Diagnosis and treatment of class II division 2 malocclusion.

Class II, Division 2 malocclusions often have skeletal patterns more nearly approaching Class I than Class II, Division I. Incisor relationships are unique. Treatment problems related to this malocclusion require that the clinician pay particular attention to the vertical dimension. Also, the prevalence of mandibular movement pattern irregularities, coupled with the "droopy incisor" phenomenon so characteristic of this malocclusion, requires careful individual case analysis. The use of simplified initial appliance mechanics to rectify some of these problems is discussed.
