Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a denture-

The present invention relates to a denture, and more particularly, to a denture which is made of a soft material integrally formed at a joint portion of a denture which is in contact with a gum, so that a denture wearer can be prevented from feeling pain upon ingesting food, And a method of manufacturing the same.

Generally, human teeth are composed of 32 teeth including upper teeth and lower teeth, and some teeth that have been lost or damaged during life are replaced with artificial teeth such as implants.

However, with age, gingival diseases such as periodontitis, depression of the pubic bone, and aging of the nerves cause natural teeth to be lost.

Therefore, those who have lost their teeth will wear the dentures that have the same shape as the lost teeth in order to replace the lost teeth.

A conventional denture manufacturing process will be described below.

The impression material is used to open the bone of the patient's teeth in the dentist, and the toothbrush manufactured in the dentistry is sent to the laboratories.

Using the personal tray prepared as described above, the patient's tooth pattern is reopened in the dentistry, and then the tooth pattern is sent back to the laboratories. In the laboratories, the base or frame is made of medical plastics and sent to the dentist. Place the image or frame in the patient's mouth and adjust the height to send it to the laboratory.

In the laboratories, dentures are prepared by arranging teeth on the base or frame, the height of which is controlled by the dentist.

The denture with the teeth prepared as described above is sent back to the dentist and the dentist adjusts it to the patient's teeth.

If the patient satisfies the denture, the wax denture is replaced with a hard acrylic resin.

However, if the food is prepared with the denture fabricated as described above, the soft food can be easily chewed. However, the hard food has a disadvantage that the gum is irritated and difficult to chew.

More specifically, since the denture is made of a rigid material that bonds to the gum, it is necessary to squeeze the gum into the denture when hard food is put into the mouth and the denture is pressed against the denture. .

In addition, when food is consumed while wearing the denture, there is a disadvantage that the user feels a lot of pain when the food dregs are caught between the denture and the gum.

In addition, the dentures are used while being worn on the gums and when they are consumed with food, this phenomenon is an essential phenomenon. When the denture moves in the gums, there is a disadvantage that foreign substances are put in the gaps. There is a problem that the gums are irritated and cause severe inflammation.

In recent years, in order to solve the above problems, a denture made of a soft material has appeared in a portion of the denture which is engaged with the gum.

Dentures with a cushion plate of the Korean Utility Model Registration No. 20-0298315, dentures with a comfortable gum in the Korean Utility Model No. 20-2010-0001864, and dentures in Korean Patent No. 10-1409084 were found.

However, the above-mentioned denture with the cushion plate of the former is formed by inserting the cushion plate into the gingival joint part of the denture, and when the denture is worn, the denture is easily removed.

In addition, the above-described gum-compatible denture is made by nontoxic gels in the gingival joint part, which has a short life span of the denture due to the non-toxic gel, and it is difficult to attach the non-toxic gel to the denture.

On the other hand, the denture is formed by attaching a silicon pad body having elasticity to a smooth surface after smoothing the gingival surface of the denture.

However, the above-mentioned denture has a disadvantage in that the silicone pad body is separated from the denture when used for a long time, and since the denture and the pad body must be manufactured respectively and then the pad body must be attached to the gingival surface of the denture, the operation is complicated and difficult, There is a problem that the manufacturing cost of the battery is high.

Korea Utility Model Registration System 20-0298315 (Date of Publication: December 16, 2002) Korean Utility Model Publication No. 20-2010-0001864 (published on February 22, 2010) Korean Patent No. 10-1409084 (Publication date June 11, 2014)

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a dental implant which can prevent the denture from being lost by integrally molding elastic silicon on the gum interface surface of the denture and prevent the wearer from feeling pain when consuming food It has its purpose.

It is a further object of the present invention to provide a denture that can be manufactured easily and easily, thereby shortening the manufacturing time, thereby reducing manufacturing cost.

Means for solving the above problems will be described as follows.

A tray manufacturing process in which a bone of a patient is opened in a dental clinic using an impression material, a tooth pattern prepared in a dental clinic is sent to a laboratory, and a tray is manufactured using a tooth pattern in a laboratory;

An embodiment of the present invention is characterized in that the polishing depth is set to 0.2 to 2 mm in the polishing step.

In an embodiment of the present invention,

The same effects as those of the present invention can be obtained by inserting a denture into a mold manufactured by the mold manufacturing process and injecting a liquid epoxy into a portion (cavity) polished through a gate.

According to the present invention as described above, the soft silicone is integrally formed with the portion of the denture that contacts the gum, so that when the denture compresses the gum, the user has the effect of buffering the pain, It is possible to prevent the silicone from being separated because the joining portion is formed integrally with silicon.

In addition, since the present invention is a method of integrally molding soft silicone into the denture, the manufacturing time can be shortened by simplifying the process compared with a conventional method in which a denture and a silicone pad are separately manufactured and then bonded with an adhesive.

Therefore, the present invention is a useful invention which can prevent the denture from being easily lost because the soft silicon is integrally formed in the gingival joint portion of the denture.

1 is a block diagram showing a manufacturing process of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

As shown in FIG. 1, a dentist removes lost teeth or damaged teeth using impression materials to restore lost teeth or damaged teeth in a patient's teeth.

As described above, when a dental bone block prepared in a dental clinic is sent to a laboratory, a tray is manufactured using a tooth block in a laboratory.

When the personal tray prepared as described above is sent to the dentist, the patient's tooth pattern is re-opened using a tray in the dentistry, and then the teeth bone is sent back to the laboratories. In the laboratories, Base frame or frame is made.

As described above, the frame manufactured by the laboratory is sent back to the dentist. In the dentist, the frame is inserted into the patient's mouth, and the height is adjusted to correct the frame.

As described above, when the modified frame is sent to the laboratory, the laboratory places the teeth on the frame.

When the denture is placed back into the dentist as described above, the dentist undergoes a corrective process in accordance with the patient's teeth.

When the denture modified by the correction process meets the gum of the patient and the patient permits, the denture is sent to the laboratories to replace the modified denture with a hard acrylic resin.

According to the present invention, since the finished denture made of acrylic resin is made of a hard material, when the denture is worn, the gums are squeezed to cause pain.

Therefore, a portion of the denture finished with acrylic resin is polished and cut by 0.5 to 1 mm using a grinder, and the upper and lower dies are again manufactured using the denture.

In this case, the upper and lower molds are fabricated by using silicon as a mold, and liquid silicon is injected into the polished portion formed at the gingival portion of the denture to inject the liquid silicone so that the denture is restored to its original state. Thereby forming a cavity.

When the mold is completed, the dent made of acrylic resin is inserted into the mold, and the upper and lower dies are coupled to each other. In this state, the liquid silicon is injected through the gate formed in the mold.

According to the present invention, when liquid silicone is injected through the gate of the mold, the liquid silicon flows through the gate and flows into the gap between the gum connecting portion of the denture made of acrylic resin and the mold.

 When the liquid silicone is injected as described above, the liquid silicone is formed by thermal curing and photopolymerization so as to be integrated with the acrylic resin.

 According to the present invention, when the molding is completed by the molding process, the mold is separated and the denture is separated, so that the soft silicone is drawn out in a state of being integrated with the gum of the denture.

In the denture thus drawn out, liquid silicone is injected into the gingival joint, and the barb formed for the joining portion and the gate of the upper and lower dies may be cleanly removed.

On the other hand, according to the present invention, when the polishing depth is set to 0.2 to 2 mm in the polishing step, silicon is not thick, so that it is possible to prevent dentures from being loosely bonded to the gums, So that the pain can be prevented from occurring in the gums.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modification is possible.

Accordingly, the spirit of the present invention should be understood only in accordance with the following claims, and all equivalents or equivalent variations thereof are included in the scope of the present invention.
