Artificial tooth body having vertical type bone beam structure

Abstract

The invention relates to an artificial tooth body having a vertical type bone beam structure. The artificial tooth body comprises an abutment and an artificial gum, wherein the abutment is connected to the upper part of the artificial gum to allow an artificial crown to be connected; the artificial gum is formed by the erection of a plurality of vertical type bone beams; each vertical type bone beam is formed by longitudinal and horizontal connection of a supporting column which extends in the direction of bite force and a strengthening beam which is perpendicular to the bite force; and the extending direction of the supporting columns is the same as the transmitting direction of the bite force, so that when being borne with the bite force, the vertical type bone beam structure can maintain forward stress, bending force cannot generate, the supporting columns cannot be subjected to structural deformation because of stress, and the vertical type bone beam structure can improve the supporting intensity of the artificial tooth body. According to the artificial tooth body disclosed by the invention, the vertical type bone beam structure can bear the bite force in an initial stage of dental implant, and the artificial tooth body can immediately have the function of original teeth; and besides, osteocytes can grow in the inner part of the artificial tooth body, so that the artificialtooth body is merged with a tooth socket bone integrally.

Description

technical field [0001] The invention relates to artificial teeth, in particular to an artificial tooth with a vertical bone beam structure. Background technique [0002] Generally, when performing dental implant surgery, the implant must be embeded in the alveolar bone through surgery first, and it takes four to six months for the implant to osseointegrate with the alveolar bone, and then the implant is exposed in the oral cavity. After the abutment, the gums were sutured again, and the impression was taken after the gums healed a week later, and finally the artificial teeth were installed to complete the entire dental implant process. Or, in some ways, the implant and the abutment are directly integrated into one body, and after four to six months for the implant and the alveolar bone to undergo osseointegration, an impression is taken and artificial teeth are installed, such as a patent application in Taiwan, China No. M549056, No. I594734 and No. M546800 etc. belong to t...

AI Technical Summary

Problems solved by technology

However, the artificial tooth structure of the above-mentioned patent application does not have a special structure designed to support the occlusal force at the initial stage of dental implantation, and further assist the osseous fusion between the artificial tooth body and the alveolar; Problems such as low degree of body bone fusion and long fusion time

[0003] In order to improve the aforementioned problems of low degree of bone fusion and long fusion time, some people in the industry have further designed the bone beam structure of the artificial tooth root, and constructed holes through the bone beam structure for the entry of bone cells to assist the smooth progress of bone fusion, such as China Taiwan Patent Application No. I586334, and US Patents US8075312, US8899982, US9439738, US9707058 and US4492577 belong to this category

However, since the bone beam structure of the artificial tooth root does not straddle the hard cortical bone (Cortical bone), it cannot provide the supporting force at the initial stage of dental implantation, so it does not have the proper chewing function of the teeth at the initial stage of dental implantation; Moreover, the above-mentioned beams and columns used to construct the hole are irregular or inclined. When subjected to the occlusal force, the structure cannot maintain the positive stress and generate a bending moment force. Therefore, the microstructure is bent and deformed to cause the hole to collapse. On the contrary, it hinders the growth of bone cells; thus, it does not completely solve the problem of low degree of bone fusion and long fusion time, nor does it solve the problem of occlusal force support in the initial stage of dental implantation
