    摘要： A method of producing a crown for a custom implant abutment is carried out as follows. The method begins by preparing a patient's existing dental structures, viz., positioning a dental implant in the patient's mouth. Using a scanner device and associated modeling software, a first 3D model is obtained of a sufficiently large portion of an implant abutment to be attached to the implant. This scan is performed extra-orally. Preferably, the sufficiently large portion is that portion of the abutment bounded by a margin curve. After the implant abutment is attached to the implant (intra-orally), the scanner is used to obtain a second 3D model of the implant abutment attached to the implant (i.e., an intra-oral scan). Using the modeling software, the first 3D model is then aligned to the second 3D model. Thereafter, a boundary curve on the first 3D model is identified. Using the boundary curve to trim the first 3D model, the system then produces a third 3D model. Using the boundary curve, the third 3D model and the second 3D model, the system then creates a fourth 3D model, which is a model of a virtual dental item. Using a computer-assisted milling machine, the model of the virtual dental item is then used to produce an actual crown, which is then attached to the implant to complete the process.

    摘要： A method to visualize and correct alignment errors between paired 2D and 3D data sets is described. In a representative embodiment, a display interface used for dental implant planning includes one or more display areas that enable the operator to visualize alignment errors between the paired 2D and 3D data sets. A first display area renders 3D cone beam data. A second display area renders one or more (and preferably three (3) mutually orthogonal views) slices of the cone beam data. A third display area displays a view of a 2D scanned surface map (obtained from an intra-oral scan, or the scan of a model). According to a first aspect, the view of the 2D scanned surface map in the third display area is “textured” by coloring the 2D surface model based on the intensity of each 3D pixel (or “voxel”) that it intersects.

    摘要： A structured light pattern digitizing method is combined with photogrammetry to determine a 3D model of an object. The structured light digitizing operation generates a 3D model of the object being scanned, and this model is then used to compute a higher accuracy model using photogrammetry.
