Abstract:

Magnetic attachments are widely used for prosthodontic treatment. Comparing to conventional attachments utilizing mechanical friction, advantage of magnetic attachments include the lack of visible metal frameworks, simplified tooth preparation, and less traumatic lateral force. One of the problems that limited their wide acceptance to clinicians was the low corrosion resistance of the permanent magnet alloy. Recently, development of new magnetic materials as well as improvement of corrosion resistance of magnet has facilitated the application of magnetic attachment.

Key words: magnetic attachment, corrosion, Fe-Pt alloys
