Introduction: Augmenting the malar area enhances the angularity and fullness of the mid face. Pop culture portrays people with high malar prominence and angular faces as beautiful and exotic. On the other hand, people with mid face deficiency tend to have a gaunt or hollow mid face leading to increased show of the sclera inferior to the pupil. Materials &
Methods: Thirty Class I and 30 Class III CBCT images (16 male, 14 female - each group) between the age group of 14-20 years were included in the study. Data collected from the patients reporting to the Insight CBCT Center, Pune. The CBCT images were analyzed with creation of hard and soft tissue slices for PPA and results were drawn with statistical analysis. Results: The Class I male horizontal slices had smaller measurements (P<0.05) in both the soft and hard tissue than Class III by 0.4 mm to 1.5 mm at nearly nine measurements of PPA. The Class III sample pattern profile measurements were larger by 0.6 mm to 1.7 mm. The laterality measurements also found to be larger for the Class III as compared to Class I. Discussion &
Conclusion: Class III males found to have a larger mid face deficiency than Class I male. Anterior component of the Class III male’s mid face showed posterior positioning. Class I and Class III female sample showed similar size and position of the mid facial complex (statistically insignificant). Class III male’s mid facial deficiency was more, mid face complex positioned further laterally and elongated more anteriorly as compared to the Class I male and female Class III.
