What is Failure Mechanisms of Dental Magnets about?

The study investigated the failure mechanisms of dental magnets used for denture retention that had failed after 4 to 18 months of clinical use. The magnets consisted of neodymium-iron-boron magnets encapsulated in stainless steel and epoxy resin. Analysis found that the diffusion of moisture through cracks in the epoxy seal or breakdown of the encapsulating material led to corrosion of the magnets. This corrosion weakened the magnetic attraction and caused a loss of retention. The failures need to be addre
