Abstract: Techniques are described for automating the design and manufacture a dental restoration appliance for restoring the dental anatomy of a patient. For example, a system processes a digital three-dimensional (3D) model of a future (desired) dental anatomy of a patient, the future dental anatomy representing an intended shape of at least one tooth of the patient. The system includes a landmark identifier configured to automatically compute, based on the digital 3D model of the future dental anatomy of the patient, one or more landmarks of the future dental anatomy of the patient. The system also includes a custom feature generator configured to automatically generate, based on the one or more landmarks, one or more custom appliance features for a dental appliance for restoring the at least one tooth of the patient. The system further includes a memory device configured to store a digital model of the dental appliance.

Abstract: At least some aspects of the present disclosure direct to an injection mold used for manufacturing an apparatus. The injection mold includes a shell comprising a plurality of layers additively formed using a shell material, a cavity formed by the shell, and a heater disposed in the cavity. In some cases, the shell material includes a polymer material. The cavity is filled with a filler material. The shell comprises a parting surface, where the parting surface has a molding structure in conformation with a surface of the apparatus.

Abstract: At least some aspects of the present disclosure direct to a mold insert used in an injection mold having a receiving surface. The mold insert comprises a plurality of layers additively formed by an insert material to comprise a molding surface, an insert body, and an insert surface in conformation with at least a portion of the receiving surface. The molding surface is a surface of the insert body and the insert surface is a surface of the insert body. The molding surface and the insert body comprise a molding structure in conformation with a surface of an apparatus to be made using the injection mold.
