Modified Bone-borne MARPE Supported by a Flexible Template

The skeletal anchorage system has emerged with new possibilities in orthodontics, including the correction of maxillary transverse deficiency. The miniscrew-assisted rapid palatal expander (MARPE) is effective for widening the maxilla in adult patients. Among the various designs of MARPE, bone-borne MARPE is exclusively anchored on the palatal bone without any tooth support. Hence, it provides a pure orthopedic force without dentoalveolar side effects. This clinical pearl presents a simple modified bone-borne MARPE design with a clear, flexible template.
