Problems solved by technology

[0002] At present, the restoration of damaged teeth is mostly to extract the damaged teeth and install artificial teeth on the gums. In the prior art, the means of fixing artificial teeth on the gums are mostly achieved by the combination of implants and abutment accessories. , when the existing abutment accessories are combined with implants to fix the artificial teeth on the gums, there is a defect of poor firmness, which cannot guarantee the long-term use of the artificial teeth, and the artificial teeth are easy to fall off from the gums

Embodiment 1

[0037] see Figure 1-6 , this embodiment provides a high-stability core-shaped abutment with adjustable orientation and platform transfer, which is used in the Department of Stomatology to realize a stable connection between teeth and implants, including an abutment body 10, and the abutment body 10 includes sequentially connected The first tapered portion 101, the protruding portion 102, the second tapered portion 103, the limiting portion 104 and the positioning portion 105, the first tapered portion 101 is used to increase the contact area with the teeth and improve The stability of teeth and implants, while providing platform transplantation to enhance the growth of bone tissue and soft tissue, the raised portion 102 is used to increase the level of compensation to reduce the contact gap with the implant, the second tapered portion 103 Fitted on the inside of the implant to increase the connection tightness, the limiting part 104 is embedded inside the implant to improve t...

Embodiment 2

[0044] see Figure 7 , the present embodiment provides a central screw 20, including a screw body 204, a third tapered portion 203 arranged at one end of the screw body 204, and an end of the third tapered portion 203 away from the screw body 204 The elongated part 201 of the screw body 204 is provided with a screw thread 205 on the outer wall of one end away from the third tapered part 203, and the screw body 204 can pass through the first through hole 108, the second through hole 109 and the third through hole. The hole 110 is connected to the inner wall of the implant using the thread 205, and the third tapered portion 203 fits on the inner wall of the second through hole 109. Since the second through hole 109 is a tapered hole structure, the third tapered portion When 203 fits with the inner wall of the second through hole 109, the self-rotation of the screw body 204 can be avoided, the screw body 204 can be prevented from loosening, and the stability of the central screw ...

Abstract

The invention provides an orientation-adjustable platform-transferred high-stability nuclear-shaped abutment, and belongs to the technical field of dental restoration. The abutment comprises an abutment body, the abutment body comprises a first conical part, a protruding part, a second conical part, a limiting part and a positioning part which are sequentially connected, and the first conical part is used for increasing the contact area with teeth. The convex part is used for increasing horizontal compensation so as to reduce a contact gap with an implant, the second conical part is attached to the inner side of the implant, the limiting part is embedded into the implant, and the positioning part is used for being inserted into the implant so as to achieve alignment of the abutment body. Compared with the prior art, the embodiment of the invention can greatly improve the connection firmness between the tooth and the implant, and has the advantages of adjustable abutment orientation, accurate alignment, simple structure and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of tooth restoration, in particular to a high-stability core-shaped abutment and a central screw with adjustable orientation and platform transfer. Background technique [0002] At present, the restoration of damaged teeth is mostly to extract the damaged teeth and install artificial teeth on the gums. In the prior art, the means of fixing artificial teeth on the gums are mostly achieved by the combination of implants and abutment accessories. , when the existing abutment accessories are combined with the implant to fix the artificial tooth on the gingiva, there is a defect of poor firmness, which cannot guarantee the long-term use of the artificial tooth, and the artificial tooth is easy to fall off from the gingiva. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a...
