Abstract

Background: The Class-II Division-1 (Cl-II Div-1) malocclusion is found with a vivid range of sagittal and vertical dento-skeletal components and the picture varies in each population. It is necessary for the orthodontist to locate the underlying morphology and decide the right treatment plan. Extensive research has been done to extract the underlying dento-skeletal picture of Cl-II Div-1 malocclusion in different populations but literature shows scarcity of such research in Gujarati population wherein Cl-II Div-1 malocclusion shows highest prevalence. Aims: The aim of this study is to assess various skeletal and dento-alveolar components of Class II Div-1 malocclusion in sagittal and vertical planes in local Gujarati population using cephalometric radiographs. Material and Methods: A sample of 184 participants of Gujarati origin was selected and their lateral cephalograms were traced and analysed for 18 dental and skeletal parameters and tabulated for statistics. Results: Mandibular retrognathism (87.5%) and horizontal growth pattern (64.13%) were found to be the major skeletal components comprising Cl-II Div-1 malocclusion in Gujarati population. Maxillary dental protrusion (89.13%) and maxillary incisor extrusion (72.28%) were found to be the major dental components. Conclusions: Cl-II Div-1 malocclusion comprises of varied dento-skeletal components. Maxillary retrusion, maxillary dental protrusion, mandibular retrusion and mandibular dental retrusion with horizontal growth pattern was found to be the most frequent dento-skeletal combination (23.37%) underlying the Cl-II Div-1 malocclusion in Gujarati population
