CONCLUSION
maxillary incisors, malocclusion, mandibular incisors, overjet
LIP
The null hypothesis of this study was rejected. Management by extraction of premolars is a better treatment modality than functional treatment for managing skeletal Class II division 1 malocclusion in Class II subjects with moderate skeletal discrepancy, increased overjet, protruded maxillary incisors and protruded lips.
Both treatment modalities resulted in significant dentoalveolar changes; however, inclination of maxillary as well as mandibular incisors was better maintained in premolar extraction treatment. Lip position relative to nose and chin, as well as nasolabial angle, improved significantly in maximum anchorage premolar extraction treatment cases.Extraction treatment resulted in significant improvement of soft tissue profile.
