Denture tooth selection: an analysis of the natural maxillary central incisor compared to the length and width of the face. Part I.

A project was devised by the removable prosthodontic faculty to determine clinically if there is a correlation between the length and width of the maxillary central incisor on a cast and the length and width of the face. A millimeter gauge was used to measure the lengths and widths of the maxillary incisor on a cast. The Trubyte tooth indicator was selected to measure the length and width of the face. This tooth indicator is designed for calibration of the 16 to 1 ratio between facial dimension and maxillary central incisors.
