An Evaluation of the Integumental Facial Profile and It's Relation to Underlying Structures

Abstract

Aims : To evaluate the correlations between the skeletal measurements and soft tissue measurements in males and females. Materials and Methods: Eighty students (40 males and 40 females) were selected aged (12-14) years with class I normal occlusion from intermediate schools in Mosul City. A standardized lateral cephalometric radiograph was taken for each student, eighteen variables, 9 angular (6 skeletal and 3 soft tissue) and 9 linear (3 skeletal and 6 soft tissue) were used in this study. Results: In males, angle of facial convexity positively correlated with angle of skeletal convexity and negatively with the angle describes the relationship of the maxillary and mandibular bases in the sagittal planes.The length of mandibular corpus was positively correlated with upper lip thickness, lower lip thickness at labral inferius and upper lip height. Upper lip thickness at labral superius was positively correlated with angle defines the anteroposterior position of maxilla in relation to anterior cranial base and angle indicates the anteroposterior position of the mandible in relation to the anterior cranial base.Lower lip height was positively correlated with the mandibular plane angle .In females, angle of facial convexity was positively correlated with angle of skeletal convexity and negatively with the angle describes the relationship of the maxillary and mandibular bases in the sagittal planes. The angle measures the protrusion of upper lip relative to the inferior border of the nose was negatively correlated with angle of skeletal convexity and mandibular length and positively with angle describes the relationship of the maxillary and mandibular bases in the sagittal planes.Angle of skeletal convexity was positively correlated with upper lip thickness at point A and upper lip thickness at labral superius. The mandibular plane angle was positively correlated with lower lip height. The angle describes the relationship of the maxillary and mandibular bases in the sagittal planes was positively correlated with labiomental angle and negatively with upper lip thickness at labral superius. The mandibular length was negatively correlated with labiomental angle and positively with upper lip thickness at point A ,
