Comparison of three anthropometric techniques for tooth selection

The absence of a reliable method to assess the proper dimension of artificial teeth can lead to errors that reduce aesthetic outcomes of the dental treatment. Previous studies indicate facial anthropometric parameters as guides to estimate the width of the six maxillary anterior teeth. Nasal width, distance between the medialis angles of the eyes and mouth width were measured in young subjects Brazilian as well as the width of their six maxillary anterior teeth. Data were analyzed by ANOVA/Tukey's (p < or = 0.05). The distance between the medialis angles of the eyes is a reliable anthropometric method to indicate the width of artificial teeth similar to the natural extracted.
