Local vitamin D3 plus corticision to speed up upper canine movement

Assessment of the Locally Administrated Vitamin D3 and Corticision Efficacy on Orthodontic Canine Retraction: A Prospective Clinical Study

Not applicable Interventional Al-Azhar University · NCT07455656

This test will try to see if locally applied vitamin D3 together with a minor bone-cutting technique called corticision can speed upper canine retraction in 13–20-year-olds having their upper first premolars removed.

What this trial studies

This is a prospective clinical study of adolescents and young adults (ages 13–20) who require bilateral maxillary first premolar extraction and orthodontic canine retraction. Participants will receive local application of vitamin D3 combined with corticision during the retraction phase, and measurements of canine movement and alveolar bone changes will be taken over time. Outcomes will be compared using an independent t-test or a nonparametric equivalent to determine differences in rate of movement and bone response. Safety and any adverse effects will also be monitored throughout follow-up.

Who should consider this trial

Good fit: Ideal candidates are healthy patients aged 13–20 with fully erupted permanent teeth who need bilateral maxillary first premolar extractions (for example, Class II division 1 with crowding or bimaxillary protrusion) and have not had prior orthodontic treatment.

Not a fit: Patients with impacted canines, severe crowding, untreated decay or endodontic lesions, or systemic diseases or medications affecting tooth movement (such as thyroid, parathyroid, renal, or liver disorders) are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, the approach could shorten orthodontic treatment time and reduce complications linked to longer appliance wear.

How similar studies have performed: Previous randomized trials have shown that vitamin D can accelerate canine distalization and influence alveolar bone density, while the combination of vitamin D with corticision is less well studied and is relatively novel.
