Abstract

Background:  The skeletal and dental anomalies that contribute to a malocclusion in a patient are very vital and the comprehensive knowledge of these components is required to design the treatment plan efficiently. Hence, the present study was planned to study the cephalometric characteristics of class II malocclusion patients reporting to department.  Material and methods: This study was conducted in the department of Orthodontics and Dentofacial Orthopedics of the Dental institute. For the study sample, we selected patients reporting to Outpatient department and were diagnosed with class II div 1 malocclusion. The age of the selected patients ranged from 7 to 13 years. A lateral cephalogram for each patient was done by a single operator. The distance of the subject from the X-rays source and distance at which film was kept was standardized and was kept same for all patients. For cephalograms, patients were directed to stand with natural head position, seated condyles and relaxed lips. A total of 30 patients were selected for the study of which 18 were females and 12 were males. For the tracing of cephalograms, a single operator was directed to do locate, identify and mark the points.  Results: From the results, it was observed SNA angle is significantly higher than normal value. On the contrary, SNB is significantly lower than normal. This states that subjects in our study have significantly more protruded maxilla and more retruded mandible.   Conclusion: From the results, this can be concluded that patient reporting to Departement of Orthodontics of the Dental institute with Angle’s class II, div 1 malocclusion have significantly increased ANB angle, decreased SNB, increased prognathism of maxilla with normal position of mandible.
