Summary
A new bone-borne palatal expander offers a successful alternative for treating transverse maxillary hypoplasia. This self-retaining device, used with surgically assisted palatal expansion, showed no relapse after 12 months.
Area of Science:
- Orthodontics
- Maxillofacial Surgery
- Dental Devices
Background:
- Transverse maxillary hypoplasia presents challenges in orthodontic treatment.
- Conventional tooth-borne expanders may have limitations.
- Surgically assisted palatal expansion is a common treatment modality.
Purpose of the Study:
- To evaluate a bone-borne self-retaining palatal expander for treating transverse maxillary hypoplasia.
- To compare this device with conventional tooth-borne expanders.
- To assess its efficacy in conjunction with surgically assisted palatal expansion.
Main Methods:
- Ten patients with transverse maxillary hypoplasia were included.
- Surgically assisted palatal expansion was performed.
- A bone-borne self-retaining palatal expander was inserted.
Main Results:
- All patients achieved adequate transverse expansion.
- Expansion was symmetric in nine out of ten patients.
- No transverse relapse was observed at 12 months postexpansion.
Conclusions:
- Bone-borne self-retaining palatal expanders are a viable option for surgically assisted palatal expansion.
- This device provides an effective alternative to conventional palatal expanders.
- The technique demonstrates stable long-term results.
