Abstract: A system and method for evaluating dental treatment utilizes virtual models created from scanned plaster casts. Patient's teeth are directly scanned with a three dimensional scanner or plaster casts of the patient teeth following treatment are scanned for evaluation. A planned configuration based on a plaster cast prior to treatment is created and the desired position and the two models are compared so that the actual position of the teeth may be compared to the desired position after treatment. Superimposition of the virtual models provides accurate and precise measurement of variances between the two virtual models. Difficulties due to superimposing the models, which are of the entire arch and evaluations based on individual teeth are overcome by applying an iterative closest point algorithm to correct the position and provide a truer measurement for evaluation.

Abstract: 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.
