Clinical Tips of Successful Maxillary Expansion with Mini Implants
Cho Jin-Hyoung

Abstract
Patients with severe dental crowding or transverse disharmony between the maxilla and mandibular arches required
expansion of the maxilla. In the past, there were several methods to expand the maxillary arch such as removable, fixed
appliances, or surgery. Recently, mini-implants have been used as a new orthodontic technique to expand the maxilla
in difficult cases. Microimplant-assisted rapid palatal expander (MARPE) was introduced as an alternative to surgically
assisted rapid maxillary expansion (SARME). In this article, three cases using maxillary skeletal expander (MSE, a
specific type of MARPE) and clinical tips (additional mini-implants, corticotomy and cortipuncture) that increase the
success rate of these appliances are presented.
