Abstract
Abstract An anterior tooth characterization guide includes several sets of anterior tooth samples which each have differing characteristics. The characterization guide is useful in connection with a method for selecting characterizations for an anterior tooth prosthesis and a process for fabricating a characterized tooth prosthesis, which permit a dentist to relay to a laboratory an accurate representation of the tooth prosthesis to be manufactured. In this regard, the characterization guide is utilized to select a dentin color for the tooth prosthesis from several tooth samples in which the incisal color is constant. The body to incisal relation for the tooth prosthesis may also be selected from tooth samples in which the dentin is constant, and the amount of white stain for the tooth prosthesis may be selected from the tooth samples in which the dentin and enamel are constant. Similarly, the tooth samples of the characterization guide are utilized to select the incisal color, the dentin structure and translucent effect, and additional characterization features including cracking, spotting and hallow. In connection with the process for fabricating a characterized tooth prosthesis, a dentin-like base of a selected color is formed over a stone mold, and one or more appliques included selected tooth characterizations are placed on an exterior surface of the base. An enamel laminate is applied over the appliques, and the base, appliques and enamel laminate are fused together.
