3-D imaging of bone and root changes after moving a buccally displaced upper canine.
Three-Dimensional Evaluation of Alveolar Bone Changes and Root Resorption After Orthodontic Traction of Unilateral Buccally Displaced Maxillary Canines Using Two Different Techniques: A Randomized Clinical Trial
This trial tests two orthodontic traction methods to see which causes less bone loss and root shortening when fixing a buccally displaced upper canine.

What this trial studies
This interventional study uses cone-beam CT (CBCT) scans taken before and after orthodontic traction to measure three-dimensional changes in alveolar bone and root length of unilateral buccally displaced maxillary canines and adjacent teeth. Participants with a unilateral buccally displaced maxillary canine and a normally erupted contralateral canine will receive corrective traction using either a segmental T-loop or a piggyback NiTi double wire method. The CBCT results will be compared to the contralateral normal side and between the two traction techniques to quantify bone loss and root resorption. The trial focuses on patients with mild-to-moderate crowding who require fixed orthodontic treatment and excludes those with prior orthodontics, severe facial trauma, bilateral displacement, developmental anomalies, or systemic bone disorders.
Who should consider this trial
Good fit: Ideal candidates are Yemeni patients with a single buccally displaced maxillary canine, a normally erupted opposite canine, mild-to-moderate crowding, no sagittal discrepancy, and who need fixed orthodontic treatment.
Not a fit: Patients with bilateral canine displacement, previous orthodontic treatment, severe facial trauma, developmental dental anomalies, facial syndromes, or bone metabolism disease are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, the findings could help clinicians choose a traction method that preserves alveolar bone and reduces root resorption, lowering the risk of gingival recession and tooth compromise.
How similar studies have performed: Previous reports are mainly case series and comparisons of root resorption or periodontal outcomes after impacted canine traction, so randomized three-dimensional comparisons of these two traction methods are essentially novel.
