Summary
Surgically assisted rapid maxillary expansion corrected a retrognathic maxilla and unilateral crossbite in an adult patient. This orthodontic surgery improved function, aesthetics, and speech, achieving a satisfying outcome.
Area of Science:
- Dentistry
- Orthodontics
- Maxillofacial Surgery
Background:
- Adult patients with a retrognathic maxilla often present with complex functional and aesthetic challenges.
- Unilateral crossbite can significantly impact occlusal stability and facial harmony.
- Orthodontic surgery offers solutions for skeletal discrepancies impacting oral function and appearance.
Observation:
- A 46-year-old woman presented with a retrognathic maxilla, unilateral crossbite, and associated functional, aesthetic, and speech issues.
- The patient underwent unilateral surgically assisted rapid maxillary expansion (SARME) using a bone-borne transpalatal distractor.
- Post-operative orthodontic management included the use of a temporary anchorage device.
Findings:
- Unilateral SARME effectively addressed the maxillary deficiency and unilateral crossbite.
- The combination of orthodontic treatment and prosthodontic rehabilitation (composite veneers, crowns, removable partial denture) yielded positive results.
- The patient achieved a functionally and aesthetically improved outcome.
Implications:
- Surgically assisted maxillary expansion is a viable treatment option for adult patients with specific skeletal discrepancies.
- Multidisciplinary treatment involving orthodontics and prosthodontics can achieve significant functional and aesthetic improvements.
- Addressing skeletal issues in adults can resolve complex functional, aesthetic, and speech problems.
