Patent number: RE44465Abstract: A method, apparatus, and article of manufacture provide a system for electronically generating a color dental occlusion map within electronic model images. With the advances recently made computational systems, these computer based image systems may be used to permit end users to replace paper and physical models with electronic images. A mechanism to capture image representations of physical objects accurately and with sufficient resolution is provided in a form that is both inexpensive to operate while providing rapid turn-around for users. Second, a mechanism to visually display interaction between parts of an object is also provided. These features are expressly addressed for impressions of human teeth that are scanned to allow electronic images of the models of a patient's teeth to be represented and manipulated.Type: GrantFiled: April 5, 2012Date of Patent: August 27, 2013Assignee: GeoDigm CorporationInventors: Bruce Willard Hultgren, Timothy W.
