Class III treatment by combining facemask (FM) and maxillary skeletal expander (MSE)

Among countless designs of MARPE, the Maxillary Skeletal Expander (MSE) has unique features that produce unique treatment results. MSE causes expansion of the entire midface, disrupting all perimaxillary structures. When MSE is applied in combination with FM, almost negligible vertical side effects are observed, the existing antero-posterior dental compensation can be reversed, the maxilla advances efficiently in large magnitude, and the skeletal protraction is possible even in older growing patients. Combining FM and MSE has also resulted in some skeletal protraction even in mature patients, simulating distraction-like movement, which gives hope of discovering a novel non-surgical orthopedic treatment modality for Class III adult patients.
