Soft Tissue Profile of Cervicomental Region in Subjects with Normal Occlusion

Abstract

In orthodontic treatment, not only improved functional malocclusion but also esthetic facial balance is important. In addition to the morphology of the anterior facial region, that of the cervicomental region seems to be an important factor in the patients with jaw deformity when the craniofacial region as a whole is taken into consideration.
The purpose of this study was to establish standard values for determining the soft tissue profile of the cervicomental region in selected Japanese adults with normal occlusion by means of cephalometric analysis of the lateral cephalogram.
Results:
1. There was no significant difference in both lip-chin-throat and cervicomental angles between the male and the female subjects with normal occlusion. The lip-chin-throat angle was 113.2 ± 6.76°, and the cervicomental angle was 116.6 ± 9.94°.
2. The mean value of throat length was 35.2 ± 3.68mm. It was 36.57 ± 3.60mm in the male and 33.36 ± 3.01mm in the female. The male-female difference was significant only for throat length. This study established standard values for the cervicomental region in the Japanese adults with normal occlusion. This is considered to be one of the items that should be examined in case of genioplasty in the future.
