Embodiment 1

[0040] Figure 1~5 It is a specific embodiment of using the present invention to repair a case of missing the first bicuspid tooth on the upper left.

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

[0042] The integral support includes a wing plate 1, a connecting body 2, a base profile extension 4 formed by the extension of the upper part of the wing plate, and an undercut lower portion 5 formed by the extension of the lower part of the wing plate.

[0043] The wing plate 1 is located at the two ends of the integr...

Embodiment 2

[0056] Figure 6-10 It is a specific embodiment of using the present invention to repair the missing first molar on the left.

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

[0058] The material for making the integral stent can be any one of precious metals, non-precious metals, zirconia, alumina, synthetic diamonds, and corundum.

[0059] Since the first molars have to bear greater occlusal force, and the aesthetic requirements of the second bicuspids and second molars as abutments are lower, in this embodiment, the area of ​​the wing plate joint face and edge part is enlarged. , Increase the base profile extension 4 to improve retention. In addition, two bolted protrusions 3 with opposite protrusion directions are formed on the connecting body, which not only enlarges the bonding area with the bolted pontic tooth, prevents the bolted pontic tooth from loosening, twisting, r...

Embodiment 3

[0062] Figure 11-15 It is a specific embodiment of using the present invention to simultaneously repair the missing cases of the first molar of the second upper left bicuspid.

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

[0064] When restoring the second bicuspid first molar at the same time, the requirements for the abutment are higher, except for the above-mentioned expansion of the area of ​​the wing plate joint face and edge part, the increase of the base shape extension, and the expansion of the wing plate covering the non-functional area of ​​the joint 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 distribution of stress....

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 toothis 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 dental restoration for fixed restoration of missing teeth and a manufacturing method thereof. Background technique [0002] In today's rapid development of human society, people's outlook on life and aesthetics has also improved. In people's daily life, teeth are very important. The lack of teeth not only affects people's appearance, but also affects the chewing function and language function of the mouth. Most of the tooth loss is caused by the removal of trauma, dental caries, root canal treatment failure, periodontal disease and other reasons. The alveolar bone of missing teeth will undergo disuse bone resorption because there is no physiological stimulation such as chewing. In order to maintain the biological width, the gums will also shrink, which will eventually lead to the overall defect of the soft and hard tissues; moreover, the adjacent teeth will be missing after the ...
