Method for processing ultra-thin cast porcelain laminate veneer capable of preventing tooth grinding

Abstract

The invention relates to the field of dental prosthesis, in particular to a method for processing ultra-thin cast porcelain laminate veneer capable of preventing tooth grinding. The method comprises the following steps: a three-dimensional scanner is adopted to scan a dental cast, a three-dimensional stereoscopic image is formed, an ultra-thin veneer with the thickness of less than 0.5 mm is designed on the virtual image, after the ultra-thin veneer is designed, data is output to a 3D (three-dimensional) resin wax forming machine, the ultra-thin veneer is formed in the manners of resin-spraying, irradiation curing and printing, and then the formed resin wax pattern is subjected to embedded casting, grinding adjustment, try-in and glazing. Compared with the prior art, the method adopts a computer to design, and the conventional hand-made wax pattern is replaced by the resin wax pattern processed by the digital resin wax spraying, irradiation curing and printing processing, so that fabrication of porcelain laminate veneer with the thickness of less than 0.5 mm is realized. An aesthetic seeking patient with discolored teeth does not need tooth grinding and can receive tooth-whitening treatment without hurting teeth.

Description

[0001] technical field [0002] The invention relates to the field of dentures, in particular to a processing method for an ultra-thin cast porcelain veneer without grinding teeth. [0003] Background technique [0004] The existing porcelain veneer technology needs to have a thickness of more than 0.7 mm due to the manual operation of the wax pattern, the strength of the material, and the manufacturing process and technology. This will obviously change the protrusion of the teeth and cause protrusion deformity. Therefore, it is necessary to grind the teeth to eliminate this effect, so the damage to the teeth is large. [0005] Contents of the invention [0006] In order to overcome the deficiencies of the prior art, the invention provides a method for processing an ultra-thin cast porcelain veneer without grinding teeth. The thickness of the cast porcelain veneer obtained by the method of the present invention is less than 0.5 mm, and the thickness can be as thin as 0....

AI Technical Summary

Problems solved by technology

[0004] The existing porcelain veneer technology requires a thickness of more than 0.7 mm due to manual operation of the wax pattern, strength of the material, manufacturing process, and technology, which will significantly change the protrusion of the teeth and cause protrusion deformity

Therefore, it is necessary to grind the teeth to eliminate this effect, so the damage to the teeth is great.
