A study testing immediate orthodontic retainer delivery and delayed orthodontic retainer delivery. in people with Relapse, run by Postgraduate Institute of Dental Sciences Rohtak at 1 site in India.
Trial summary
Orthodontic treatment goals can be expressed as achieving ideal tooth alignment, esthetic, functional occlusion and stability. Various occlusal changes occur after active phase of orthodontic treatment, these unwanted changes are called relapse. Read more about this study

About this study
Official title: "Comparative Evaluation of 3 Dimensional Changes of Dentition in Post Orthodontic Patients With Immediate vs Delayed (Post 24 Hours) Retainer Delivery-A Randomized Control Trial"
Orthodontic treatment goals can be expressed as achieving ideal tooth alignment, esthetic, functional occlusion and stability. Various occlusal changes occur after active phase of orthodontic treatment, these unwanted changes are called relapse. Reitan pointed out that major percentage of changes following active phase of treatment is seen within 24 hours.
To alleviate the effect of relapse, retention is needed. There is little agreement among clinicians about orthodontic retention protocol due to insufficient evidence in the literature on 1. time of retainer delivery 2. unexpected post- treatment changes. 3.quantification of relapse tendency.

The present study will be undertaken to assess the changes and compare if there is any difference in the movement of teeth in post orthodontic treatment cases with immediate and delayed (post 24 hours) retainer delivery.
Thus help in deciding when should the retainer delivery is preffered.
Read the detailed description
The proposed study will be a prospective, non-pharmacological, single blind, randomized clinical trial to evaluate if there is a difference in transverse (Xaxis), 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 24 hours 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(Zaxis) 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.

Questions about this trial
What is this clinical trial studying?
A study testing immediate orthodontic retainer delivery and delayed orthodontic retainer delivery. in people with Relapse, run by Postgraduate Institute of Dental Sciences Rohtak at 1 site in India.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 30 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Manisha Kamal Kukreja, MDS (9215650617 ext. 91, mk3pgids@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overjet (time frame: T0 - baseline on the day of debonding). The study lists 25 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 May 2023.
