Summary:
In young adults with transverse and anteroposterior maxillary deficiency, modified ALT-RAMEC protocol combined with MARPE significantly enhanced circummaxillary suture displacement and dentoskeletal effects with more favorable molar movement compared to conventional MARPE protocol alone, though it was associated with no specific adverse effects reported.
| PICO | Description |
|---|---|
| Population | Young adults (mean age 21.3 years) with transverse and anteroposterior maxillary deficiency. |
| Intervention | Modified 7-week Alternate Rapid Maxillary Expansion and Constriction (ALT-RAMEC) protocol combined with Mini-screw Assisted Rapid Palatal Expansion (MARPE). |
| Comparison | Conventional MARPE expansion protocol without the ALT-RAMEC modification. |
| Outcome | Both groups achieved 100% expansion efficiency. The ALT-RAMEC group demonstrated significantly greater displacement and widening of mid-palatal, frontonasal, intermaxillary, and zygomaticomaxillary sutures (p < 0.001), and more bodily tooth movement with less molar tipping compared to conventional MARPE. No major side effects were observed. |
