the present invention is formed on the inner surface of the horizontal surface is bent to maintain the impression material in place, and the upper end of the horizontal surface and the upper surface of the inclined surface is formed to catch any falling off of the impression material With chin.

The tray according to the present invention is formed of elastic synthetic resin so that the upper opening formed by the transverse surface and the inclined surface resiliently elastically opens.

Preferably, the shape of the light-lower narrowing of the impression material accommodating portion is opened at an angle of 40 degrees to 50 degrees, and the bending is a semi-cylindrical shape.

The simple impression tray for making temporary dentures according to the present invention has a very simple structure and is easy to use. There is an effect that can be performed.

Hereinafter, with reference to the accompanying drawings will be described in more detail the simple impression tray for making temporary denture according to the present invention. The following embodiments are merely illustrative of the simple impression tray for making temporary denture according to the present invention, it is not intended to limit the scope of the present invention.

As shown, the temporary impression tray 1 for temporary denture fabrication according to the present invention, the impression material receiving portion 10 and the impression material receiving portion 10, the impression material receiving portion 10 is accommodated similarly to the conventional tray. It is composed of a structure including the dexterity formed part 20, and is produced by integrally molding the impression material receiving portion 10 and the handle portion 20 by using a plastic synthetic resin having its own elasticity, to produce a 'denture' It is not intended to be used to create 'temporary dentures', but rather.

According to a feature of the present invention, the impression material receiving portion 10, when put into the oral cavity, and the transverse surface 12 extending laterally from the bottom of the longitudinal surface 11 and the vertical surface 11 located on the lip side; The inclined surface 13 which extends toward the upper side from the horizontal surface 12 is provided, and the cross section is concave shape below the upper light lower narrow.

At this time, it is preferable that the shape of the upper and lower narrow narrowings of the impression material accommodating portion 10 is approximately 40 degrees to 50 degrees, and in particular, about 45 degrees. However, in the case of the tray for manufacturing the temporary denture corresponding to the incisor teeth, it may have a narrow angle of 40 degrees or less.

The inner surface of the transverse surface 12 is formed with repeating bends 14 of semi-cylindrical shape, for example. The bend 14 serves to keep the impression material 2 in place in the impression material accommodating part 10 by widening the contact area between the impression material 2 introduced.

In addition, at the upper end of the horizontal surface 12 and the upper end of the inclined surface 13, the locking jaw 15 is formed inwardly, and the locking jaw 15 is unintentionally released from the tray 1 by the impression material 2. Prevent it.

Therefore, when the cured impression material 2 is to be drawn out, the upper opening 10a of the impression material receiving part 10 is forcibly opened and drawn out, and after the extraction of the impression material 2, the impression material receiving part 10 is a plastic synthetic resin material itself. It returns to the circle by the elasticity of.

In the illustrated embodiment, Figure 1 is a tray for taking the impression of one molar-fang, Figure 2 is a tray for pulling both the incisor-fang-molar, and A and B of Figure 4 are the incisor-fang and incisors respectively. As each of the trays to obtain the impression of the exemplified, it is natural that it can be modified in other forms to obtain the impression of the target tooth as needed.

In the tray 1 according to the present invention illustrated in FIG. 3, the length of the vertical surface 11 is about 12 mm, the horizontal surface 12 is about 4 mm, and the width of the upper opening 10a into which the impression material 2 is inserted is About 9mm, the thickness is about 1mm, the height of the locking jaw 15, about 2mm, the inner protrusion length of the locking jaw 15 is about 1mm, the protrusion height of the bend 14 is about 1mm, showing an open angle of 45 degrees.

The handle part 20 is formed at one end of the impression material receiving part 10 to be caught when the impression material receiving part 10 is put into or taken out of the oral cavity, and is not particularly limited as long as it is easily shaped by hand.

The simple impression tray 1 for temporary denture fabrication according to the present invention as described above is very simple in structure and can be manufactured inexpensively by plastic injection molding. Dentures can be made and treated.

5 and 6 will be briefly described a process of performing a temporary denture when there is a missing tooth using a tray according to the present invention.

First, an impression denture 3 of the same type and size as the extracted tooth itself or the extracted tooth is inserted into the tooth loss part 4 and temporarily held in an easily detachable manner using an adhesive (FIG. 5A and B). .

Here, the impression denture 3 is, for example, a kind of 'value' manufactured by the 'impression tooth shaping mold' filed by the inventor of the utility model with the same design as the present invention. It is the value of the tooth shape that is temporarily held in the tooth loss part (4) in order to obtain the impression corresponding to the missing tooth during the procedure in the loss part (4).

Next, the impression material 2 is put into the tray 1 according to the present invention, and the patient bites the tray 2 of the present invention into the mouth so that the impression material 2 is cured. Impressions on the teeth around them are taken (C and D in FIG. 5). At this time, if the extracted tooth or impression denture (3) attached to the impression material (2) attached temporarily to the tooth loss part (4) is removed. Thereby, the impression of the tooth loss part 4 is acquired by the extraction tooth or the impression denture 3 temporarily inserted in the tooth loss part 4.

Next, the resin 5 for temporary denture molding is applied to a part corresponding to the tooth loss part 4 of the impression material 2 in which the impression is taken, that is, the area where the impression is taken by the extraction tooth or the impression denture 3. By filling and curing, the rough temporary denture 6 to be treated at the tooth loss site 4 is formed (E in Fig. 5).

Next, the temporary denture 6 molded from the impression material 2 is taken out, and the resin debris unnecessarily attached to the periphery is simply polished with the polishing machine 7 to finally meet the tooth loss part 4 of the patient. The temporary denture 6 is completed (F and G in Fig. 6). The temporary dentures 6 thus completed are not only formed with the occlusal surfaces of the antagonist teeth, but also become temporary dentures 6 having a shape almost similar to that of the lost tooth.

Finally, the temporary temporary denture 6 is inserted and bonded to the tooth loss site 4 between the abutment 4a so that it can be used during the period of indentation until the denture is completed with a prosthesis or implant, and the resin is formed in the gap. The filling of the temporary denture 6 is finally completed by filling with (H and I in Fig. 6).

As described above, when the temporary denture is used using the tray 1 of the present invention, only about 10 minutes of treatment time can be performed without the skilled technique, and the temporary denture can be performed accurately and with good esthetics.

As described above, according to the present invention, the prosthesis for fixing the denture to the sharply cut abutment of the Republic of Korea Patent Publication No. 10-2005-0005976 (figure 2 in Fig. 2) or to fix the denture by implanting the artificial tooth root In the case of implantation, the tray 1 of the present invention is used to obtain the impression of the abutment and the artificial root, and then the temporary dentures are formed from the temporary denture forming resin, as in the aforementioned method. Temporary dentures can be performed.
