Based on the patient's 3D scan data, using AI technology, the crown prosthesis design that is most suitable for the patient's oral environment is generated in seconds. At the same time, it automatically identifies the margin line between the tooth and gum of the crown prosthesis to be manufactured and suggests an optimized margin line. Then, it goes through a process of creating an optimal crown design in a matter of seconds, considering the surrounding and antagonist teeth. Finally, the crown design may be downloaded in the desired file format (STL, OBJ, PLY, etc.) and sent to a 3D printer or milling machine for an immediate prosthesis production.
