Description

Frame for occlusal surface of a tooth}

The present invention relates to the improvement of the tooth restoring method, and more particularly, to a tooth occlusal surface shape and a method for manufacturing the occlusal surface to facilitate the formation of the occlusal surface in the tooth restoring portion.

There are many ways to repair a tooth at the dentist. Among them, the method of restoring the tooth color using the composite resin is an excellent treatment method compared to the amalgam restoring method, which has been widely used because of maintaining the tooth color, improved physical properties, and adhesion to the tooth. It is recognized.

The restoration method of the composite resin is as follows.

First, the caries is removed from the teeth to form a cavity, and the composite resin is well filled so that no bubbles are formed therein. The surface of the composite resin thus filled is cured by light irradiation. Finally, a curved surface is formed on the cured composite resin so that natural teeth can be occluded.

On the other hand, the occlusal surface of these teeth is very complicated in shape. In general, the dentist does it directly while observing the occlusion. However, since the occlusal surface formation process is performed directly by the operator in the oral cavity of the patient, there is a problem in that the degree of naturalness is greatly increased according to the ability of the operator, and the procedure time becomes very long.

1 is a cross-sectional view showing a manufacturing example of the tooth occlusal surface according to the present invention.

Accordingly, an object of the present invention is to provide a method for shortening the treatment time due to occlusal surface formation and allowing a natural occlusal surface formation of a certain degree or more regardless of the ability of the operator in the dental restoration method using a composite resin. .

In order to achieve the above object, the present invention provides a tooth occlusal surface, characterized in that having a concave-convex surface, such as a human occlusal surface.

The occlusal surface mold may be made of a transparent or translucent material.

The occlusal surface may be made of any one of soft PVC or urethane.

The tooth occlusal surface has a handle and a light receiving portion for light irradiation.

The light receiving portion of the tooth occlusal surface may be made of an inclined surface.

The present invention also provides the above-described dental occlusal surface mold and its manufacturing method.

This manufacturing method comprises the steps of acquiring an impression from a human tooth or a tooth model with a rubber impression agent, manufacturing an upper and lower work model in which a material injection space of an occlusal surface is formed from the raised surface; Injecting and solidifying characterized in that it comprises the step of completing the product.

The soft material may be transparent or translucent.

Hereinafter, with reference to the accompanying drawings will be described in detail the tooth occlusal surface according to the present invention and its manufacturing method.

1 is a cross-sectional view of the upper, lower working model for producing a dental occlusal surface mold according to the present invention.

In the drawings, reference numeral 1 denotes an upper working part, 2 pressing parts, 3 a light receiving part, 4 a wax filling part, 5 a material injection tube, 6 a fixing part, 7 a tooth model, and 8 a lower part working model.

First, an example of the manufacturing method of the automatic occlusal surface forming machine according to the present invention will be described. However, the following description is merely exemplary, and various applications may be made in the specific method configuration as long as the product of the present invention does not depart from the scope of the claims.

The embodiment according to FIG. 1 shows an example in which an occlusal surface is obtained from a healthy mandible right first molar of a person. First, an impression is acquired by a precise rubber impression agent of a mandible right first molar. Optionally, it is also possible to form a real sample using an artificially made tooth model or the like.

Subsequently, a working model is manufactured using precise dental high-strength gypsum on the raised surface. In addition, all parts of the work model except occlusal surfaces are made of plaster to form an isolation wall. The above model is called a downward working model (8).

Subsequently, the separating agent is applied, and a pressurizing portion 2 capable of applying pressure by hand pressing directly above the occlusal surface using a dental wax is made. In addition, by using a dental wax to create a light receiving portion (3) that can accommodate the end of the light irradiator at an angle of about 45 degrees to the left and right sides of the structure to apply pressure by hand, and finally hand in front of the pressing unit (2) Make a handle (not shown) for easy grip.

After the production using the wax, the injection pipe (5) for injecting the soft material is mounted, and the separating agent is applied to the lower working model and the wax.

Subsequently, the upper working model is manufactured again using dental high-strength gypsum.

The completed work model is composed of upper and lower parts, and the material injection tube protrudes out of the upper structure. In addition, it is preferable to form the fixing part 6 on the contact surface of the upper part and the lower part so that the upper and lower work models may not shift | deviate from each other. After the work is finished, wash off the wax with warm water and apply the separator to the inside.

When the separating agent is applied and dried, the upper and lower working models are combined, and the material on the elastic, tough, and light-transmitting gel is injected through the material injection tube 5 under pressure. At the end of the injection, wait for the material to become solid and then separate and destroy the gypsum to complete the product.

Although dental gypsum was used to produce dental occlusal surfaces in this embodiment, it is also possible to optionally use other materials, for example metallic materials.

In this case, various materials may be used as the gel-like material and are continuously developed. A preferred example of the materials developed to date is soft PVC. Soft PVC can be purchased in the form of liquid and powder, and the two components are mixed and pushed into the injection tube (5) and then placed in cold water to become a solid state.

It is also possible to optionally use a transparent or translucent soft material such as urethane or the like as the gel material.

By the above method, the occlusal surface auto-former according to the present invention having a handle having an occlusal surface on the lower surface is manufactured.

Dental occlusal surface mold according to the present invention can be prepared in advance by acquiring from a plurality of sample tooth surfaces, the more the type of the variety becomes wider selection when applied to the actual teeth.

Hereinafter, a method of using the tooth occlusal surface manufactured in this way will be described.

First, the operator removes the caries of the patient's teeth, and then fills the resin with the appropriate color and strength to the cavity from which the caries is removed so that bubbles do not occur. Then, the tooth occlusal surface according to the present invention is selected to have a similar size to the patient's treatment target tooth, and put on the occlusal surface of the tooth.

At this time, since the resin is in a gel state, excess resin flows out into the gaps and is filled along the bend of the sound mold according to the present invention. In this state, light irradiation is performed without removing the pressure.

At this time, the sound shape according to the present invention is formed with a light receiving portion inclined downward, so that light irradiation is not impeded to the resin. When such light irradiation is made, the resin in the gel state is adhered to the tooth in a solid state, and when the sound shape is removed, the tooth has an occlusal surface where a small anatomical structure is reproduced.

As described above, the tooth occlusal surface mold according to the present invention has an effect of making the occlusal surface more natural while shortening the procedure time by easily forming the occlusal surface during the dental procedure for filling the composite resin.
