Summary
Autotransplantation of premolars successfully treated a young patient with multiple missing maxillary teeth due to regional odontodysplasia. This approach preserved natural teeth, promoting healthy bone and gum development.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Multiple missing maxillary teeth in growing patients present a significant orthodontic challenge.
- Regional odontodysplasia is a rare developmental anomaly affecting tooth formation.
Observation:
- A case report details the multidisciplinary treatment of an 11-year-old girl with regional odontodysplasia and missing maxillary incisors and canine.
- Autotransplantation of mandibular second premolars was performed to address the missing teeth.
Findings:
- The transplanted premolars were reshaped and restored with resin composite, integrated with orthodontic space closure.
- Gingivectomy achieved symmetrical gingival contours, resulting in successful space closure and natural tooth retention.
- Autotransplantation facilitated alveolar bone growth, normal interdental papilla formation, and adaptation to functional stimuli.
Implications:
- Autotransplantation offers a viable alternative to prosthetics or dental implants for managing complex tooth agenesis.
- This technique promotes long-term survival and functional integration of natural teeth in growing patients.
- Multidisciplinary care is crucial for optimizing outcomes in complex pediatric dental anomalies.
