Comparative evaluation of buccolingual inclination of posterior teeth in different malocclusions
Keywords:
buccolingual inclination, transverse discrepancy, crown inclinationAbstract
Objective: To compare the buccolingual inclination of maxillary and mandibular posterior teeth among Angle’s Class I, Class II div 1 and class II div 2 malocclusion. Materials and methods: The sample comprised lateral Cephalometric radiographs and Dental Casts of 90 subjects in the age group of 15-25 years. The sample was divided into 3 groups of 30 samples each. The first group comprised of records from 5 female and 25 male subjects with an average age of 20.67 years and showing Class I malocclusion. The second group comprised of records from 12 female and 18 male subjects with an average age of 20.03 years having Class II division 1 malocclusion and the third group of 18 male and 12 female subjects with an average of 20.63-years showing class II div 2 malocclusion. Results: Similar buccolingual inclination was seen in Class II div 1 and div 2 malocclusions for both maxillary and mandibular at premolar and molars. The buccolingual inclination in maxillary arch was found to be lowest in class I malocclusion for all the posterior teeth.
