Abstract

In the present study, mandibular morphology was investigated on lateral cephalometric head films and dental casts of 60 subjects (30 females and 30 males) who had different vertical facial growth patterns. The sample had a mean age of l3 .5 years, with a range of ll to 15.5 years. The subjects were divided into three groups with regard to vertical facial growth by using the SN/GoGn angle to define low-angle, normal, and high-angle groups. In addition, each group was divided into two subgroups according to sex. The effects of the SN/GoGn angle and gender on mandibular morphology were investigated by means of analysis of variances. Tan Go, IMPA, SL, and EL measurements were found to be related to SN/GoGn, and the measurements of Go-Gn, Symphysis depth, and Intermolar width to be related to sex.
