Cephalometric analysis of dentofacial normals.

A comprehensive cephalometric analysis of "normal" adults was accomplished by examining a carefully selected subject group. Fifty-six adult Caucasians with Class I skeletal and dental relationships and good vertical facial proportions were analyzed morphologically with a computerized craniofacial model. By the incorporation of a large number of soft-tissue measurements, facial profile and proportionality were analyzed and compared with methods that are presently used to evaluate facial esthetics. The data provide relevant measurements that are useful in the diagnosis and treatment of adults with dentofacial deformities. Horizontal soft-tissue chin prominence was nearly equal for males and females relative to subnasale, soft-tissue nasion, and glabella.
