Abstract

The purpose of this study was to evaluate the interrelationship of the soft and hard tissue changes after both maxillary and mandibular anterior segmental surgery in bimaxillary protrusion patients. 11 patients had received both maxillary and mandibular anterior segmental surgery and were investigated radiologically with lateral cephalogram. The results were as follows : 1. The correlation of maxillary hard and soft tissue horizontal changes were relative high. : Coefficient between UIE and Stms was 0.89 (p<0.001). 2. The correlation of mandibular hard and soft tissue horizontal changes were very high, especially at the chin. : Coefficients were over 0.90 (p<0.001) 3. All points were moved superiorly except SLS, LS, Stms. 4. Upper and lower lip convexity to the E-Line were decreased (p<0.001) and postsurgical facial profiles were changed very esthetically.
