Wear-resistant combined all-ceramic false tooth and processing technology

Abstract

The invention relates to the technical field of false teeth and processing thereof, in particular to a wear-resistant combined all-ceramic false tooth and a processing technology thereof.The processing technology comprises the steps that S1, preparing a model, specifically, a human body is comprehensively examined, and an impression is obtained; s2, model scanning; s3, dental crown design: using professional design software to complete form design of a dental top crown and a dental middle seat; s4, carrying out CAM processing; s5, cleaning the module; s6, dyeing the module; s7, drying and sintering; s8, repairing the restoration body; s9, performing sand blasting and glazing; s10, processing a gingival seat: calculating by using professional software, typesetting a tool path, quickly processing a high-precision gingival seat by using a professional milling machine, and pre-embedding a medical screw in the gingival seat; and S11, assembling the all-ceramic false tooth: firstly performing threaded connection on the tooth middle seat and the medical screw, and then assembling the tooth top crown and the tooth middle seat into a whole. The replacement process of the all-ceramic false tooth can be simplified, and the repair cost of replacing the all-ceramic false tooth is reduced.

Description

technical field [0001] The application relates to the technical field of dentures and their processing, in particular to a wear-resistant combined all-ceramic denture and its processing technology. Background technique [0002] Dentures are what people often call "false teeth". Just like "prosthetic legs" and "prosthetic limbs" are called "prosthetic limbs", "dentures" mean teeth that perform "duties" for human beings. Dentures are medically the general term for restorations made after partial or complete tooth loss of the upper and lower jaws. There are two types of dentures: removable and fixed. Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves, while removable dentures (commonly known as "movable dentures") can be easily taken and worn by patients. [0003] All-ceramic dentures are new crown restorations that have emerged in recent years. They are made of castable new ceramic materials. They are superior to metal-cerami...

AI Technical Summary

Problems solved by technology

[0004] But existing combined all-ceramic dentures also have some defects, for example: the material strength of most combined all-ceramic dentures is low, and porcelain cracking occurs easily when occlusal, and the service life is short; 2, combined all-ceramic dentures are mostly Multiple single pieces are integrally cast porcelain. Although the all-ceramic dentures are connected together, when one of the all-ceramic dentures is damaged and cracks occur, the cracks will easily extend along the all-ceramic dentures to the adjacent all-ceramic dentures, and there are defects in use.

[0005] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: after the all-ceramic denture is damaged, it needs to be reworked to replace a new all-ceramic denture, the replacement process is cumbersome, and the cost of replacing the whole all-ceramic denture is relatively high
