All-ceramic denture grinding system and method for fabricating denture

Abstract

The invention relates to an all-ceramic denture grinding system and a method for fabricating a denture. By adopting the system, a denture briquette is fabricated into the denture. The system comprises a bracket, and a Z-axis displacement mechanism, X-axis displacement mechanisms, Y-axis displacement mechanisms and a grating ruler which are arranged on the bracket, wherein the Z-axis displacement mechanism comprises a Z-axis movement seat; the Z-axis movement seat is used for fixing the denture briquette and a temporary metal denture; two groups of X-axis displacement mechanisms and two groups of Y-axis displacement mechanisms are oppositely arranged on two sides of the Z-axis displacement mechanism respectively; a tool component for depicting the temporary metal denture and cutting the denture briquette is arranged on each group of Y-axis displacement mechanisms; each group of Y-axis displacement mechanisms pushes the tool component to move along the Y-axis direction; each group of X-axis displacement mechanisms is connected with the corresponding tool component, and pushes the tool component to move along the X-axis direction; and the grating ruler is used for recording displacement data of the tool component moving along the Y-axis direction and the X-axis direction in real time.

Description

technical field [0001] The invention relates to an all-ceramic denture grinding system and a method for making dentures. Background technique [0002] Tooth defect is a common human disease. In addition to tooth defect, tooth deformity is also a problem that cannot be ignored. With the improvement of living conditions, people pay more and more attention to dental health, and have higher requirements for the appearance of teeth. Dentures Restoration is the only way to solve these problems at present. At present, hand-made dentures are still a typical oral restoration method for domestic doctors. Generally, metal restorations are cast into metal restorations, considering the appearance, and ceramics are baked on metal dentures, and finally porcelain dentures are obtained. The production process of dentures is all manual operation, the process is cumbersome, the efficiency is low, the precision is not high, and the cycle is long. In addition, the porcelain teeth have poor chewi...

AI Technical Summary

Problems solved by technology

[0005] 1: Establishing a CAD model of a denture restoration requires expensive measuring equipment and the development of special denture restoration design software. It may also require various dental databases. The technology is complicated and the cost is high. It is economically difficult for most ordinary patients in our country. bear

[0006] 2: The surface of the denture restoration is a typical engraving surface, but the shape of the denture grinding tool (that is, the diamond grinding needle) is very different from the traditional spherical tool and cylindrical tool. It is a conical tool with a blunt top, which is difficult to Accurately calculate the tool point trajectory of the tool during grinding, which will lead to a decrease in the manufacturing accuracy of the all-ceramic restoration, or even failure of the restoration;

[0007] 3: The driving power of the diamond grinding needle rotation during denture grinding is driven by a servo motor. When grinding high-hardness ceramic materials, due to the speed limitation of the motor, it is difficult to grind at high speed, and the processing efficiency and denture surface quality are limited.
