Class II Division 2 is where the maxillary anterior teeth are retroclined and a deep overbite exists. The malocclusion was classified as Class II Division 2 characterized by the upright and retroclined position of upper central incisors in conjunction with excess vertical overbite and an excessive interincisal angle.

The Class II division 2 malocclusion occurs the least often and obtaining the sample for the purpose of evaluation has always remained a critical issue. Class II malocclusion. CLASS II Sub-division.

A Class II division 2 II2 relationship describes the malocclusion where. In Class II division 2 cases the upper central incisors are retroclined and the overjet usually minimal but may be increased.
