A feasibility study applying Solid Photography, an optical, three-dimensional technology, to automatic replication of dental crowns out of inexpensive, non-strategic material. This study demonstrated that the interior and exterior surfaces of a dental crown pattern can be measured by Solid Photography to an accuracy on the order of or - 0.002 inch. The interior surface was obtained by measuring the tooth post upon which the crown pattern was formed. A numerically-controlled end milling machine carved a replica of the crown in stainless steel based on the measured data.
