A simple and innovative low cost technique for fabricating magnet retained overdentures- A case report

Abstract

Various attachments have been used in overdentures to increase the retention. Application of rare earth magnets such as Sm-Co and Nd-Fe-B, for improving retention have been widely used in the field of prosthodontics, as they can be manufactured in small dimensions as retentive devices for complete dentures, removable partial dentures, obturators and maxillofacial prosthesis. However they are expensive as these attachments are not manufactured locally, so they increase the cost of treatment hence cannot be afforded by all patients. This article presents a simple and cost-efficient method of fabricating mandibular over denture retained by magnets in a patient whose mandibular residual ridge was severely resorbed with few remaining teeth and opposed by maxillary conventional removable partial denture.
