ABSTRACT:
A prosthetic tooth having an enamel layer which has a zone of substantially constant thickness. This tooth is molded using a dental tooth mold part prepared by imaging a dental pattern of a prosthetic tooth shade layer and/or shader mold part outer surface, and forming the dental pattern in a mold by program directed milling. A family of prosthetic teeth is provided including a first tooth in a first set of teeth having a first overall labial length, and a first back length, and a second tooth in a second set of teeth having a second overall labial length, and a second back length. The invention provides a prosthetic incisor tooth including a tooth body having two generally symmetrical curved grooves between three curved ridges on the labial face of the body at the incisal end of the body. The grooves are deepest at the incisal end and extend substantially from the incisal edge to at least about 15 percent of the overall tooth length.
