1. A computer-implemented method comprising: receiving a three-dimensional dental model including three-dimensional volumetric data specific to a patient; receiving a plurality of two-dimensional intra-oral photographs specific to the patient; identifying a plurality of three-dimensional anatomical landmarks of the three-dimensional volumetric data; identifying a plurality of two-dimensional anatomical landmarks of the plurality of two-dimensional intra-oral photographs that correspond to the plurality of three-dimensional anatomical landmarks; projecting the plurality of two-dimensional intra-oral photographs onto the three-dimensional dental model based on the plurality of two-dimensional anatomical landmarks that correspond to the plurality of three-dimensional anatomical landmarks; and generating a patient-specific three-dimensional dental model including the three-dimensional volumetric data and the plurality of two-dimensional intra-oral photographs.
