A research project applying Solid Photography, an optical, three-dimensional technology, to automatic replication of dental crowns out of inexpensive, non-strategic material. This project investigated methods of obtaining complete surface measurement data, preparing this data for compatibility with machining requirements and replicating a dental crown. Measurements were made to an accuracy on the order of or - 0.002 inches on the exterior surfaces of a dental crown pattern and on the die upon which the crown pattern was formed. The data from the die exterior was used to form the crown interior. This project advanced the state of the art from feasibility to the initial stages of machining a closely fitting crown using a computer-controlled end mill following the measurement data obtained by Solid Photography.
