Abstract
Objectives: This study aimed to determine the position of the incisors and its effects on the profile, identify any possible gender differences, and compare the maxillary and mandibular anterior teeth positions between participants of short, average, and long faces. Materials and Methods: This study comprised cephalometric radiographs of 82 participants (male: 42, female: 40) with a mean age of 21.9 +/- 2.8 years. The participants were divided into three groups: short face group: Frankfort mandibular plane angle (FMA) <25 degrees, average face group: FMA >= 25 degrees-<30 degrees, and long face group: FMA >= 30 degrees. Seven linear and eight angular measurements were measured and compared between the three groups. Results: No gender differences were found. The short face participants tend to have more proclined lower incisors, more protruded chin, more mandibular incisor display, and more retrusive upper lip position than the average and long face groups. Conclusions: The short face participants tend to have more proclined lower incisor, more protruded chin, a more mandibular incisor display, and more retrusive upper lip position than the average face and long face groups.
