Abstract
Introduction: The horizontal position of upper and lower lips has been of great concern when planning a treatment plan of an orthodontic patient, because the purpose of orthodontic treatment is to establish both an aesthetic facial profile and a functional occlusion. Objectives: To determine differences in anteroposterior lip position in different skeletal malocclusions in district Solan population and to compare these values with those of Sudanese population. Materials and Method: Pre-treatment lateral cephalogram of 114 subjects were taken in natural head position. The subjects were then divided into 3 groups on the basis of ANB angle. 5 reference lines (Steiner, Burstone, Sushner, Holdway, and Ricketts) were traced and their linear distance w.r.t upper and lower lips were measured for all the 3 groups. Then the results were compared to the distance of upper and lower lips from S1, B and E line in the Sudanese population in the 3 different skeletal malocclusion groups. Results: Skeletal class II was found to have the more protrusive lips and differed significantly from Class III. The distance of these lines showed variance in the Solan population and Sudanese population. Conclusion: The sagittal lip position was associated with the pattern of skeletal occlusion.
