evaluation and comparison of lips, nose, chin and chin-throat angle in patients with different mandibular divergences

Introduction: In orthodontics, facial harmony is defined by the patient's soft tissue profile, which is controlled by morphologic connections and proportions of the nose, lips, and chin. Aim: To evaluate thickness of lips, nose, chin and chin-throat angle in different mandibular divergent patterns. Materials and method: Pre-treatment lateral cephalograms of patients aged 16-25 years were obtained they were determined horizontal or vertical growers on the basis of divergence of planes. The cephalometric measurements were obtained after tracing the cephalogram. Results: The intergroup contrast of all three groups were statistically significant for upper lip width (p=0.001) and lower lip width (p=0.001) the chin thickness was maximum in hypo divergent i.e. 11.07 ± 1.5. In norm divergent group 10.12 ± 1.8 and hyper divergent group 09.84 ± 2.2 Hypo divergent had the highest chin-throat angle (88.02° ± 3.01°), followed by norm divergent (86.44° ± 3.4°), and hyper divergent (78.74° ± 6.3°) Conclusion: Upper and lower lip thickness were maximum in hypo divergent and minimum in hyper divergent. Nose thickness was insignificant. Chin thickness was maximum in hypo divergent and least in hyper divergent. Chin-throat angle was maximum in hypo divergent and minimum in hyper divergent subjects.
