3D DATA GENERATION FOR PROSTHETIC CROWN PREPARATION OF TOOTH

摘要

A method for generating a preparation surface of a tooth of a subject comprises: a. receiving surface data of the tooth of the subject; b. determining one or more parameters of the tooth of the subject by analyzing the surface data; and c. generating the preparation surface using the one or more parameters; d. wherein the preparation surface of the tooth comprises a three-dimensional model of the surface of the tooth, an intended cut region, or both. The surface data comprise two-dimensional X-ray images of the tooth taken along at least two planes that are not parallel and/or two-dimensional Computed Tomography (CT) images of the tooth. The method comprises determining an extent of tooth decay by analyzing the surface data. The method comprises generating one or more missing surface patches to replace an incomplete or missing scanned surfaces of the tooth. Missing surface patches are generated by a machine learning algorithm and/or a neural network.
