Abstract
A method for displaying a superimposition of a second dental model on a first dental model of a patient's dentition, obtains a first 3D model of the patient's dentition and a segmentation of the first 3D model. A second 3D model of the patient's dentition and a segmentation of the second 3D model are obtained. A selected tooth is identified from the segmented teeth of the first and second 3D models. A post-treatment target position for the selected tooth of the first 3D model is determined according to a movement indication calculated for the selected tooth. The second 3D model is registered to the first 3D model based on the target position of the at least one selected tooth. An imposition of the second 3D model onto the first 3D model of the patient dentition is displayed.
