title: An analysis of complete and incomplete overbite in class II division 1 malocclusions (an analysis of overbite incompleteness).
abstract: A retrospective cephalometric study of Class II Division 1 malocclusions was carried out. Sixty patients with complete overbites were compared with another group of 60 matched in every respect, with the exception of having incomplete overbites. All patients were in the permanent dentition stage and aged between 10 and 14 years. An incomplete overbite was related to vertical variation in the skeletal pattern. This was demonstrated by greater anterior lower facial height, greater gonial angle, and steeper mandibular plane inclination. Incisor alveolar heights and molar heights did not vary between the groups. No differences between groups were noted for the degree of overjet reduction achieved during treatment, or in post retention relapse of overbite and overjet.
