The embodiment of the invention provides a method and equipment for trimming a tooth model. The method comprises the following steps: acquiring a to-be-trimmed tooth model, a preset selection radius and a preset wax pattern height; obtaining a finishing base point on the visible surface of the to-be-trimmed tooth model, and constructing a spherical area with the radius equal to the preset selection radius by taking the finishing base point as a sphere center; identifying a visible point in the spherical area on the to-be-trimmed tooth model; then moving the visible point based on the preset wax pattern height to add or erase the wax pattern in the spherical area to generate a new tooth model; and finally taking the new tooth model as a to-be-trimmed tooth model, and repeating the steps until the tooth model meeting the preset requirements is generated. According to the method, a doctor can digitally trim the tooth model according to own requirements, and then directly manufactures thesolid tooth wax pattern based on the trimmed tooth model, so that the cumbersome subsequent manual filling is avoided.
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...
