Summary
Surgically assisted rapid maxillary expansion (SARME) using dental-anchorage devices can lead to vestibular bone loss and minor root resorption, primarily affecting molars. These findings highlight potential complications to monitor during orthodontic treatment.
Area of Science:
- Orthodontics
- Maxillofacial Surgery
- Dental Imaging
Background:
- Surgically assisted rapid maxillary expansion (SARME) with tooth-borne devices can cause complications.
- Quantifying these dentoskeletal changes is crucial for patient management.
Purpose of the Study:
- To quantify dentoskeletal changes after SARME using a tooth-borne device.
- Assess bone height, thickness, fenestrations, and root resorption.
Main Methods:
- Cone beam CT scans of 39 patients pre- and post-SARME.
- Analysis of vestibular bone height, bone thickness, fenestrations, and root resorption.
- Measurements at first upper premolar (P1) and first upper molar (M1) levels.
Main Results:
- Significant vestibular bone loss (height and thickness) observed, mainly in molar regions.
- Fenestrations noted at the apex of mesio-vestibular roots of first molars.
- Minor root resorption occurred on molar roots, with limited impact on premolars.
Conclusions:
- SARME with dental-anchorage devices is associated with vestibular bone changes and minimal root resorption.
- Complications are predominantly observed in the molar regions.
