METHOD FOR DIGITAL ARCHIVING AND MANUFACTURING OF DENTAL PROSTHETICS AND PROSTHESIS, AND TEACHING AND TRAINING FOR SAME

摘要

A method for digital archiving and manufacturing of dental prosthetics and a prosthesis, and teaching and training for same are provided. The method mainly includes the following steps: preoperative scanning: creating a first digital model file; optical positioning and turning treatment: creating a second digital model file from a turning process; physical model calculation: creating reversely an autologous crown model file of a patient; and fixed denture manufacturing: manufacturing, according to the second digital model file and the autologous crown model file, a fixed denture that meets needs of the patient, so that an inner layer structure of a crown of the fixed denture can be tightly bound to an abutment, and it may be decided to retain an original crown contour according to needs. A tooth model based on a teaching digital model file can be used for teaching and training of a trainee with the foregoing method.

主权项

1. A method for digital archiving and manufacturing of dental prosthetics and a prosthesis, wherein the method mainly comprises the following steps:
preoperative scanning: performing preoperative contour scanning on a to-be-treated tooth of a patient by using a scanning device, so as to create a first digital model file; optical positioning and turning treatment: combining turning tool optical positioning with the first digital model file in a manner of tracking a medical apparatus by using an optical positioning system, turning the to-be-treated tooth into an abutment tooth, and creating a second digital model file from a turning process; physical model calculation: creating reversely, by using the second digital model file created previously from the turning process, an autologous crown model file of the patient from a process of turning the to-be-treated tooth into the abutment tooth; and fixed denture manufacturing: manufacturing, by using computer-aided design (CAD) and computer-aided manufacturing (CAM) and according to the second digital model file and the autologous crown model file, a fixed denture that meets needs of the patient.
