Personalized transfer composite abutment

Abstract

The invention relates to a personalized transfer composite abutment which comprises a cylindrical transfer abutment body, a screw is inserted into the transfer abutment body, the lower end of the screw is in threaded connection with an implant, a plurality of groups of notches are concavely formed in the peripheral surface of the upper end of the transfer abutment body, a porcelain tooth is in a crown shape, the inner cavity of the porcelain tooth is matched with the shape of the upper end part of the transfer abutment body, the inner wall of the porcelain tooth is coated with a resin adhesive, and when the porcelain tooth is buckled at the upper end part of the transfer abutment body, the resin adhesive enters each group of notches and is cured to form an adhesive layer. According to the technical scheme, the filling amount of the resin adhesive is increased, the resin adhesive forms an adhesive layer in each group of notches, and the adhesive layer further improves the bonding strength between the porcelain tooth and the transfer abutment body, so that the porcelain tooth is not easy to loosen in the later length use of a patient, the discomfort of the patient wearing the porcelain tooth is reduced, and the service life of the porcelain tooth is prolonged.

Description

technical field [0001] The application relates to the field of denture implantation, in particular to a personalized transfer composite abutment. Background technique [0002] Dental implants, also known as artificial tooth roots, are structurally divided into three parts: abutment, implants and screws. During the implantation process of dental implants, the dentist first surgically implants the implant into the missing tooth In the alveolar bone, after the implant and the alveolar bone heal, the conversion abutment is connected to the implant, and the porcelain crown is buckled and fixed on the conversion abutment to complete the implantation process of the denture. [0003] During the implantation process of the denture, after the implant and the alveolar bone are integrally fixed and the gingiva is shaped with the help of the healing abutment, it is necessary to install the porcelain teeth with the help of the transfer abutment. Generally, the upper part of the transfer ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: in the installation process of the existing dentures, after the fixed connection between the transfer abutment and the implant is completed, it is necessary to connect the sintered porcelain tooth with the transfer The upper end of the abutment is fixed and installed. The formed porcelain teeth are usually coated with resin adhesive inside and then fastened to the upper end of the transfer abutment. The inner surface of the porcelain tooth and the outer surface of the transfer abutment There is a gap between them. In order to improve the integrity between the porcelain tooth and the transfer abutment, the size of the gap is mostly small, so that the resin adhesive filled inside the porcelain tooth is less. During the long-term use of the patient , the bonding strength between porcelain teeth and transfer abutment tends to decrease with the increase of chewing times, so there is room for improvement
