Abstract

A system for generating missing data for 3D models of intraoral structures of a patient. The system may include a hand-held intraoral scanner and a computer having instructions that the system to scan the intraoral structure of a patient to generate first 3D data of the surface of a prepared tooth, generate a 3D virtual model of the prepared tooth based on the first 3D data, determine the 3D virtual model is missing a surface associated with the prepared, generate second 3D data approximating the surface that is determined to be missing from the 3D virtual model intraoral structure that is missing, and combine the second 3D data with the 3D virtual model such that the 3D virtual model includes the approximated surface, wherein the approximated surface approximates the prepared tooth associated with the surface determined to be missing from the 3D virtual model.
