The aim of the present study is to evaluate Lateral Cephalometric norms in Chhattisgarh population by Burstone’s Analysis with the purpose of establishing normative standards, helpful in planning treatment of orthognathic surgery cases in this ethnic group. Sample size consisted of 200 subjects comprising 100 female and 100 male subjects (age group 18-25 yrs.) Subjects were included on the basis of the following inclusion criteria-1. Both male and female subjects aged between 18-25 years 2. Those subjects were selected who were belonging to the Chhattisgarhi Origin. 3. with acceptable facial profile and class I occlusion, normal overjet and overbite. Minimal amount of spacing and crowding were considered acceptable.4. With no history of prior orthodontic treatment. Kodac 800 orthopantomogram and Lateral Cephalometric Extra oral imaging system was used to take the digital lateral cephalograms of the subjects with functional head positioner, patients standing in natural head position. All the digital cephalograms were subjected to Burstone’s Hard tissue Analysis using Nemoceph software.,
Results indicate that both Chhattisgarh males and females compared to Caucasian counterparts have shorter cranial base length, greater facial convexity (which is non significant in males), greater, maxillary and mandibular skeletal prognathism, prominent chin, and decreased posterior divergence of the mandible. Decreased vertical height of maxilla anterioposteriorly, shorter lower face height, upper anterior and posterior dental heights as well as lower anterior and posterior dental heights. Decreased ramal height and mandibular body length less bony chin depth, steeper occlusal plane and increased sagittal base discrepancy and proclination of upper and lower incisors.
So analysing the Craniofacial morphology of Chhattisgarh face, it can be concluded that Chhattisgrh population has a face which is skeletally prognathic, vertically short, steep occlusal plane and bimaxillary protrusive as compared to Caucasians.
