Abstract

A method of making a dental restoration has the steps of capturing an image of a tooth, posterizing the image, determining a tooth color structure, providing information about a multicolored block having a block color structure, matching the tooth color structure and the block color structure, based on the matching, determining a position within the block in which the tooth color structure and the block color structure match, and machining the dental restoration from the block at the determined position. The invention helps facilitating the making of dental restorations at maximized aesthetics.
