Summary
This case report details successfully erupting a horizontally impacted canine using mini-implants and a modified Nance button. This orthodontic technique achieved a desirable, esthetic outcome with maintained gingival attachments.
Area of Science:
- Dentistry
- Orthodontics
Background:
- Maxillary canine impaction, especially horizontally impacted teeth, presents a significant orthodontic challenge.
- This case involves a 16-year-old male with retained deciduous canines and bilaterally impacted maxillary canines, one horizontally impacted with a high difficulty score.
Observation:
- The left maxillary canine was horizontally impacted on the labial side, classified as "difficult" treatment (Kau-Pan-Gallerano index score of 19).
- Initial treatment involved distal traction from reinforced anchorage to correct inclination before eruption.
Findings:
- A mini-implant and a modified Nance button-assisted forced eruption technique were employed for the impacted canine.
- A 12-month follow-up confirmed maintained results and intact gingival attachments for the erupted canine.
Implications:
- Conservative surgical exposure combined with well-planned biomechanics can achieve successful orthodontic alignment of deeply impacted canines.
- This approach offers a viable solution for improving smile aesthetics in challenging impaction cases.
