Orthognathic surgery addresses transverse dimension issues in malocclusion. Treatment varies from orthodontic expansion to surgical maxillary expansion in adults, depending on patient needs and severity.
Area of Science:
- Orthodontics
- Maxillofacial Surgery
- Dentofacial Deformities
Background:
- Transverse dimension is crucial in orthognathic surgery.
- Treatment must be individualized based on patient factors.
- Adults often require surgical intervention for maxillary expansion.
Purpose of the Study:
- To discuss various treatment approaches for transverse dimension correction in orthognathic surgery.
- To outline indications, advantages, and disadvantages of different surgical techniques.
Main Methods:
- Review of orthodontic and surgical expansion techniques.
- Discussion of patient-specific treatment considerations.
- Analysis of segmental maxillary expansion indications.
Main Results:
- Orthodontic expansion is suitable for some cases.
- Surgical assistance is often necessary for adult maxillary expansion.
- Segmental maxillary expansion addresses severe deficiencies and complex deformities.
Conclusions:
- Comprehensive orthognathic treatment requires careful consideration of transverse dimension.
- Treatment selection depends on malocclusion severity, patient needs, and skeletal characteristics.
- Surgical options provide solutions for complex transverse discrepancies.
