A digital model intelligent design method for dental digital impression apparatus

Abstract

The invention belongs to the technical field of medical computer-aided design, and specifically discloses an intelligent design method for a digital model of an oral cavity digital impression apparatus. The method includes data collection, data preprocessing, intelligent design, candidate tooth crown matching, Steps such as shape adjustment, by intelligently matching and adjusting the candidate crown model after extracting the distance between the adjacent teeth, the buccal and lingual arch convex arcs, the height of the gingiva, and the morphological characteristics of the cusp and groove of the opposing tooth, The purpose is to quickly and accurately produce the teeth to be produced, which speeds up the processing speed of the denture and reduces the intermediate links of processing.

Description

technical field [0001] The invention relates to the technical field of medical computer-aided design, in particular to an intelligent design method of a digital model for a dental digital impression instrument. Background technique [0002] Traditionally, when making dental implants or dental restorations in the oral cavity, the dentist usually uses an oral scanner to scan the patient's oral cavity, obtain the 3D model data of the teeth in the oral cavity, and then transmit it to a professional design factory for design. Processing, professional design factories also need to design manually according to the design requirements put forward by dentists, combined with their own design experience; however, this traditional semi-manual design method is time-consuming, low in efficiency, long in production cycle, and The designers in the factory did not have direct contact with the patients, so it was difficult to adjust the standard teeth to the optimal size and shape. As a resul...

After the installation, the dentist needs to make subsequent adjustments
