Correction Of Posterior Crossbite In Adolescents And Young Adults With Class I , Class II And Class III Malocclusion

The study aims to to evaluate the association between age wise distribution of patients reported with posterior crossbite in Angle's class I, II, III malocclusion and to assess the percentage distribution of various treatment modalities in posterior crossbite in class I, class II and class III malocclusion in adolescents and young adults. A sample comprising 30 subjects with posterior cross bite undergoing treatment were selected. Within the limits of this study, the percentage distribution of treatment options was determined. The hyrax appliance remains the appliance of choice in 21.43% of patients in the age group of 10 to 14 years, 18.18 % of patients in the age group 15 to 19 years and bone borne anchorage being chosen for only 9.09 % of patients in the age group 15 to 19 years and 20% of patients in the age group of 20 to 24 years with the help of MARPE (miniscrew assisted rapid palatal expansion) appliance. Similarly another 40% of patients in the age group of 20 to 24 years underwent rapid palatal expansion assisted with surgical corticotomy. Fixed appliance arch expansion was another mainstay of treatment choice with 64.29% of patients in the age group of 10 to 14 years, 54.55% of patients in the age group 15 to 19 years and 40% of patients in the age group of 20 to 24 years of age with transverse discrepancies undergoing arch expansion with broad arch form arch wires. The results of this study will help the clinicians to decide the best treatment option for transverse discrepancies.
