Evaluation of soft tissue parameters for adults with accepted occlusion using Legan and Burstone analysis

Objective: The purpose of this study was to evaluate soft tissue parameters for adults, and applying a new method for soft tissue analysis to provide good diagnosis and treatment planning. Material and methods: Cephalometric radiograph of 100 adult subjects randomly selected with accepted facial proportions and normal occlusion aged 18-25 years. It s evaluated with Legan and Burstone analysis and compared with their study on white sample. Results: Egyptian population group were found to have more convex faces, protrusive lips and acute nasolabial angles. Males had more convex faces and protrusive lips than females. It can be concluded that the Egyptian populations group had significant deviations from the White standard soft tissue.
