Brief 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).

Outcome Measures
Primary Outcomes (1)
Canine retraction rate
The retraction rate of canine will be the distance travelled divided by the time interval needed for closure of spaces. It will be noted at four-time intervals i.e at the start of the canine retraction (T0), after first month (T1), second month (T2) and third month follow-up (T3).

Study Arms (2)
Ni-ti closed Coil spring
EXPERIMENTALFor canine retraction, Ni-Ti closed-coil springs will be randomly allocated to the right and left quadrants of both arches
Elastomeric power chain
ACTIVE COMPARATORFor canine retraction, elastomeric power chains will be randomly allocated to the right and left quadrants of both arches
Interventions
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 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.
Eligibility Criteria
You may qualify if:
- Patients aged between 13 - 40 years
- Patients undergoing fixed orthodontic treatment
- Patients requiring all first premolars extraction as part of orthodontic treatment
- Patients with all permanent teeth present and erupted (except for second and third molars)
- All patients who will sign the informed consent/assent form
You may not qualify if:
- Patients with systemic diseases that can affect tooth movements
- Patients with uncontrolled periodontal disease
- Patients with craniofacial syndromes
- Pregnant or lactating mothers
- Patients with bracket failures greater than three times per bracket during the study
- Patients on medications that can affect tooth movements
- Patients with Nickel allergy
