Abstract

Background/Purpose
The analysis of the lips position is one of the most important soft tissue analyses indicating the stability of the front teeth position and facial aesthetics. The aim of this study is to establish the values of the soft tissue lip angles of a facial profile in subjects with the dentoskeletal pattern of Class I taken as a control group in relation to Class II division 1, Class II division 2, and Class III.
Materials and Methods
This study included the examination and the analysis of cephalometric radiography derived lateral cephalogram evaluating the profile angles of 120 adult Caucasian orthodontic patients (60 females and 60 males) from the central Balkan area. Generally, the subjects with Class I had harmonic profiles due to the orthognatic jaw relationships; this group was taken as a control one and compared to the other three groups: Class II division 1, Class II division 2 and Class III. The following angles were examined: the projection of the upper lip to face (Ls-N- Pg) the angle of the upper lip (Ls- Sn-Pg), the projection of the lower lip (Li-N-Pg) and the interlabial angle (Sn- Ls/Li-Sm).
