Summary
This case report details successful functional appliance therapy for isolated mandibular condyle aplasia in a young girl, correcting asymmetry and promoting condylar growth. The treatment achieved stable results without relapse over seven years.
Area of Science:
- Dentistry
- Orthodontics
- Craniofacial Biology
Background:
- Isolated mandibular condyle aplasia is a rare congenital condition.
- Early diagnosis and intervention are crucial for managing craniofacial asymmetry.
Observation:
- A 6.5-year-old girl presented with mandibular asymmetry due to aplasia of the mandibular condyle.
- She had Class II molar relationships, 5mm overbite, 5mm overjet, and a 3mm lower midline discrepancy.
- Classified as Pruzansky-Kaban type IIA and Vento M2B.
Findings:
- Treatment involved a modified Haupl-Andresen activator to guide mandibular repositioning.
- Functional appliance therapy lasted approximately 4 years.
- Significant condylar growth was observed on the affected side, with stable correction of asymmetry maintained for 7 years post-treatment.
Implications:
- Functional appliance therapy can effectively treat isolated mandibular condyle aplasia.
- This approach promotes condylar growth and corrects asymmetry, leading to stable long-term outcomes.
- Highlights the potential for non-surgical management in specific craniofacial deformities.
