Abstract
A method and system for generating a color-textured three-dimensional dental model is specific to a patient is disclosed. According to one embodiment, a three-dimensional dental model that is deficient of volumetric data for a three-dimensional anatomical landmark is obtained. A two-dimensional anatomical landmark of a two-dimensional intra-oral photograph that corresponds to the three-dimensional anatomical landmark of the three-dimensional dental model is identified. The two-dimensional intra-oral photograph is projected onto the three-dimensional dental model. The three-dimensional anatomical landmark is calculated from the projection of the two-dimensional anatomical landmark of the two-dimensional intra-oral photograph.
