    摘要: A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.

    摘要: An imaging system is described. In one aspect, a method includes accessing pressure sensor data from a pressure sensor being bitten by a patient, accessing occlusal pattern data corresponding to the patient, correlating the pressure sensor data with the occlusal pattern data, and identifying a location of the pressure sensor relative to the teeth of the patient based on the correlated pressure sensor data with the occlusal pattern data.

    摘要: A computer-implemented method and system of determining a material surface from a volumetric density file includes generating a density frequency distribution of a volumetric density file of a dental impression and determining an iso-value of density between air and a particular material in the density frequency distribution. A computer-implemented method and system of creating a digital model from a CT scan of a physical dental impression includes selecting an iso-value of density for a digital volumetric density file having one or more voxels, generating one or more digital surface points in virtual 3D space for each of one or more voxels, and selecting a subset of digital surface points from the one or more digital surface points. A computer-implemented method and system of optimizing a digital surface includes moving one or more digital surface points to satisfy a criteria of optimum digital surface selection.
