Abstract
An orthodontic magnetic extrusion technique is described for the management of an
extensively damaged maxillary premolar. A cylindrical neodymium-iron-boron (Nd2Fe14B) magnet was attached to the remaining tooth structure, and a second magnet was placed
on a resin-bonded partial denture. A 4.5-mm extrusion was obtained after 3 adjustments,
and the tooth was prepared with a 3-mm buccal and 2-mm lingual ferrule by following
a biologically oriented preparation technique and restored with a monolithic zirconia
crown. Eighteen months after completing the treatment, no evidence of soft tissue
dehiscence, abnormal tooth mobility, endodontic failure, or root resorption was found.
