Abstract

Class II correction demands various approaches depending upon the patient’s growth potential, severity of malocclusion, and patient compliance. Aim is to evaluate the orofacial soft and hard tissue changes with three different treatment approaches namely enmasse distalization, AMO and Camouflage treatment. 45 adult skeletal class II patient records equally segregated into three clusters based on the treatment approach employed. Both pre-treatment and post-treatment lateral cephalograms were traced with FACAD software. Wilcoxon signed rank test for intragroup comparison and Kruskal Wallis test for intergroup comparison were done. Significant changes noted in the following: Max1-NA, Max1- APog, and Interincisal angle in all the 3 groups, Mand1-NB, in Group 1 and Mand1-APog in Group 3, Lower incisor-NB, Lower incisor-APog Line, Upper incisor-APog in all the 3 groups. Upper lip strain reduced in all groups significantly. Significant change was observed only in Group 3 in terms of upper lip length (p value <0.001), nasolabial angle (p value 0.01) and upper lip angle (p value 0.002). Interlabial gap showed significant change in all the 3 groups (p value <0.05). Intergroup comparison: Significant difference was noted in terms of upper lip strain, interlabial gap, upper lip angle and upper lip thickness. To conclude; Interlabial, Upper lip strain, upper lip angle and lower lip thickness reduced significantly in subjects treated surgically. Lower lip length increased significantly in the subjects treated with IZC anchorage. Upper incisor retrusion was highest in patients treated surgically and the lower incisor inclination reduced significantly in patients treated with Camouflage approach.
