Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical study aimed to evaluate the effectiveness of Elastics and Elastic chains in maxillary canine retraction. Participants of this study were patients undergoing maxillary canine retraction after first premolar extraction. The study aimed to determine an effective method for better controlling tooth movement.

This study was initiated on 01-2024. Initially, I was not aware of the importance of early registration on ClinicalTrials.gov. Registration was completed after the study began to ensure transparency and adherence to ethical guidelines. All study procedures and protocols have been conducted under the supervision of the academic advisor. All study procedures and protocols have been followed according to institutional and ethical guidelines

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This split-mouth Randomized clinical trial was conducted on 33 patients who needed maxillary canine retraction. Participants were randomly selected one side to receive an elastic chain and the other for elastics, as a method for canine retraction. The intervention period lasted for 15 weeks, and the elastics were replaced by the patient every three days, while elastic chains were exchanged by the principal investigator at 5-week appointments. The type of movement that occurred with each method was evaluated to measure the rate of tooth movement, tipping, and rotation resulting. The study was conducted under the supervision and approval of the Research Ethics Committee at Sana'a University, Faculty of Dentistry. All procedures were performed according to the approved protocol, ensuring participant safety and data accuracy.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

This study was designed as a split-mouth randomized clinical trial, where each participant received both interventions. One side of the maxillary arch was retracted with elastic chains, while the contralateral side received elastics. This design allows for direct intra-individual comparison between the two force delivery systems.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors

Due to the nature of the clinical intervention, neither the patients nor the investigator could be blinded to the treatment. However, researcher blinding was implemented at the data measurement stage through coding of OPG images and dental models by inter examiner, before measurements began. The researcher was blinded to patient identities and the type of retraction method used on each side (elastic chain vs. elastics).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Elastic chains

This side received maxillary canine retraction using elastic chains

Group Type EXPERIMENTAL

Elastomeric chain

Intervention Type PROCEDURE

Elastic chain used to apply force that is capable of canine retraction. The chains were attached between canine bracket and molar band on the side that selected Randomly.

Elastics

This side received maxillary canine retraction with Elastics on the contralateral side of the arch

Group Type EXPERIMENTAL

Elastics

Intervention Type PROCEDURE

Elastics were used to bring a continuous force for maxillary canine retraction in orthodontic patients. Elastics were stretched between the canine bracket and the molar band to retract the canine distally
