Brief Summary

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

Canine retraction after 1st premolar extracion into the extraction space is a routine treatment in orthodontics. Orthodontic patients requiring first premolar extraction, canine retraction and maximum anchorage were recruited for this randomized controlled trial. A search of the literature did not indicate the ideal frequency of elastomeric chain reactivation for optimum canine retraction. The study was approved by the ethical committee. The first premolars were extracted. Elastomeric chains were used to retract the canine distally into the 1st premolar space. The optimum reactivation interval was evaluated regarding the efficiency of treatment in terms of rate of canine retraction, canine tipping and rotation, root resorption and pain at the intervals of 2, 4, 6 and 8 weeks. Three dimensional imaging, as well as digital scanning were the methods for data collection.

Detailed Description

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

The canines, 2nd premolars, 1st molars and 2nd molars were bonded and banded. Leveling and alignment was achieved. After the first premolar extraction, temporary anchorage devices were inserted interradicular between 2nd premolar and 1st molar. Canine retraction was performed on a 0.016" X 0.022" stainless steel arch wire. A power arm was extended to apply the force closer to the center of resistance and achieve bodily movement. Elastomeric chains were calibrated to deliver a force of 150g and extended from the power arm to the mini screws directly. Recruited patients were randomly allocated to four groups according to the duration between the elastomeric chain reactivation. Canine reactivation intervals were 2, 4, 6, or 8 weeks. Cone beam computed tomography was performed before canine retraction and after 6 months of retraction. Digital dental casts were taken before canine retraction and monthly for 6 months.
