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 method for making digital mirrored CAD / CAM temporary teeth, which comprises the following steps: collecting basic information of patients; using facial smile design (DSD) to perform aesthetic analysis and design on the front teeth showing teeth in the mouth; picking out the opposite side with the same name The three-dimensional shape of the tooth, obtain the three-dimensional shape of the mirror tooth; design the CAD model of the digital mirror temporary tooth; design the position of the implant and then determine the position of the lingual opening of the temporary tooth; design the CAD of the digital mirror temporary tooth with the position of the lingual opening The model is processed to make a digital mirror CAD / CAM temporary tooth. The present invention is a new method for visual oral aesthetics analysis and design by means of computer graphic image processing technology and comprehensive application of aesthetic principles, which can effectively solve the problems of uncontrollable gingiva contour, difficult disinfection and polishing, and long chairside operation time in traditional production methods.

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...
