RETENTION DEVICE FOR DENTURES AND THE LIKE

摘要

RETENTION DEVICE FOR DENTURES AND THE LIKE A releasable magnetic retention device having two opposed substantially like units each of which has a relatively small permanent magnet of opposed poles, one pole of which is utilized with a conductor of low coercivity material to form a larger magnetic flux field in the conductor so that when the two like units are placed in magnetic attracting relation the two conductors complete a strong enlarged magnetic flux path between them to releasably retain the units together.
