Advantages

• The housing is simply positioned within the denture base.

• From a biomechanical viewpoint magnetic retention places virtually no force on the implants.

Disadvantages

• The magnets corrode with time and need replacement on a regular basis.

• This type of retention provides no lateral stability to the denture.

Procedure

The implant attachment is placed in the normal way and the magnet within its housing is cured into the denture base either in the laboratory or at the chair side.
