Abstract

A method of capturing data from a patient's dentition with the steps of positioning a first optical sensor relative to patient's dentition, capturing the shape of a tooth in the patient's dentition, independent from capturing the shape, measuring a color at a location on the tooth, and providing a correlation between the location of the color and a coordinate in the captured shape. The invention helps providing a dental restoration at a relatively high optical, mechanical, and geometric quality.
