[A cephalometric comparison of skeletal profile and soft tissue profile on adults with normal occlusion].

This study is realized to correlate skeletal and soft tissue profiles cephalometrically on (45 males - age 20 and 20 females-average chronological age 18.2 +/- 0.58) total 65 adults with normal occlusion. For skeletal analysis GoGnSN, SNA, SNB, ANB angles and convexite and face angles which are accepted as the certain commune characteristics of profile are measured as well. Lower and upper lip positions were determined according to Steiner's "S plane" on individuals with normal dental occlusion and skeletal pattern. Having drawn soft profile and perpendicular to face plane (Na-Pg) from the tips of lips, chin and nose, thicknesses of soft tissue are measured. The mean values obtained, standard deviations and correlation coefficients were evaluated by using Systat package program. Relationships between the convexite angles and soft tissue thickness are found significant on males and lip positions and soft tissue relationships on both sexes are found meaningful.
