Clinical Trial Summary

Retention has been defined as "the holding of teeth following orthodontic treatment in the treated position for the period of time necessary for the maintenance of the result". Controversies regarding retention regime exist due to lack of high quality evidence regarding duration, type and timing of different type retainer.The present randomised controlled trial will be undertaken to assess the changes and compare if there is any difference in movement of teeth in post orthodontic treatment cases with immediate and delayed (post 7 days) delivery using beggs retainer and change in level of bone biomarker over 6 months period of retention .

Clinical Trial Description

The proposed study will be a prospective, non-pharmacological, single blind, randomized clinical trial to evaluate if there is a difference in transverse (X-axis), A-P(Y-axis) and Vertical plane(Z-axis) of dentition in two group of post orthodontic treatment patients with immediate retainer delivery(Beggs wrap around retainer ) in one group and post 7 days retainer delivery( beggs wrap around retainer) in other group of patients. The present study will be conducted in the Department of Orthodontic and Dentofacial Orthopedics, P.G.I.D.S, Pt. B.D Sharma University of health sciences, Rohtak. The study will be carried out after the institutional approval obtained from ethical committee. A sample size of 18 patients was calculated keeping confidence interval 95% with power 80%. Accounting for a 10% drop out rate, 20 patients will be enrolled in each group. Patient will be randomly allocated to the study group by a person not involved in the trial using computer generated randomization list. Changes in the tooth movement in transverse(X-axis), A-P(Y-axis), Vertical plane(Z-axis) will be compared in terms of intercanine width, intermolar width, overjet, overbite and contact point displacement between the two groups at following time intervals. These parameters will be charted at T0, T1, T2,T3 and T4 for each patient.Changes in the tooth movement in transverse(X-axis), A-P(Y-axis), Vertical plane(Z-axis) will be compared in terms of intercanine width, intermolar width, overjet, overbite and contact point displacement between the two groups at following time intervals. These parameters will be charted at T0, T1, T2,T3 and T4 for each patient. T0 - Baseline records, at the time of debonding. T1 - Records obtained at the time of retainer delivery. T2 - Records obtained after 1 month of retainer delivery. T3 - Records obtained after 3 months of retainer delivery. T4 - Records obtained after 6 months of retainer delivery ;
