Summary
Nonsurgical rapid maxillary expansion effectively treated transverse maxillary deficiency in 81.5% of adult patients. While some discomfort occurred, the procedure facilitated improved bite relationships.
Area of Science:
- Dentistry
- Orthodontics
- Maxillofacial Surgery
Background:
- Transverse maxillary deficiency is a common condition affecting adults.
- Nonsurgical rapid maxillary expansion (RME) is a potential treatment modality.
- Adult anatomy presents unique challenges for maxillary expansion.
Purpose of the Study:
- To evaluate the efficacy and morbidity of nonsurgical RME in adult patients with transverse maxillary deficiency.
- To assess the clinical outcomes and patient experience with a fixed Haas-type expander.
Main Methods:
- Thirty-eight adult patients with diagnosed transverse maxillary deficiency were included.
- A fixed rapid maxillary expansion appliance (Haas design) was used for treatment.
- Success was clinically assessed by the presence of a central incisor diastema.
Main Results:
- Successful maxillary expansion was achieved in 81.5% of the patients.
- Morbidity included mild discomfort to significant pain, edema, and palatal lesions, generally not hindering expansion.
- Moderate, yet satisfactory, maxillary expansion was achieved, improving interocclusal relations.
Conclusions:
- Nonsurgical RME using a fixed Haas expander is a viable treatment for adult transverse maxillary deficiency.
- The procedure demonstrates a high success rate with manageable morbidity.
- RME effectively improves occlusal relationships in this patient population.
