Background: Class II Div 2 malocclusion is discussed as having short face patterns with occlusal and dental features which includes deep overbite, minimal overjet, tendency toward vertical displacement of maxillary incisors, lingual flexion of mandibular incisors, increased curve of spee, no exposure of the anterior maxillary teeth at rest and limited tooth exposure on smiling. The main aim of the study was to assess the severity of short face patternin untreated class II Div 2 malocclusion. Materials&Method: A total of twenty pre-treatment records such as study models, photographs and lateral cephalograms of patients with classII Div 2 malocclusion with age ranging from 10-15 years were obtained from the Dept. of Pedodontics& Preventive Dentistry, Government Dental College and Hospital, Hyderabad and were analysed for the dental& skeletal characteristics of class II Div 2 malocclusion. Results: In all the cases deep overbite is common with the incisal edges of the lower incisors contacting the soft tissues of palate is seen in few casesand in few cases the mandibular labial gingival tissues are also traumatized by the lingually inclined maxillary incisors. In cephalometric analysis, all the subjects were having smaller mandibular plane angle, smaller gonial angles & more retroclined maxillary incisors. Conclusion: Angles class II Div 2 malocclusion has a marked horizontal growthpattern with decreased lower facial thirds leading to short face pattern, which will limit the socialization of the individual and the deep bite which is most common in all class II Div 2 cases. If untreated will lead to severe attrition of lower incisors & recurrent lacerations of the palatal tissues.
