A method to combine dental anatomy data includes, by the use of a computing device: receiving volumetric dental data and superficial dental data; segmenting the crowns of the volumetric dental data from the roots of the volumetric dental data; segmenting the crowns of the superficial dental data from the gingiva of the superficial dental data; transforming superficial dental data of the crowns to substantially align with volumetric dental data of the crowns; stitching the transformed superficial dental data of the crowns to volumetric dental data of the crowns; and outputting for display an image data based on the combined dental data.
