Embodiment Construction

[0027] The following will be described in detail in conjunction with specific examples, but the protection scope of the present invention is not limited by the specific examples.

[0028] Such as figure 1 As shown, the present invention provides a method for making an internal color-blocking veneer for oral restoration full crown, the steps are as follows:

[0029] S1. Obtain the digital 3D model of the crown preparation from the abutment preparation with the shoulder trimmed through the oral scanner; it is also possible to prepare a plaster model of the crown preparation by traditional impression taking, and then use the scanning equipment to prepare the plaster of the crown restoration Transform the solid model into a digital three-dimensional model;

[0030] S2. After importing the digital model into the oral computer-aided design (CAD) software to select the veneer restoration, draw the position of the veneer termination line on the labial side of the abutment teeth;

Abstract

The invention discloses a manufacturing method for a color masking veneer in an oral crown. The color masking veneer is manufactured on the basis of a digital optical scanner and denture design software and by utilizing a 3D printing technology; the color masking veneer is made of a low-transmittance ceramic material; and a veneer range of a digital abutment model is designed, positioning is conducted through 3D printing technology, then crystallizing is carried out, and then the color masking veneer is put in place on a prepared abutment tooth body to shield a discolored tooth body, so full-crown repair via a high-transmittance all-ceramic material is facilitated. According to the veneer manufactured by the method, the clinical application range of high-permeability ceramic materials such as glass ceramic is expanded, the strength of restoration is enhanced, and the doctor-seeing experience and satisfaction of a patient are improved.

Description

technical field [0001] The present application relates to the field of oral restorative treatment, in particular to a method for making a veneer. Background technique [0002] Porcelain-fused-to-metal crowns with color-shielding effects or modified porcelain crowns with low-permeability oxide ceramics and high-transparency are often used in the aesthetic area of ​​clinical oral restorative treatment. This type of full crown restoration consists of two different materials, and the combination of the two materials is completed through a special sintering process. Often the combined interface becomes the weak part of the crown restoration, resulting in clinical damage to the crown restoration. In addition, the strength of modified porcelain is far lower than that of oxide ceramics and glass ceramics. The surface strength of this type of restoration is not high. [0003] Porcelain-fused-to-metal crowns or low-transparency oxide ceramics plus high-transparency modified porcela...
