Magnetic retention in prosthetic dentistry.

Magnets are a popular method of attaching removable prostheses to either retained roots or osseointegrated implants. This paper reviews the development of magnets in dentistry and describes the different types of magnetic attachments that are available. The clinical applications of magnets in prosthetic dentistry are illustrated and future technological advancements indicated. Whilst different magnetic materials that mirrored the developing technology have been used, the main drawback to their use is the potential of corrosion of the magnetic material in the mouth. However, newly emerging technologies may provide a solution to this problem, allowing the continued use of magnets in prosthetic dentistry.
