Summary
This study explores surgical alteration of occlusal plane angulation in orthognathic surgery. It details techniques for both clockwise and counterclockwise rotations, analyzing their functional and esthetic outcomes and long-term stability.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
- Facial Esthetics
Background:
- Orthognathic surgery corrects jaw deformities, often involving occlusal plane adjustments.
- Clockwise rotation of the occlusal plane is a standard procedure.
- Counterclockwise rotation of the occlusal plane is less established but explored herein.
Observation:
- The article examines functional and esthetic traits of low and high occlusal plane facial types.
- Surgical methods for modifying occlusal plane angulation are detailed.
- Long-term stability of both clockwise and counterclockwise rotations is assessed.
Findings:
- Clockwise rotation of the occlusal plane is a well-accepted orthognathic surgery technique.
- Counterclockwise rotation, while less common, is presented as a viable treatment approach.
- The study analyzes the functional and esthetic results and long-term stability of both rotational directions.
Implications:
- This research provides insights into surgical correction of occlusal plane deformities.
- It expands treatment options for patients with specific facial types and occlusal plane angulations.
- Understanding the stability of counterclockwise rotations can improve orthognathic surgery outcomes.
