Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients undergoing fixed mechanotherapy with upper first premolar extractions requiring 5 mm or more of maxillary canine retraction. 2. Presence of full complement of teeth except third molars. 3. Fair oral hygiene.
Exclusion criteria
Exclusion criteria: Patients presenting with: 1. Previous history of orthodontic treatment. 2. Medical or systemic problems. 3. Active caries, pulpitis or periodontal disease. 4. Severe crowding (>=6mm) or severe cant of the maxillary skeletal base or palatal plane (inclination angle = 95 degrees and base plane angle =40 degrees) simultaneously existing with severely divergent or convergent facial planes (Bjork sum 400). 5. Patients exhibiting microdontia or less than 5 mm of space available for canine retraction.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Mean rate of canine retraction per month, until 2 mm or less space is present distal to canine. Measured intraorally using a digital calipers. Measured as: residual extraction space between lateral incisor (disto-gingival wing of the bracket) and canine (mesio-gingival wing of the bracket); in mm; then expressed as [(space T0-space T1)/time T0-to-T1] in mm/month. Measured by: a calibrated person, fully blinded to experimental/control side (an orthodontist).Timepoint: Measurement timing: at baseline (before space closure), at 1-month intervals; end at space closure finalization (2 mm or less space remaining distal to the canine). | — |
Secondary
| Measure | Time frame |
|---|---|
| â?¢Cumulative canine distal movement measured in mm, on pre and post dental casts. â?¢ Canine and molar rotation, tip, root resorption,bone density in HU, and alveolar bone loss to be measured on CBCT scans. â?¢ Any scars from MOPs, tooth discoloration, devitalisation or gingiva invagination will be noted. Discomfort level on VAS scale.Timepoint: At T0 and Tfinal, except, discomfort level which will be measured daily after the intervention for a week. | — |
