  • Publication number: 20230113425
    Abstract: The disclosure relates to the technical field of medical computer-aided designs, and particularly relates to an oral digital impression instrument that includes a set of computer-readable instructions configured to implement an intelligent design method of a digital model. The method includes 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 teeth adjacent to the to-be-produced tooth, buccal and lingual dental arch crown curves, an occlusal gum diameter height and cusp pit and fissure ridge shape features of opposite jaws, and performing intelligent matching and adjusting alternative dental crown models, so that the denture processing speed is increased and intermediate links in the processing are reduced.
