RELATIONSHIP OF ANTERIOR AND POSTERIOR OCCLUSAL PLANES WITH DIFFERENT SAGITTAL AND VERTICAL PATTERNS IN ADULTS

Introduction: The Occlusal plane plays an important role during orthodontic treatment. occlusal affects the position of mandible, smile esthetics, masticatory function, and stability post-orthodontic.Objectives: To evaluate relationship anterior (AOP) posterior (POP) with skeletal vertical patterns.Materials Methods: Lateral cephalometric radiographs 180 adult patients different classes malocclusion were used. Several angular measurements measured compared among all study groups to existence a between AOP POP patterns.Results: patterns showed significant difference in angle relative both SN FH planes (p-value =0.000**) having steeper inclined Class II flat III. While no was found (p=0.217) malocclusion. (P=0.000**) three pattern showing steep incline high group. Conclusions: have impact on jaw base where variation its angulation had affected sagittal facial patterns. III, while same value Classes
