Abstract
One aspect of the present application provides a method for generating 3D digital model of teeth, the method comprises: scanning a patient's teeth with a first feeler gauge inserted in a first gap between two adjacent teeth, to obtain a first 3D digital model; extracting a position and a direction of the first feeler gauge from the first 3D digital model; and modifying the first gap of an original 3D digital model of teeth based on the specification, position and direction of the first feeler gauge, to obtain a refined 3D digital model of teeth.
