ABSTRACT

Aim: To evaluate the correlation between the symphyseal angle and vertical skeletal parameters in skeletal Class I malocclusion. Materials and Methods: Forty-five subjects with skeletal Class I malocclusion were divided into horizontal, average, and vertical growth pattern groups. Lateral cephalograms were analyzed to measure the symphyseal angle, SN–GoGn angle, and Jarabak ratio. Statistical analysis was performed using ANOVA and Pearson's correlation test. Results: The symphyseal angle was highest in horizontal growers and lowest in vertical growers. It showed a strong positive correlation with the Jarabak ratio (r = 0.741) and a strong negative correlation with the SN–GoGn angle (r = −0.812) (p < 0.001). Conclusion: The symphyseal angle is significantly associated with vertical skeletal parameters and may serve as a useful supplementary cephalometric indicator for assessing vertical growth patterns in skeletal Class I malocclusion.
