A design and fabrication method for precise bionic aesthetic restorations

Abstract

The invention relates to a design and production method of a precise bionic aesthetic prosthesis. The method comprises the following steps of (1) scanning teeth and adjacent teeth requiring aestheticrestoration; (2) designing the outer surface three-dimensional form of the aesthetic prosthesis by CAD software; printing the outer surface three-dimensional form into an aesthetic diagnosis model; (3) making a printing mold by using the model in the step (2); fully injecting tooth color temporary crown flowing resin; obtaining the aesthetic form identical to the CAD design; (4) after a patient confirms the aesthetic form, obtaining the outer surface data of the prosthesis through three-dimensional scanning; (5) performing three-dimensional scanning again after the quantitative tooth body preparation; obtaining the inner surface data of the prosthesis; (6) using the tooth or gum which is not subjected to tooth body preparation as a simultaneous region for registering the data on the innerand outer surfaces of the prosthesis onto the same coordinate system to complete the design; (7) performing 3D printing on the bionic color tooth preparation body substitutional form. The design and production method has the advantages that the individual bionic form and the color predictable performance of a porcelain aesthetic prosthesis can be improved; the precise realization of the existing aesthetic form is ensured.

Description

Technical field [0001] The invention relates to a dental restoration production, in particular to a design and production method of a precise bionic aesthetic restoration. Background technique [0002] At present, although the design and production of dental restorations are completed through CAD design, the precise performance of the aesthetics of the dental restorations is inaccurate, and the color effect is not clear. At the same time, the time and energy spent on personalized bionics is huge for the three parties of doctors, technicians and patients. , Which not only increases the difficulty of production, but also brings adverse effects to patients. Summary of the invention [0003] In order to overcome the above shortcomings, the present invention provides a method for designing and manufacturing accurate bionic aesthetic restorations, which can improve the predictability of the personalized bionic shape and color of all-ceramic aesthetic restorations, ensure the accurate re...
