Abstract

A shade matching method for a tooth obtains a plurality of digitized tooth shade references, obtains a three-dimensional (3D) surface representation of a tooth and associated color information defined on the three-dimensional (3D) surface, selects a region on the three-dimensional (3D) surface representation of the tooth, determines a plurality of correspondences with the common tooth shape of all the tooth shade references, computes color difference with each of the tooth shade reference from the plurality of tooth shade references, and records the label corresponding to the shade reference with a smallest difference.
