Abstract

Computer system (100) and computer-implemented method are provided for automated generation of manufacturing-machine control data (291) for the manufacturing of an orthodontic appliance (280) for a patient (2). Based on three-dimensional representations (210) of the patient's oral anatomy and an appliance type (211) of the orthodontic appliance, the system generates a control structure (111) comprising a mesh providing an initial representation (111pi) of an aimed appliance geometry, and subdivision manifold-related shape attribute information (Ills) with a subdivision scheme, implicit manifold-related shape attribute information (111i) with a scalar field, and information for evaluating a respective position of the respective vertex. Executing a subdivision according to the subdivision scheme generates a modified control structure (111m). For added vertices, respective shape attribute information is evaluated to obtain the position of the respective vertices. Once a final mesh is obtained, it is transformed into manufacturing-machine control data for the manufacturing of the orthodontic appliance, and provided to corresponding manufacturing means (290).
