Comparison of Canine Retraction Using Ni-ti Closed-coil Springs Vs Elastomeric Power Chains During Orthodontic Treatment
Sponsor: Munnal Gulzar
Summary
The objective of this study is to compare the canine retraction rate (in mm with a 100 mm marked scale) using Ni-Ti closed-coil springs versus elastomeric power chains during canine retraction in subjects with first premolar extractions over a period of three months. After the extraction of all first premolars under local anesthesia. For canine retraction, Ni-Ti closed-coil springs and elastomeric power chains will be randomly allocated to the right and left quadrants of both arches. Radiographic measurement (root resorption) and clinical measurements (canine retraction, plaque accumulation and gingival health) will be recorded at four points in time. First, at the start of the canine retraction (T0), after first month (T1), second month (T2) and third month follow-up (T3).

Interventions
Ni-ti Closed-coil Spring
Ni-Ti closed-coil spring is a passive compressed spring made up of super elastic Nickel-titanium. Two eyelets are attached to each side of the coil to facilitate its application. The eyelets will be engaged in the hooks of the second premolar and canine brackets and will apply a force of 150 gm.
Elastomeric Power chain
Elastomeric power chains are resilient and latex-free orthodontic materials. They are made up of elastic material and consist of many connected rings. Each ring is engaged in a bracket to apply a force of 175-300 gm.
