Abstract

Embodiments of the present invention provide a method and equipment for trimming a tooth model, wherein the method first obtains the tooth model to be trimmed, the preset selection radius, and the preset wax-up height; and then obtains the trimming on the visible surface of the tooth model to be trimmed Base point, with the modified base point as the center of the sphere, construct a spherical area with a radius equal to the preset selection radius; then identify the visible points on the tooth model to be modified within the spherical area; then move the visible points based on the preset wax-up height to Add or erase wax patterns in the spherical area to generate a new tooth model; finally, use the new tooth model as the tooth model to be modified, and repeat the above steps until a tooth model that meets the preset requirements is generated. This method allows doctors to digitally trim the tooth model according to their own needs, and then directly manufacture a solid tooth wax-up based on the trimmed tooth model, avoiding the tediousness of subsequent manual filling.

Description

technical field [0001] The invention relates to the field of oral implant technology, in particular to a method and equipment for trimming a tooth model. Background technique [0002] In recent years, with the clinical promotion of oral implant technology and the improvement of people's requirements for oral health, more and more patients choose to have implant restoration treatment for missing teeth. Oral implant guidance technology can assist doctors to accurately place implants according to the predetermined implant position, and can minimize the risk of accidental damage to adjacent important anatomical structures. Implant guide technology is widely used in oral implant guidance technology. Among them, the use of computer-aided design and manufacturing method (also known as CAD / CAM method) to design and manufacture implant guides based on patient medical image data is the direction and trend of the development of dental implantology. [0003] In the process of designin...
