Abstract
Introduction: The horizontal position of upper and lower lips have been of great concern when planning a treatment plan of an orthodontic patient, because the purpose of orthodontic treatment is to establish an esthetic facial profile and not just a functional occlusion.
Objectives: The objective of this research was to determine anteroposterior lip position in three skeletal malocclusion groups and to analyze different soft tissue lines.
Material and Methodology: This study comprised of eighty one subjects and lateral cephalographs were taken in natural head position. Five reference lines—Sushner, Steiner, Burstone, Holdway, and Ricketts were drawn after radiographs were traced. The linear measurement between the lips and the five reference lines was recorded. For statistical analysis, SPSS 21 was used.
Results: Using five soft tissue reference lines, a significant difference between the anteroposterior position of the lips in various skeletal malocclusions was discovered.
Conclusion: The skeletal malocclusion pattern was shown to be related to the sagittal lip positions. For sagittal lip position analysis, Every group of skeletal malocclusions had a different preferred reference lines.
