Embodiment Construction

[0043] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] see figure 1 , a virtual articulator design method for functional occlusal surfaces of dental crowns and bridges of the present invention, comprising the following steps:

[0045] 1) Use the mandibular movement trajectory analyzer to record the three-dimensional trajectory information of the characteristic movement of the mandible during the individual chewing movement;

[0046] 2) Register and fuse the working coordinate system of the mandibular motion trajectory analyzer with the three-dimensional scanning coordinate system of the dentition;

[0047] 3) Create the CAD data of the crown and bridge restoration of the static cross-occlusal teeth;

[0048] 4) Establishment of virtual occlusal automatic detection and automatic occlusal adjustment platform;

[0049] 5) Virtual occlusal automatic detection;

[0050] 6) Automatic ...

Abstract

The invention relates to a virtual articulator design method for functional occlusal surfaces of dental crowns and bridges. Registration and fusion of the mandibular motion trajectory analyzer working coordinate system and the three-dimensional scanning coordinate system of the dentition; 3) Create CAD data of crown and bridge restorations of static cusp cross-occlusal teeth; 4) Establishment of virtual occlusal automatic detection and automatic occlusal adjustment platform ;5) Automatic virtual occlusal detection; 6) Automatic virtual occlusal adjustment to create dental crown and bridge CAD data with functional occlusal surfaces. By simulating each person's personalized chewing characteristic movement, the present invention realizes accurate and quantitative virtual occlusal automatic detection and automatic virtual occlusal adjustment, and avoids repeated grinding when patients try on prosthetics, thereby greatly improving the accuracy and efficiency of prosthetic production .

Description

technical field [0001] The invention relates to a dental crown and bridge prosthesis CAD, in particular to a virtual articulator design method for functional occlusal surfaces of dental crowns and bridges. Background technique [0002] The articulator is a commonly used auxiliary device in the design and fabrication of clinical restorations. It can simulate the movement of the human jaw, and the restorations made with the aid of the articulator are more likely to meet the individual needs of the patient. [0003] Dental restoration CAD / CAM (Computer Aided Design / Computer Aided manufacturing, computer-aided design and computer-aided manufacturing) technology is a highly automated restoration design and processing technology. In addition to the high precision and high efficiency of industrial automation, this type of system In addition to its unique features, it also integrates a large number of medical experts' knowledge and clinical experience into the CAD software, which c...
