Overextrusion of maxillary molars usually results from early loss of antagonistic teeth due to caries or periodontitis. Conventional techniques for molar intrusion was used multiple teeth and extraoral devices, that depended highly on patient’s cooperation and usually result in extrusion of other teeth rather than posterior intrusion. This article reviews treatment consideration, force mechanics and side effects about miniscrews for intrusion of upper molars. We also present a clinical case to confirm miniscrew treat supra-erupted upper molars successfully.
