Wax denture production method for dental dentures {pre wax denture product method for dental product}

The present invention relates to a wax denture for making a denture. After fixing the base plate to the teeth of the denture, placing the wax denture on top of the denture, adjusting the occlusal surface, and then opening the gap with wax. Fill the area and melt the wax to connect the wax dentures, which consist of the upper and lower jaw, and the upper and lower jaw consists of anterior teeth and posterior teeth, respectively. By making the check, the working time of making an actual denture is shortened, and even a general person can easily manufacture it. It is related to a method of manufacturing a wax denture for making a denture where doctors can directly view an oral arrangement of teeth connected to a gum by a denture made of wax. .

In general, a denture that can be removed and replaced by an implanted patient can be used instead of an implant, and the general procedure for making such a denture is one-step, and the doctor opens an impression.

A laboratory or dental technician, with this clinical practice, pours plaster to create a model that reproduces the shape of the gums and teeth.

Based on this, as a second step, the laboratory creates a horseshoe-shaped structure called Wax Rim with a height of 18 mm for the mandible and 22 mm for the maxilla, for example.

This structure serves to secure the height of the maxilla and the mandible and the location and location of the teeth.

At this time, at this time, the height of the Bite is rarely increased, and it is adjusted by lowering it, and the upper and lower jaw bite (articulation) information called Bite is given to the laboratory.

As a third step, the laboratory goes to this information from the doctor and sets up the teeth again. With Wax rim and Bite, you can make dentures.

As a fourth step, the laboratory sends a beauty and wear test to the doctor in wax after the teeth are finished. The doctor will check and supplement the denture in the patient's mouth.

As a fifth step, the laboratory receives a wax denture from the doctor, and through the process called processing, it replaces the wax with dental resin (gum, pink), trims and polishes it to complete the denture.

For reference, the teeth made of white PMMA are used in all processes, and they do not change until the work is completed in? Up. Finally, when all the work is done, only the bite is adjusted slightly.

And as a conventional patent technique for a common denture manufacturing method, Patent Registration No. 10-1762516 includes a step A of forming a denture-integrated gum in which dentures are integrally planted on a gum formed of wax;

A step B of forming the denture-shaped gum formed in step A into a denture model (1);

After inserting the bonding layer 10 of the tooth 8 into the dentin mold frame 20, 20a, a resin having a hardness higher than that of the bonding layer 10 of the tooth is injected into the upper surface to inject resin. Forming the dentin layer 12 of the tooth,

After inserting the dentin layer 12 integrally combined with the bonding layer 10 of the tooth 8 into the enamel mold frame 22 and 22a, the upper surface has a transparent color than the dentin layer 12 of the tooth. A denture manufacturing method using a tooth mold is disclosed, characterized in that it comprises the step of molding a resin enamel layer 14 by injecting a resin of high hardness.

However, since the conventional denture manufacturing methods are made by directly manufacturing and wearing the denture, it is difficult to precisely adjust the distance between the maxilla and the mandible, and thus there is a disadvantage that a defect occurs during production or excessive time is consumed during production.

Therefore, the present invention has been devised to solve the above problems. Before making a denture product to be actually used, it is possible to make a denture made of a wax material in advance, thereby shortening the working time of making an actual denture and making it easy for the general public. The purpose of the present invention is to provide a method for manufacturing a wax denture for manufacturing a denture in which the tooth arrangement connected to the gum by a denture made of wax is directly visible in the oral cavity.

The present invention relates to a method for manufacturing a wax denture, after fixing the wax base plate to the gum of the wax denture, adjusting the occlusal surface, filling the gap with wax, melting the wax to connect, and connecting the wax denture to the maxilla It consists of the mandible, and the mandible is characterized by consisting of anterior and posterior teeth, respectively.

The present invention shortens the working time of making the actual denture by making the denture made of wax material before making the denture product to be actually used, and even the general public makes it easy, and doctors arrange teeth that are connected to the gums by the denture made of wax material. There is a remarkable effect that can be seen directly in the oral cavity.

The present invention relates to a method of manufacturing a wax denture for making a denture. After fixing the wax base plate to the gum of the wax denture, adjust the occlusal surface, and then fill the gap with wax.

Melt the wax and connect.

The wax denture is composed of the upper and lower jaw, the upper and lower jaw is characterized by consisting of anterior and posterior teeth, respectively.

In addition, the measurement length between the left and right anterior teeth of the maxilla is the sum of the length between the left and right anterior teeth and the horizontal length of each of the left and right anterior teeth, and the measurement length between the left and right anterior teeth is half of the length between the left and right anterior teeth and the left and right anterior teeth. It is characterized by being combined.

In addition, if the occlusal surface is high, the bottom surface is rubbed with a hot plate to lower the height of the bottom surface, thereby lowering the occlusal surface of the upper and lower jaw. If the occlusal surface is low, it is filled up and down by filling the lower part with wax as necessary. It is characterized by raising the occlusal surface of evil.

The present invention will be described in detail with reference to the accompanying drawings.

When making dentures of the maxilla in the present invention, one set of anterior and posterior teeth is used. That is, UA and UM. The dentures below are also LA and LM. All of them are numbered for convenience. Therefore, to make a denture of a person with a small oral cavity, a small size mold is used, for example, the upper U2M2, the lower L2, and M2.

If the arch of the oral cavity is small, a small size mold is selected, and if it is large, a large size mold is selected.

The measurement length between the left and right anterior teeth of the maxilla is the sum of the lengths between the left and right anterior teeth and the respective horizontal lengths of the left and right anterior teeth (that is, if the size of the left and right anterior teeth is the same, it corresponds to the length between the left and right anterior teeth and one transverse length). The measurement length between the left and right posterior teeth is also the sum of the length between the left and right posterior teeth and the horizontal length of each of the left and right posterior teeth.

The distance between the teeth of the denture with respect to FIG. 1 is described as follows.

upper + posterior

UF2 is TS2 + N3 (30) is 43mm

UF3 is TS3 + N3 / N4 (32) is 44.5mm

UF4 is TS4 + N5 (34) is 46mm

UF5 is TS5 + N5.5 (35) is 47.5mm

UF6 is TS6 + N6 (36) is 49mm

lower + posterior is

LF2 is L2 + N3 (30) is 40mm

LF3 is L3 + N3 / N4 (32) is 41.5mm

LF4 is L4 + N5 (34) is 43mm

LF5 is L5 + N5.5 (35) is 44.5mm

LF6 is L5 + N6 (36) is 46mm.

In the formula, N is a notation for a molar mold used in front of a number indicating the size of the molar.

Posterior is the molars, Upper is the maxilla, Lower is the mandible, and for reference, the Anterior is the front teeth.

Occlusion is an occlusal, that is, chewing food.

For example, if the section from the upper and lower jaw to the front teeth is divided into several sections in front and rear, and measuring the upper + posterior and lower + posterior for each section, connecting the faces that touch each tooth creates an arc.

In the above formula, the size of the mold can be known by measuring the size of the gum, so the selection of the size of the oral cavity and the size of the mold becomes more accurate.

The denture made of wax is immersed in water in a container at a temperature of about 40 to 60 ° C, and when the lower part of the container is heated with a gas torch, the wax is soft and can be finely adjusted in the form of occlusion and arch.

The wax denture of the present invention can be cut with some knives and used as a wax denture for partial denture production.

In order to control the height of occlusal surface, or occlusion, if the bottom surface is melted with a hot plate, the height of occlusal surface is reduced.

Wax can be added to the bottom surface to fill the occlusal surface.

For reference, the general height of the upper jaw is 22 mm and the lower jaw is 18 mm, but it is common practice to gradually decrease depending on the degree of wear of the teeth and the condition of the jaw joint. In rare cases, it may be necessary to increase it. So, in order to add or lower the height, the wax needs to be melted and removed or added. Therefore, it helps when the shape is flat. Soon, the shape of the gum is flat, without following the shape of a hill with a long cylindrical shape or the shape of the gum.

This is because it is easy to follow the hill shape, but it is difficult to correct the occlusal surface of the teeth.

That is, if the occlusal surface of the present invention is high, the occlusal surface of the upper and lower jaw can be lowered by rubbing the bottom surface with a hot plate to lower the height of the floor surface.

Conversely, if the occlusal surface is low, the occlusal surface of the upper and lower jaw can be increased by filling the lower part with a wax as necessary.

After fixing the base plate to the denture gum,

Adjust the occlusion as above, then fill the gap with wax

Melt with wax to connect.

If the denture manufacturing method of the present invention is described in a process order as an example of the present invention, as a first step, a doctor opens an impression as in the prior art.

A laboratory or dental technician, with this clinical practice, pours plaster to create a model that reproduces the shape of the gums and teeth.

On the basis of this, in step 2, the laboratory creates a horseshoe-shaped structure called Wax Rim with a height of 18 mm for the mandible and 22 mm for the maxilla, for example.

This structure serves to secure the height of the maxilla and the mandible and the location and location of the teeth.

At this time, dentists rarely increase or decrease the height of the bite, which is a general-purpose tool for checking occlusion by closing the patient with the upper and lower jaw shapes commonly used in dentistry. Gives the mandibular bite (articulation) information to the laboratory.

And the next step is to use the new process of the present invention, by using a wax denture (pre wax denture) for making the denture of the present invention to lower the bite by melting the wax on the bottom surface of the wax denture with a hot plate, or sometimes to the bottom surface Fill with wax. To facilitate this, the bottom surface is a flat structure.

When using the pre wax denture of the present invention, there is no need to spend a lot of time in a delicate process when making dentures or dentures in a laboratory.

There are molds for each size, so you can quickly select a tooth that fits the size of your mouth.

On the other hand, in the conventional method, when individually setting up individually, there is no size information of the whole, and it is inconvenient to repeatedly select and fit different sized teeth repeatedly because it is found that the tooth size is wrong during setup.

The production of dentures may not be of good quality depending on the skill level of the functional and cosmetic parts depending on the person, but the present invention can facilitate the general public, improve the quality, and supply dentures to patients in the shortest period of time. have.

It can usually be completed in less than one week instead of three or four weeks, and in a hurry it will be possible in one day.

In other words, as described in the background art of the present invention, in the denture production method comprising the first 1 to 5 steps, the present invention is omitted in steps 3 and 4, and a new new composition and effect of the present invention is applied. The last step of the method corresponds to the 5th step in the conventional denture manufacturing method, and the laboratory replaces wax with Dental Resin (gum area, pink color) through a process called processing, and polishes and polishes it to complete the denture.

Soon, a wax bite is placed on a wax base plate, and 16 teeth of acrylic material are formed thereon, and the set of 16 teeth is not individual, but is manufactured by a mold integrally in the workshop. There are features. The set of 16 teeth integrally made by injecting the molten acrylic material into the mold and cooling it, then pulling it out, is distinguished by coloring between each tooth. Since it is corrected afterwards, it is accurate to select the one that fits the size in several tooth set models consisting of 16 teeth compared to the conventional method in which one tooth was attached one by one. When attaching one by one as in the prior art, there is a disadvantage in that it is not possible to immediately recognize the size or the like when working, and it has to be redone. Moreover, since the teeth between the teeth are pre-divided by a set of 16 teeth in advance, it is not necessary to work by dividing the teeth by coloring before planting the teeth as before.

Therefore, the present invention shortens the working time of making an actual denture by making a denture made of wax material in advance before making a denture product to be actually used, and even the general public makes it easy, and doctors make teeth that are bonded to the gums by a denture made of wax material. There is a remarkable effect that the arrangement can be seen directly in the oral cavity.
