Summary
This study showcases successful orthodontic treatment for anterior crowding and deep overbite using mini-implants for incisor intrusion. The technique improved smile esthetics and occlusion without tooth extraction, with results maintained long-term.
Area of Science:
- Orthodontics
- Dental Implantology
Background:
- Anterior crowding, deep overbite, and gummy smile present complex orthodontic challenges.
- Traditional treatment may involve tooth extraction, impacting facial aesthetics.
Observation:
- A 19-year-old female patient presented with moderate lower arch length discrepancy, significant deep overbite (+7.2 mm), and gummy smile.
- Orthodontic mini-implants were utilized for anchorage.
Findings:
- Upper incisor intrusion using mini-implant anchorage corrected the deep overbite to +1.7 mm.
- Non-extraction alignment with an edgewise appliance achieved good occlusion and improved gummy smile.
- Treatment results were stable for two years post-treatment.
Implications:
- Mini-implant-assisted incisor intrusion offers a viable non-extraction alternative for correcting deep overbites and gummy smiles.
- This approach can enhance facial aesthetics and achieve stable occlusal outcomes.
- Effective management of complex malocclusions can be achieved with innovative anchorage solutions.
