Depending on the patient's growth potential, the degree of malocclusion, and patient compliance, class II correction calls for different strategies. The aim is to evaluate the changes in the soft and hard tissues of the orofacial region using three distinct treatment modalities: camouflage, AMO, and en-masse distalization. Based on the treatment strategy used, 45 adult skeletal class II patient records were evenly divided into three clusters. FACAD software was used to trace lateral cephalograms before and after therapy. The Kruskal-Wallis test was used for intergroup comparisons and the Wilcoxon signed-rank test was used for intragroup comparisons. Significant changes were observed in the following areas: lower incisor-NB, lower incisor-APog Line, upper incisor-APog in all three groups, Max1-NA, Max1-APog, and interincisal angle in all three groups, Mand1-NB in group 1, and Mand1-APog in group 3. All groups showed a significant decrease in upper lip strain. Only in group 3 were there significant changes in the nasolabial angle (P-value = 0.01), upper lip angle (P-value = 0.002), and upper lip length (P-value < 0.001). The 3 groups' interlabial gaps changed significantly (P-value < 0.05). Comparison between groups showed significant differences in upper lip thickness, angle, strain, and interlabial gap. In conclusion, patients who received surgical treatment showed a significant decrease in interlabial, upper lip strain, upper lip angle, and lower lip thickness. Subjects receiving IZC anchoring showed a substantial increase in lower lip length. Patients who received surgical treatment had the greatest upper incisor retrusion, whereas those who received camouflage treatment showed a significant decrease in lower incisor inclination.
