Magnetic Over Denture: Bidding Adieu to Clasped Removable Partial Denture

Abstract

Magnets have been used in prosthodontics for many years, but success has been limited because of their susceptibility to corrosion by the saliva and their retentive force is weak relative to the initial retention offered by mechanical attachments. More recently, magnets have been made from alloys of rare earth elements samarium and neodymium, which provide stronger magnetic force per unit size. In addition, a new generation laser welded containers has improved protection from salivary corrosion. The current resurgence of interest in this type of attachment appears justified because, unlike mechanical attachments, magnets have potential for unlimited durability and superior to mechanical ball or bar attachments for the retention of removable prostheses on implants. As the magnets can be manufactured in smaller dimensions, it can be used as retentive component in removable partial denture for rehabilitation in the esthetic zone, obturators, maxillofacial prosthesis and implant over dentures. The present article discribe the esthetic rehabilitation of partially edentulous gummy smile patient with the help of magnetic overdenture.
