Abstract
The present invention provides a method of making and aligning digital images from oral tissues, dental implants, healing components, and dental restorations to design and manufacture dental implant retained restorations. Image data about the space available for the planned restoration, orientation of dental implants or abutments and aesthetic contour and occlusion of the prosthesis are all integrated into a virtual three-dimensional model of the prosthesis that can be sent to the clinician or laboratory to validate design intent and to manufacture the prosthesis. The virtual model is used by either a conventional rapid prototyping machine to produce a castable pattern or a number controlled mill to machine the restoration.
