Abstract

Disclosed is a computer-implemented method for automatically designing a dental restoration for placing in a dentition of a patient, the method comprising the steps of: obtaining digital three-dimensional (3D) surface data representing a surface of the dentition of the patient in 3D space, wherein the surface comprises a preparation surface configured to receive the dental restoration; pre-processing the 3D surface data to generate a discretized 3D model comprising granularity elements defining a discretized representation of at least a part of the 3D surface data, wherein the at least a part of the 3D surface data comprises the preparation surface; pre-processing the discretized 3D model to generate an encoded representation of the discretized 3D model, wherein the encoded representation comprises the granularity elements, and each granularity element is encoded with at least distance information from the point to at least one functional surface; processing the encoded representation by using a trained model configured to process the encoded representation; receiving an output of the processing from the trained model, wherein the output comprises at least a part of the dental restoration; and automatically designing the dental restoration based on the received output.
