    Abstract: A computer-based prosthodontic method is provided, for enabling a dental practitioner to define a finish line of a dental prosthesis of at least one tooth to be fitted over a tooth preparation. The method comprises the following steps: providing a three-dimensional (3D) digital data relating to the patient's dentition, the 3D data includes data representative of the surface topology of the preparation and its surroundings; generating first finish line data representative of at least a portion of the finish line and superimposing an image of the finish line on an image of the dentition; obtaining second finish line data determined on the basis of input received from a dental practitioner; and using the second finish line data to update the first finish line data and superimposing the updated data on the dentition image.

    Abstract: A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.

    Abstract: Embodiments relate to adding customized cut line information to a shell that is to be formed over mold of a dental arch. In one embodiment, a processing device generates or receives a digital three-dimensional model of a mold for a dental arch of a patient. The processing device determines a cut line for a shell that is to be formed over the mold for the dental arch of the patient. The processing device then supplements the digital three-dimensional model by adding an auxiliary structure to the digital three-dimensional model, wherein the auxiliary structure comprises at least one of an elevation or a depression that extends along the cut line in the digital three-dimensional model, wherein the auxiliary structure will cause the shell formed over the mold to have an impression of the auxiliary structure that identifies the cut line.
