Summary
Functional therapy using the U-Bow-Activator Type I effectively treats Angle class II subdivision 2 malocclusion. This approach stabilizes skeletal and dental improvements long-term.
Area of Science:
- Orthodontics and Dental Development
- Craniofacial Growth Modification
Background:
- Angle class II subdivision 2 malocclusion presents complex skeletal and dental challenges.
- Growth and functional therapy are critical in addressing such malocclusions.
Purpose of the Study:
- To analyze the long-term effects of U-Bow-Activator Type I therapy on Angle class II subdivision 2 malocclusion.
- To evaluate both skeletal and dental changes resulting from combined growth and functional therapy.
Main Methods:
- A cephalometric long-term study was conducted.
- The U-Bow-Activator Type I was utilized for functional therapy.
- Analysis focused on skeletal and dental outcomes.
Main Results:
- Therapeutic clockwise mandibular rotation was achieved with controlled maxillary positioning.
- Normal sagittal mandibular growth rates were successfully attained.
- Significant improvements in dental aspects of the malocclusion were observed.
Conclusions:
- Combined growth and functional therapy with the U-Bow-Activator Type I yields positive skeletal and dental outcomes.
- The observed improvements demonstrate stability in post-treatment follow-ups.
- This therapeutic approach is effective for Angle class II subdivision 2 malocclusion.
