Evaluation of Maxillary Anterior Teeth Width and Their Relation to the Calculated Values for Smile Designing

Abstract

The present study was conducted to determine the golden proportion, golden mean, and the Preston proportion of the individuals between the widths of six maxillary anterior teeth and to determine which proportional formula exists in the population. This study was conducted among 60 participants between 18 years and 30 years of age with an esthetic smile. They were grouped into 30 females and 30 males. Maxillary arch impressions were made using irreversible hydrocolloid material from each individual. The width of the anterior teeth on the graph paper was analyzed by using digital vernier caliper. The data were statistically analyzed by one way ANOVA test. The study revealed that the formula of golden proportion and golden mean had no statistical differences between males and females but the Preston proportion has shown statistical differences in the total population. From the current study, it was concluded that the formulas of golden mean and golden proportion proposed by Ward can be used for smile designing and full mouth rehabilitations. Demand for smiles has gained its importance with time. The golden proportion, golden mean, and the Preston proportion are the guidelines used by the professional for better esthetic proportion in the dentition.
