Abstract

Objective: The purpose of this study was to assess the mandibular symphysis morphology and its dimensions in different anteroposterior skeletal relationships, Class-I / Class-II/ Class III, in patients presented to orthodontics department of Rehman College of dentistry.

Materials and Methods: A total of 50 lateral cephalograms of patients (age > 18 years, mean age 22 years) irrespective of gender were randomly selected from patient’s records of the department. Measurements were taken on software IC Measure version 1.3. All the radiographs were imported into the software and analyzed. The image was digitized on six points for linear and angular measurements. The main outcome measure was the “mandibular symphysis morphology and its dimensions in anteroposterior plane” in all skeletal malocclusion classes.

Results: The relationship between the variables was assessed by one way ANOVA test. A larger angle of concavity of the chin, and larger MS dimensions and area (P <0.05) were found with a Class III skeletal relationship compared to Class I and Class II relationships. Males had a decreased angle of concavity than females. There were, however, no significant differences in the vertical dimension of MS and angle of convexity between the three groups.

Conclusion: Class III skeletal jaw relationship exhibits a decreased concavity of anterior contour of MS as compared to the other groups. Larger dimensions and area of MS are found in Class III than in class I and class II part of MS. It is clear from the results that the alveolar part of MS compensated for the skeletal relationship in the Class III pattern.
