Embodiment 1

[0024] A method for making a digitally mirrored CAD / CAM temporary tooth, comprising the following steps:

[0025] (1) Collect basic patient information

[0026] The basic information includes the STL data of the intraoral scan, the DICOM data generated by the CBCT, and the photo of the patient’s face with a toothy smile on the front and the photo of the front tooth with a black background in the mouth. There are 8 teeth in total from the molar to the left first premolar.

[0027] (2) Obtain the digital image of the patient's facial smile, use the facial digital smile design (DSD) to conduct aesthetic analysis and design on the front teeth with teeth in the mouth, and obtain the shape and related parameters of the missing teeth. The specific process is as follows:

[0028] Obtain the digital image of the patient's facial smile, import the photo of the patient's frontal toothy smile into the software that can do DSD, such as PPT, and draw the patient's facial midline, dental mi...

Abstract

The invention discloses a manufacturing method of digital mirrored CAD / CAM transitional teeth. The method comprises the following steps that basic information of a patient is collected; aesthetic analysis and design are carried out on anterior teeth in the mouth by using digital smile design (DSD); the three-dimensional form of opposite-side homonymous teeth is extracted, and the three-dimensionalform of mirrored teeth is obtained; a CAD model of the digital mirrored transitional teeth is designed; the position of an implant is designed, and then lingual surface hole positions of the transitional teeth are determined; the CAD model, where the lingual surface hole positions are designed, of the digital mirrored transitional teeth is processed to prepare the digital mirrored CAD / CAM transitional teeth. According to the method, the computer graphic image processing technology is adopted, an aesthetic principle is comprehensively applied, and a novel method for visual oral aesthetic analysis and design is carried out so that the problems that in a traditional manufacturing method, the transgingival contour is uncontrollable, disinfection and polishing are not easy, and the time for operating beside a chair is long can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of temporary denture models, in particular to a method for making digital mirrored CAD / CAM temporary teeth. Background technique [0002] Obtaining the ideal gingival margin shape is the focus and difficulty of implant aesthetic restoration. In order to obtain a scallop-like appearance of the gingiva, the use of temporary teeth for gingival shaping is a common method in clinical practice. The traditional process of making temporary teeth is as follows: take an impression, pour the model, use resin to build up the temporary tooth manually on the model, polish it and put it in the patient's mouth, and then adjust the temporary tooth continuously according to the shape of the patient's gums until the obtained Ideal transgingival shape. There are many disadvantages in this traditional process of making temporary teeth: 1) manual plasticizing of temporary teeth, the contour of the gingival penetration is uncont...
