简要总结

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

详细描述

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.

盲法说明

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).

  • •Teeth in the buccal segments were without any gross anatomic root anomalies as determined by panoramic radiographs.
  • •There is no gross evidence of asymmetric bone loss in the buccal segments of a given arch as determined by panoramic radiographs.
  • •Crown/root ratios of contralateral canines and premolars are within 3 mm of one another as determined by panoramic radiographs.

排除标准

  • •Patients with growth and development problems.
  • •Evidence of bone loss.
  • •Presence of Impacted Canine.

研究组 & 干预措施

Elastic chains

Experimental

This side received maxillary canine retraction using elastic chains

干预措施: Elastomeric chain (Procedure)

Elastics

Experimental

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

干预措施: Elastics (Procedure)

结局指标

主要结局

Rate of maxillary canine retraction by elastics and elastic chains on each side

时间窗: Difference between pe and post retraction canine position during 15 weeks

The canine retraction rate was measured on superimposed digital casts of pre and post retraction models.

Measurement of the Tipping movement occurred by each method

时间窗: Pre and post retraction during 15 weeks

Tipping angle on each side was measured on Orthopantomograms (OPG).

Measurements of rotation resulted by elastic and elastic chain

时间窗: Pre and post-retraction during 25 weeks

The rotational angle was measured on each side by the digital models
