| Abstract: | Recently there has been developed a raze earth/cobalt magnet which possesses exceptional magnetic properties and can be produced in a size suitable for intra-oral use. Preliminary studies have been directed to determine the most effective form of magnet design which could be used to improve denture retention. Breakaway loads of over 200 g have been recorded together with attractive forces of up to 50 g at air-gap separations of 2 mm. |
