Problems solved by technology

[0003] At present, the technology of denture model molding is to obtain the condition of the teeth in the patient's mouth, analyze the condition of the teeth, obtain the denture model and process it into a denture. The traditional method of obtaining the condition of the teeth in the oral cavity does not pay attention to the distinction between adjacent teeth and cannot be accurately obtained. The accurate condition of a single tooth in the patient's mouth leads to insufficient accuracy of the generated denture model, and the denture generation process takes a long time, resulting in low denture generation efficiency

Abstract

The invention provides a false tooth model forming system and method based on cloud computing, and the system comprises an image obtaining module which is used for carrying out all-directional scanning on the oral cavity of a patient, and obtaining a three-dimensional digital image of the oral cavity of the patient, a model building module which is used for building a three-dimensional oral cavity model based on the three-dimensional digital image, and a false tooth generation module which is used for generating a false tooth for repairing according to the three-dimensional oral cavity model. By establishing the oral cavity internal model, the false tooth generation precision is improved, and by setting the false tooth generation method, the false tooth generation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of denture processing and molding, in particular to a denture model molding system and molding method based on cloud computing. Background technique [0002] Dentures are dentures that are inlaid to restore functions such as chewing, aesthetics, and pronunciation after tooth loss or extraction. [0003] At present, the technology of denture model molding is to obtain the condition of the teeth in the patient's mouth, analyze the condition of the teeth, obtain the denture model and process it into a denture. The traditional method of obtaining the condition of the teeth in the oral cavity does not pay attention to the distinction between adjacent teeth and cannot be accurately obtained. The accurate condition of a single tooth in the patient's mouth leads to insufficient accuracy of the generated denture model, and the denture generation process takes a long period, resulting in low denture generation efficie...
