Abstract
A process for aligning at least two different digital scan data each representing at least a part of a dentition of a patient includes scanning the patient's dentition so as to record volumetric 3-dimensional digital scan data in a volumetric coordinate system and scanning the patient's dentition so as to record topographic 3-dimensional digital scan data in a topographic coordinate system. The teeth or jaws of the patient's dentition are segmented and approximated from the digital scan data by grouping the digital scan data with respect to structures and approximating a surface of the segmented teeth using triangle meshes. A key point determination is performed for each tooth based on the triangle mesh representation to define 3-dimensional coordinates of a tooth surface feature in the volumetric or topographic coordinate system. The key points are aligned to obtain aligned digital scan data by coordinate transformation of one coordinate system.
