Nonextraction treatment of Class II, Division 1 malocclusions

Nonextraction treatment of three different types of Class II, Division 1 malocclusions that focused on solving the imbalances of the dentofacial configuration have been presented. Diagnostic features encountered were anterior alveolar hyperplasia that required simultaneous maxillary incisor intrusion and retraction, severe mandibular crowding requiring functional alveolar arch development, and maxillary prognathism requiring distal movement of the maxilla and incisor retraction. Since many factors contribute to the makeup of various types of Class II, Division 1 malocclusions, orthodontic mechanics should address the specific needs of each patient.
