Facial harmony is achieved by both hard tissue and soft tissue of an individual. The aim of this study is to determine the lip thickness individuals with Angle's classI, Class II and Class III Malocclusion. To evaluate the variation in lip thickness among these three groups.
The material includes the lateral cephalometric radiographs of thirty individuals with ten in each group. Each group is further divided into five male and five female subjects with vertical growth pattern. The basic upper lip thickness was then measured according to the definition of Holdaway. The measured values were then subjected to statistical evaluation. RESULTS: The mean of groups 1, 2 and 3 were 14.2, 12.6 and 14.4 respectively. Oneway ANOVA shows a statistically significant correlation between the three groups with a signifance value of 0.013 (P<0.05). According to post hoc Tukey's HSD test, lip thickness in class2 individuals is significantly lower than the lip thickness in class 1 and class 3 individuals.
Within the limitations of the study, it could be concluded that the basic upper lip thickness of class II individuals is lower compared to class I and class III individuals.
