Description

Dental prosthesis {Dental prosthesis}

The present invention relates to a dental incisor prosthesis, more specifically, to improve the structure of the prosthesis for fixing the artificial tooth in place of the function of the missing tooth, even if prolonged use, the artificial tooth does not swing back and forth or easily separated and removed during the procedure It relates to a dental incisor prosthesis that prevents the nerves of the tooth from being damaged.

In general, the function of teeth has a pronunciation and aesthetic function in addition to chewing function to crush food. When these teeth are lost, problems such as inadequate intake of food may cause nutritional problems, or the surrounding teeth of the lost teeth may be inclined, resulting in inconsistent occlusal teeth. In addition, since human teeth are no longer newly formed even after the teeth are replaced with permanent teeth, new treatments are no longer needed. Known.

Dental prosthesis treatment is divided into crown, bridge, denture, esthetic prosthodontics and implant prosthesis. It is a treatment that restores function, shape, and aesthetics simultaneously by connecting the processed tooth to the lost part by supporting the tooth.

Conventional dental prostheses are provided with coupling protrusions that are separately coupled and fixed to adjacent teeth adjacent to the lost tooth when one or more teeth of one of the front teeth are lost, and a fixing piece in which a fitting protrusion is integrally formed on one side, and fitting of the fixing piece. The fitting grooves inserted into and fixed to the protrusions are formed on the left and right sides and are composed of artificial teeth which are treated between adjacent teeth.

In order to perform the conventional dental prosthesis configured as described above, first, a coupling hole into which a coupling protrusion can be inserted is formed on a rear surface of an adjacent tooth, and when the coupling protrusion is inserted into the coupling hole, fixing pieces are fixed to respective edges of the adjacent tooth. . In the above state, when the fitting grooves are fitted into the fitting protrusions, respectively, the artificial teeth are positioned between adjacent teeth, and the procedure is completed.

The conventional dental prosthesis has the advantage that the artificial tooth can be replaced in place of the lost tooth, but the conventional coupling protrusion is formed to protrude outwards on the front of the body of the fixing piece. Therefore, in order to fix the fixing piece to the adjacent teeth, a coupling hole is formed at a position corresponding to the engaging projection of the fixing piece, that is, the rear surface of the adjacent tooth. In this case, because of the characteristics of the front teeth, the thickness of the left and right, and the front and rear thickness is thin, the risk of touching the nerve in the process of forming a coupling hole on the back.

In addition, the engaging projection of the conventional fixing piece is formed to protrude to the front, the engaging hole is also formed on the back of the adjacent teeth has a structure that is coupled to each other. Therefore, when using artificial teeth for a long time, there are various problems such as the artificial teeth shaking back and forth or easily separated and dropped.

The present invention has been made in view of the above-mentioned problems, and even if used for a long time by improving the structure of the prosthesis for fixing the artificial teeth to replace the function of the teeth, the artificial teeth are not shaken back and forth or easily separated and removed during the procedure To provide a dental incisor prosthesis to prevent damage to the nerves.

In the present invention, a known coupling protrusion formed on the fixing piece is formed to protrude upward and downward at regular intervals on the inner side of the fixing piece, and two coupling holes are formed on the side of the adjacent tooth so that the coupling protrusion is inserted and fixed up and down. It is the basic characteristic in the technical constitution.

According to the present invention, a prosthesis for fixing an artificial tooth that replaces the function of a tooth, that is, a coupling protrusion of the fixing piece protrudes from the side, and a coupling hole into which the coupling protrusion is inserted is formed on the inner side of the adjacent tooth. Therefore, the fixing piece and the adjacent teeth are coupled to each other through the side, so even after long-term use of artificial teeth, they do not shake up and down and are not easily separated or dropped.

In addition, when the coupling hole is formed on the side of the adjacent teeth, the left and right thickness is large, so there is little risk of touching the nerve, and the coupling hole can be formed deeper and can be safely operated.

In addition, since the fixing piece is positioned between the artificial tooth and the adjacent tooth, and the artificial tooth is coupled and fixed between the adjacent teeth through the fixing piece, the artificial tooth is effective in that it is not easily separated from left, right, up and down, and back and forth.

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

1 is a front view showing the state of the dental prosthesis according to the present invention is applied to the front teeth of the upper teeth (upper teeth), Figure 2 is a state in which the dental prosthesis according to the present invention is performed on the front teeth of the lower teeth (lower teeth) It's a front view.

Dental prosthesis of the present invention is also provided with a coupling protrusion (220) which is coupled to each of the adjacent teeth (100, 100a) adjacent to the lost tooth when one or more teeth of the front tooth is lost and the fitting protrusion (210) ) Is formed integrally with the fixing piece 200, and the fitting groove 310 is inserted and fixed to the fitting protrusion 210 of the fixing piece 200 is formed on the left and right side and the procedure between the adjacent teeth (100, 100a) It is made of an artificial tooth (300).

However, the present invention is to be able to perform a more effective procedure, which protrudes up and down the known coupling protrusion 220 formed on the fixing piece 200 at a constant interval on the inner surface of the fixing piece as shown in Figure 1 and Figure 2 It is formed, the adjacent teeth 100, 100a side is configured to form two coupling holes 400 up and down so that the coupling projection 220 can be inserted and fixed.

When the coupling hole 400 is processed on the side of the adjacent teeth 100, 100a, the upper inclination is inclined upwardly toward the gums, and the lower inclination is inclined downwardly toward the gums, 45 ° It has an angle of inclination.

Figure 1 shows the state that is performed when one of the incisors of the incisor (upper teeth) is lost to complete the artificial tooth 300 suitable for the operator through the known work process to process the incisor. After the fixing piece 200 having two coupling protrusions 220 protruding up and down on the inner side, and then adjacent to the teeth (100) (100a) side so that the coupling protrusion 220 can be inserted, The two coupling holes 400 are then machined.

Inserting and fixing the coupling protrusion 220 to the coupling hole 400 in the above state, and inserting the fitting groove 310 into the fitting protrusion 210, the artificial tooth 300 is between the adjacent teeth (100, 100a) As described above, the dental prosthesis through the side coupling structure as described above is not shaken back and forth or easily separated even after long-term use.

Figure 2 shows a state that is performed when the two incisors of the lower teeth (lower teeth) is to be treated, which is also provided with a fixing piece formed with a coupling protrusion 220 up and down on the inner side of the fixing piece 200, the coupling described above The protrusion 220 is inserted into the coupling hole 400 is inserted into the adjacent teeth 100, 100a side to be processed up and down. Thereafter, the coupling protrusion 220 is coupled to the coupling hole 400, and the insertion groove 310 is inserted into the fitting protrusion 210 of the fixing piece 200 so that the artificial tooth 300 is disposed between the adjacent teeth 100 and 100a. The dental prosthesis will not shake back or fall off easily even after long term use.
