Abstract

Introduction: Class II Div 1 discrepancy forms a major chunk of malocclusions, especially in countries like Pakistan. It is imperative to understand the underlying skeletal pattern of Class II Div 1 malocclusions and severity of its discrepancy in selecting the right treatment modality. Hence the aim of this study was to find out the underlying pattern of sagittal discrepancy in Class II Div 1 malocclusions and to know about its severity.

Material and Methods: The study was conducted on 103 patients, with convex profiles as judged by orthodontists in consensus. Lateral cephalogram was taken for each patient and traced for SNA and SNB. ANB angles were analyzed to determine the severity.

Results: 52.4% of class II Div 1 patients exhibited short mandible as the primary area to be addressed. Another 21.3 % of the patients showed short maxilla but mandible was further short again needing mandibular treatment only. 19.4% of the class II Div 1 patients however showed prognathic maxilla.  Majority of the class II Div 1 patients had either mild (ANB>4<7°) or moderate skeletal discrepancy (ANB>7<9°).

Conclusions: It is thus concluded that the sagittal pattern and severity of Class II Division1 malocclusion is empirical to understand for formulating a desirable treatment plan.
