Intruding upper front teeth using a utility arch plus small bone perforations
Official title: Evaluation of Dentoalveolar Changes Following Maxillary Incisor Intrusion Using Utility Arch Assisted With Micro-osteoperforations in Deep Bite Cases: A Randomized Clinical Trial
Run by Al-Azhar University · NCT07566676 · Data updated 2026-11-12
This study will test whether tiny bone perforations (micro‑osteoperforations) combined with a utility arch help move upper front teeth down in people aged 15–25 with a deep overbite.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are 15–25 years old with permanent dentition (excluding third molars), an overbite ≥4 mm, no prior orthodontic treatment, and good oral and periodontal health.
✕Probably not a fit
Patients with skeletal jaw discrepancies, missing or anomalous maxillary anterior teeth, existing root resorption, impacted canines, endodontically treated upper incisors, systemic conditions affecting tooth movement, or poor periodontal health are unlikely to benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Participants aged 15–25 with an overbite of 4 mm or more will receive maxillary incisor intrusion using a utility arch, with micro‑osteoperforations (MOPs) made through the gingiva into the cortical bone to stimulate remodeling. The MOPs are intended to increase local cytokine activity and bone resorption to speed tooth movement. Clinical and radiographic measurements will track dentoalveolar changes, intrusion amount, and signs of root resorption over the treatment period. Outcomes will compare tooth movement and root health following intrusion with the MOP‑assisted protocol.
Why it matters
Potential benefit: If successful, the approach could shorten upper‑incisor intrusion time and help limit unwanted root resorption.
How similar studies have gone: Micro‑osteoperforations are a relatively new technique and several clinical studies report modest acceleration of orthodontic tooth movement, though results on root resorption and long‑term benefit have been mixed.
