Comparative evaluation of transverse discrepancies in different sagittal malocclusions-An observational study
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2018, Vol 4, Issue 1
Abstract
Introduction Successful orthodontic treatment outcome depends on an accurate diagnosis along with clinical management of vertical and transverse discrepancies Thus this study is carried out to evaluate dental arch and alveolar width along with buccolingual inclination of maxillomandibular teeth in different malocclusionsMaterials and Methods Based on the Anglersquos classification of malocclusion 140 study models were selected and four separate groups were formed normal occlusion Class I malocclusion Class II division 1 and Class II division 2 respectively Maxillomandibular arch and alveolar widths at canines 1st and 2nd premolars and first molars were measured Buccolingual inclination of posterior teeth were measured Lateral cephalogram of all the sample subjects was taken to calculate SNA SNB ANB angle Wits Appraisal and McNamara Differential Oneway Anova test was performedResults Maxillary intercanine interpremolars intermolar and maxillary dentoalveolar width is more in normal occlusion when compared with Class I Class II division 1 and Class II division 2 malocclusions Class II division 1 has narrower intercanine and interpremolar width with similar intermolar width as compared to Class II division 2 For transverse discrepancy buccolingual inclination is fundamentalConclusion Class II division 2 has a smaller arch width and Class II division 1 shows a significantly larger arch width than Class I malocclusionsKeywords Arch width Alveolar width and Buccolingual inclination
