摘要： A method and system for producing a dental implant surgical guide is disclosed. A patient-specific virtual model is generated using image data specific to a patient and virtual dental implants. The virtual model aligns the image data with the virtual dental implants using modeling software. A virtual mold is generated from the virtual model, and a physical mold is generated from the virtual mold. The physical mold is covered with a thermoplastic sheet via a thermoforming process. Excess thermoplastic material is trimmed off after the thermoforming process to produce a thermoformed piece. Metal tubes corresponding to each the virtual dental implants are placed onto the physical mold denoting the position, trajectory, and depth of the one or more virtual dental implants. A dental implant surgical guide that contains the thermoformed piece with the one or more tubes is produced.

摘要： Embodiments of the invention provide systems and methods for generating combined image data representing a volumetric image of a subject and a color textured external surface of the subject. According to one embodiment, two-dimensional image data of a surface of the subject can be obtained from a two-dimensional imager. Volumetric data of the subject can be obtained from a volumetric scanner. The two-dimensional imager can have a known optical property and physical position relative to the volumetric scanner. External surface mesh data can be generated based on the volumetric data. The two-dimensional image data can be mapped to the external surface mesh data based on the known physical position of the two-dimensional imager and the volumetric scanner. Display image data including the two-dimensional image data mapped to the external surface map data combined with the volumetric data can be generated and displayed.
