초록
This paper reports on a clinical case of craniofacial displacement from treatment with a Right Angle Maxillary Protraction Appliance (RAMPA). A seven-year-old girl was treated over 17 months using VomPress (4 months) and Hybrid (13 months) intraoral devices with RAMPA. Finite Element Analysis (FEA) simulations of a skull model with all sutures and validated material properties supported clinical findings. RAMPA produced an anterosuperior maxillary shift, counterclockwise mandibular rotation (−1.0°), and a 2.9° clockwise decrease in RAMUS angle. Both clinical and FEA results show RAMPA with Hybrid enhances maxillary protraction while minimizing downward displacement of the mid-palatine suture.
