Embodiment 1

[0040] Figure 1~5 It is a specific embodiment of utilizing the present invention to repair the case of missing upper left precuspid teeth.

[0041]The dental prosthesis of this embodiment includes an integral support and a bolted bridge tooth, and the described integral support is bonded and fixed with the abutment teeth on both sides adjacent to the missing tooth by means of enamel bonding; the said bolted bridge There is an inwardly recessed groove at the bottom of the body tooth, and the bolted pontic tooth is fixed by convex-convex bonding with the overall bracket through the groove, and forms a concave contact with the adjacent surface of the abutment tooth.

[0042] The overall support includes a wing plate 1, a connecting body 2, a base shape extension 4 formed by the extension of the upper part of the wing plate, and a lower concave part 5 formed by the extension of the lower part of the wing plate.

[0043] Said wing plate 1 is located at both ends of the overall su...

Embodiment 2

[0056] Figure 6-10 It is a concrete embodiment of utilizing the present invention to repair the missing case of the upper left first molar.

[0057] In this embodiment, the shape of the whole bracket forms a large S-shape in the posterior teeth area where aesthetic requirements are not high.

[0058] The material for making the whole stent can be any one of precious metal, non-precious metal, zirconia, aluminum oxide, artificial diamond and corundum.

[0059] Since the occlusal force to be borne by the first molars is relatively large, and the aesthetic requirements for the second bicuspids and the second molars as abutments are relatively low, in this embodiment, by enlarging the area of ​​the occlusal surface and the edge of the wing , increasing the shape extension part 4 of the base to improve the retention force. Moreover, two bolt protrusions 3 with opposite protruding directions are formed on the connecting body, which not only expands the bonding area with the bolte...

Embodiment 3

[0062] Figures 11-15 It is a specific embodiment of using the present invention to simultaneously restore the missing case of the left upper second premolar first molar.

[0063] The wing plate 1 of the integral bracket can be increased or decreased on the buccal-lingual side according to the aesthetic and functional requirements. In the case of low aesthetic requirements, the shape of the overall bracket forms a large S shape in the posterior teeth area.

[0064] When the second bicuspid first molar is restored at the same time, the requirements for the abutment are higher, except for the above-mentioned expansion of the area of ​​the occlusal surface and the edge of the wing plate, increasing the extension of the shape of the base, and enlarging the wing plate to cover the non-functional area of ​​the occlusal surface In addition to the basic operation of the area, abutment teeth are added to further improve the retention force, which is more conducive to the uniform distr...

Abstract

The invention provides a fission-typed dental prosthesis used for fixedly restoring lost tooth, comprising a whole bracket and a key way typed bridge tooth; the whole bracket is fixedly bonded to enamel used for abutment teeth at two sides of the lost tooth; the key way typed bridge tooth is fixedly bonded to the whole bracket in a zigzag way by a concave trough which is concave internally and arranged at the bottom of the key way typed bridge tooth, and forms a concave-surface contact with the adjacent surface of the abutment tooth. The preparation method of the fission-typed dental prosthesis of the invention is characterized in that non-functional area and inverted concave area of the abutment teeth at two sides of the lost tooth are analyzed on a model; wax-pattern is directly prepared on the copied original model; a suspension casting sprue is directly embedded so as to prepare the whole bracket by embedding, scorification and casting; subsequently, the key way typed bridge tooth is prepared. The fission-typed dental prosthesis needs no surgical operation, leads the manual denta prothesis to be firmly fixed on adjacent abutment teeth on the basis of no tooth-grinding or little tooth-grinding so as to bear the engaging force along all directions and uniformly disperse the force onto the abutment tooth, has good and natural appearance, good function, low cost, short treatment period, good fixing effect, and eliminates the black triangle area of adjacent teeth at the same time.

Description

technical field [0001] The invention relates to the field of dental hygiene, in particular to a split-type dental prosthesis for fixedly repairing missing teeth and a manufacturing method thereof. Background technique [0002] With the rapid development of human society today, people's outlook on life and aesthetics are also improving. In people's daily life, teeth are very important. The loss of teeth not only affects people's aesthetics, but also affects the chewing function and language function of the oral cavity. Tooth loss is mostly caused by trauma, caries, root canal treatment failure, periodontal disease and other reasons. The alveolar bone with missing teeth will undergo disuse bone resorption due to lack of physiological stimuli such as chewing, and the gums will also shrink in order to maintain the biological width, which will eventually lead to the overall defect of soft and hard tissues; moreover, the adjacent teeth will move toward the gap after tooth loss. ...
