Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-2, the high-permeability zirconia all-ceramic denture provided by the present embodiment includes an implant abutment 10 and a denture body, wherein the top end of the implant abutment 10 can be implanted into the alveolar bone, and the top end of the implant abutment 10 is exposed outside the alveolar bone, the denture body is detachably mounted on the implant abutment 10, and in order to improve the stability of the connection between the implant abutment 10 and the alveolar bone, the outer side surface of the implant abutment 10 is provided with a thread 11 protruding from the implant abutment 10.

In this embodiment, in order to facilitate the installation and the detachment of the denture body, the denture body includes an all-ceramic body 21 and a connection seat 22, a groove 211 is provided at the bottom of the all-ceramic body 21, and the top end of the connection seat 22 is inserted into the groove 211 and is bonded with the all-ceramic body 21. In order to install the prosthesis main body, the bottom of the connection seat 22 is provided with an external thread 221, the top surface of the implant abutment 10 is provided with a mounting groove 12, the side wall of the mounting groove 12 is provided with an internal thread 121, and the internal thread 121 is matched with the external thread 221, so that the connection seat 22 can be in threaded connection with the implant abutment 10 through the external thread 221. Thereby making the denture body detachable. In addition, in order to reduce the processing cost, the inside of the connecting seat 22 is provided with a glue injection hole 23, the glue injection hole 23 is arranged along the axial direction of the connecting seat 22 and penetrates through the connecting seat 22, the top end of the connecting seat 22 is further provided with a plurality of through holes 231 communicated with the glue injection hole 23, and the through holes 231 are arranged along the radial direction of the connecting seat 22 and penetrate through the connecting seat 22.
