Clinical Trial Summary

Maintaining teeth in their corrected position after orthodontic treatment is one of the most challenging part of orthodontic treatment and hence a period of stabilization termed as retention is provided after orthodontic treatment. Retention is one of the most important phase of orthodontic treatment that attempts to keep teeth in the corrected positions after treatment with orthodontic braces.

Following literature search there is no scientific evidence for the timing of retainer delivery.The present study is designed to know if post orthodontic tooth movement vary with different time of retainer delivery and since there is unusual delay after debonding as the retainer is fabricated at the laboratory. Such a study will help us to find out within which time period the retainer should be delivered

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 in one group and post 3 days retainer delivery 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 ;
