  • The purpose of this research study is to determine the range of mesiodistal width discrepancies for a single missing maxillary incisor, in which digital restoration of the missing tooth produces: (1) no perceivable discrepancy, or (2) a result that would be considered unacceptable by patients and dental professionals respectively. An electronic survey was administered in which participants were asked to look at a series of carefully modified digital models of a maxillary arch, and then assess differences in width of two teeth and rate the overall appearance of the teeth. Results indicate a range of actual mesiodistal width discrepancy for a central incisor (-1.5mm to +1.0mm) and lateral incisor (-1.0mm to +0.5mm) for which a digital wax-up was considered esthetically acceptable by at least 95% of patients.
