Embodiment Construction
[0027] The following is a detailed description in conjunction with specific embodiments, but the protection scope of the present invention is not limited by the specific embodiments.
[0028] like figure 1 As shown in the figure, the present invention provides a method for making a color-masking veneer in a full crown for oral restoration, and the steps are as follows:
[0029] S1. The digital three-dimensional model of the crown preparation can be obtained by using the oral scanner for the abutment preparation with the shoulder trimmed; the gypsum model of the crown restoration preparation can also be prepared by traditional impression taking, and then the crown restoration plaster can be prepared by scanning equipment. The volume model is converted 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 l...
