Magnet retained mandibular overdenture: A multidisciplinary approach

Abstract

Magnets have been used widely in the field of dentistry for many years with some success, as they can be manufactured in small dimensions as retentive devices in overdenture technique, maxillofacial prosthesis, and obturators. These magnets are attached with remaining root structure or osseointegrated implants which transfer the occlusal load to the bone through the periodontal ligament of the retained roots, thereby prevent resorption of remaining alveolar bone proper and inter-radicular bone present around the roots. In this article, the use of magnetic assembly in fabrication of mandibular overdenture on retained roots and a conventional maxillary removable partial denture is discussed. Magnetic assembly consists of magnet and coping with a keeper on the remaining tooth structure since magnetic attachments can provide support, stability, and retention.Clinical Relevance to Interdisciplinary DentistryThe present article demonstrates the rehabilitation of partially edentulous patient with the help of magnetic assembly mandibular overdenture and maxillary conventional removable partial denture. Clinical presentation showed few remaining teeth in relation to the mandibular ridge. A multidisciplinary approach was adopted to retain the remaining teeth in the mandibular arch with the help of endodontic treatment (root canal treatment) followed by prosthetic rehabilitation.
