Intelligent design method of digital model for oral digital impression instrument

Abstract

The invention belongs to the technical field of medical computer-aided designs and particularly discloses an intelligent design method of a digital model for an oral digital impression instrument. Themethod comprises the steps of data acquisition, data preprocessing, intelligent design, alternative dental crown matching, dental pattern adjustment and the like. A to-be-produced tooth is rapidly and accurately produced through extracting a distance between adjacent teeth of the to-be-produced tooth, buccal and lingual dental arch crown curves, a gum diameter height and cusp pit and fissure ridge shape features of opposite jaws, performing intelligent matching and adjusting alternative dental crown models, so that the processing speed of a false tooth is increased and an intermediate link ofprocessing is reduced.

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
