Abstract
A method of milling and polishing a set of tooth mold parts by milling a first and second tooth mold parts of a set of mold parts using a first and second tool path program, then polishing the mold parts using the first and second tool path program, to form polished mold parts adapted to form an enamel layer of a prosthetic tooth. A method is provided of molding artificial teeth each having a molded enamel layer and high definition labial striations, by milling and then polishing a set of at least three tooth mold parts in mold making material. The milling and polishing is directed by three milling programs which use data, representative of the surface of one of the tooth mold parts. The data is adapted by the milling program to direct the milling and polishing. The milling of each of the parts includes executing a first pass with a first mill and executing a second pass with a second mill. The first mill has a first mill end. The second mill has a second mill end, which is smaller in size than the first mill end. High definition artificial teeth having labial striations are repeatedly manufactured in the set of polished mold parts.
