Abstract

The invention relates to the technical field of dental restoration, and discloses a full-digital restoration method of an oral zirconia crown, which comprises the following steps: pre-scanning teeth to obtain an original form; carrying out prosthesis design through Exocad dental design software; cutting a temporary resin crown on a lathe according to a design file; adjusting the design draft according to the clinical try-on result of the temporary crown, or re-scanning the temporary crown after clinical adjustment, and updating the design draft; and according to the final design file, manufacturing a final restoration through a 3D colloidal deposition process. Through the clinical verification effect of the temporary crown, the clinical zero grinding of the final prosthesis can be realized. The method is novel in design and simple in process, and has the advantages of high digitization degree, short time consumption and high efficiency.

Description

technical field [0001] The invention relates to the technical field of dental restoration, in particular to an all-digital restoration method for oral zirconia crowns. Background technique [0002] With the development of computer and optical equipment, digital technology has been introduced into the field of dentistry, and dental treatment has become more accurate. Currently, digital technologies commonly used in dentistry include cone beam CT (CBCT), intraoral scanning, electronic facebow and virtual articulator, Digital Smile Design (DSD), Computer Aided Design and Computer Aided Manufacturing (CAD-CAM). However, the current digitization process represents a partially digitized workflow. In the clinical aspect, temporary crowns are usually handmade; in terms of manufacturing, due to the limitation of the optical properties of the material, the current state-of-the-art pre-sintered blank milling process based on computer numerical control (CNC) usually requires manual ven...
