Problems solved by technology

[0002] At present, although the design and production of dental restorations are completed through CAD design, the precise performance of the aesthetic form of dental restorations is not accurate, and the effect of color representation is not clear. , which not only increases the difficulty of production, but also brings adverse effects to patients

Embodiment Construction

[0016] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] A method for designing and manufacturing a precise bionic aesthetic restoration of the present invention has the following steps:

[0018] 1) Scan the teeth and adjacent teeth that need to be aesthetically restored;

[0019] 2) Use CAD software to design the three-dimensional shape of the outer surface of the aesthetic restoration and print it into an aesthetic diagnostic model;

[0020] 3) Use the model in step 2) to make an impression, fill it with tooth-colored temporary crown flowing resin, and place it on the patient's current dentition. After the resin solidifies, take out the impression to obtain an aesthetic shape consistent with the CAD design;

[0021] 4) After the patient confirms the aesthetic shape, three-dimensional scanning obtains the data of the external surface of the restoration;

[0022] 5) Three-dimensiona...

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 the manufacture of a dental restoration, in particular to a method for designing and manufacturing 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 aesthetic form of dental restorations is not accurate, and the color effect is not clear. , Not only increases the difficulty of production, but also brings adverse effects to patients. Contents of the invention [0003] In order to overcome the above deficiencies, the present invention provides a design and manufacture method for precise bionic aesthetic restorations, which can improve the predictability of individual bionic shapes and colors of all-ceramic aesthetic restorations, ensure the accurate realization of known aesthetic shapes, and improve semi- The predictability and controllability of the color effect of the tran...
