Design method, system and device of prosthodontic body and readable storage medium

Abstract

The invention discloses a design method, system and device of a prosthodontic body and a readable storage medium. The method comprises the steps of obtaining three-dimensional scan data of the oral cavity of a patient; on the basis of comparing the similarity of the three-dimensional scan data and three-dimensional oral data in an oral model database, selecting the closest three-dimensional oral data for the three-dimensional scan data from the established oral model database; on the basis of a tooth area of ill teeth in the oral cavity of the patient, selecting teeth on the corresponding tooth area in a three-dimensional oral model corresponding to the closest three-dimensional oral data as the prosthodontic body, and obtaining three-dimensional data of the prosthodontic body; convertingthe three-dimensional data of the prosthodontic body into processing data required by dental digital processing equipment. The system comprises a receiving unit, a comparison unit, a screening unit and an output unit. According to the design method, system and device of the prosthodontic body and the readable storage medium, the tooth design is completed on the basis of a computer without manual operation, and the time and effort are saved; meanwhile, the errors caused when different levels of operators operate the system to design prosthodontic bodies can be avoided, and the comfort degree ofthe patient wearing the prosthodontic body is improved.

Description

technical field [0001] The present disclosure generally relates to the field of dental digital design, and in particular relates to a design method, system, device and readable storage medium of an oral prosthesis. Background technique [0002] Since everyone's teeth are shaped differently, every dental case in medicine requires a specially designed restoration. [0003] Traditionally, the lost-wax method is used to make the shape of dental restorations. In this method, after the doctor grinds away the patient's lesioned teeth, he uses the impression material in the patient's mouth to take out the patient's oral model, and then transforms it through the plaster negative mold and positive mold. , to make a plaster model exactly like the patient's mouth. Then, a lost-wax method is used to make a wax model or plastic model of the shape of the restoration on the plaster model (obtained by melting wax or plastic, solidifying drop by drop, and then grinding and polishing), and th...

Problems solved by technology

[0006] However, there is a problem in the current CAD / CAM (Computer-Aided Design / Computer-Aided Manufacturing) system: after the doctor builds the 3D model of the patient's oral cavity on the computer, the restoration design is done manually, that is, the 3D graphics processing software is manually operated. Adjust various three-dimensional parameters of the restoration to be designed, such as: size, axial direction, jaw curve, arch curvature, occlusion, minimum thickness, connecting body strength, etc.), so that the final designed restoration is sufficient for the patient

However, this process requires a lot of experience in dental design, and operators need to undergo a lot of technical training before they can work. At present, CAD / CAM systems are lacking in the intelligent design of restorations.
