MSE-2 Maxillary Skeletal Expander – Refill Kit (Dr. Won Moon)The MSE-2 Refill Kit by Dr. Won Moon is one of the most advanced MARPE systems available, designed for predictable, stable, and non-surgical maxillary expansion in teens and adults.The MSE-2 features a unique skeletal anchorage concept with bicortical engagement, delivering maximum expansion force directly to the maxilla while minimizing unwanted dental tipping. Its rigid stainless-steel body ensures stability throughout treatment.The expander can be fixed in two ways:
Standard banded fixation – using molar bands, just like with conventional expanders made in the lab.
Digital workflow fixation – with a 3D-printed surgical guide, enabling precise and minimally invasive placement.This flexibility allows orthodontists to integrate the MSE-2 into both traditional and fully digital treatment protocols.Available in screw body sizes: 8 mm / 10 mm / 12 mm.
Fixation screw options: 9 mm / 11 mm / 13 mm.The Refill Kit contains everything needed for a new case, including the expander, fixation screws (in the chosen length), activation key, and patient safety elastics.
