Abstract

Background: To study the relationship between symphyseal morphology and antegonial notch depth in vertical, horizontal, and average growth pattern in patients with Class II Division 1 malocclusion. Materials and Methods: Pretreatment lateral cephalograms of 50 patients with angle’s Class II Division 1 malocclusion requiring orthodontic treatment were traced. The sample was divided into average, horizontal, and vertical growth pattern based on Jarabak’s ratio (Horizontal-16, Vertical-22, and Average-12). Symphysis depth, height, ratio (height/depth), and antegonial notch depth were evaluated and analyzed statistically. Results: In vertical growth pattern, symphysis ratio and symphysis height are correlated. In horizontal growth pattern, symphysis height is correlated to symphysis depth and symphysis ratio and antegonial notch depth is correlated with symphysis depth. In average growth pattern, symphysis height, and ratio are correlated with symphysis depth. Conclusion: Symphysis morphology and antegonial notch depth are highly correlated in horizontal growth pattern group.
