Abstract

The embodiment of the invention discloses a processing method for an oral cavity all-ceramic restoration. The method comprises the following steps that a, scanning data of a preparation body is acquired and then reconstructed into three-dimensional data; b, three-dimensional data of the all-ceramic restoration is designed in the three-dimensional data of the preparation body; c, the three-dimensional data of the all-ceramic restoration is imported into three-dimensional control software of an ultrashort pulse laser, according to the three-dimensional data of the all-ceramic restoration, a cutting trajectory is planned, working parameters of the ultrashort pulse laser are adjusted, and the ultrashort pulse laser is driven to conduct cutting according to the cutting trajectory so as to obtain the all-ceramic restoration. According to the processing method, by acquiring the three-dimensional data of the all-ceramic restoration and controlling the ultrashort pulse laser, manufacturing is conducted, the all-ceramic restoration can be precisely processed, the sintering process is not needed, the manufacturing time can be effectively shortened, the damage to the all-ceramic restoration inthe sintering process is avoided, the product quality of the all-ceramic restoration can be improved, and the service life is prolonged.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of processing an oral all-ceramic restoration, in particular to a processing method for an oral all-ceramic restoration. Background technique [0002] All-ceramic teeth, also known as all-ceramic crowns, are porcelain restorations that cover the entire surface of the crown and do not contain a metal inner crown. Since the inner crown is no longer made of metal, it is made of high-strength porcelain material similar to the color of the tooth, so it is more beautiful than the metal-based porcelain restoration, and its translucency is similar to that of natural teeth. simulation effect. [0003] In recent years, with the rapid development of science and technology and the continuous improvement of people's living standards, people have higher and higher requirements for the appearance of teeth, and all-ceramic restorations have become the preferred restoration method for most patients...
