Magnetic attachment retainers, which used SUS 430 stainless steel produced by the machining method, were applied to implant treatment. In a patient for whom a denture was repeatedly fabricated because of its instability and detachment due to marked bone resorption after removal of maxillary subperiosteal implants, the amount of bone was confirmed by CT radiography after healing of bone,and then Integral® implants (right side; 3.25 mm in thickness, 6.0 mm in length, left side; 4.0 mm in thickness, 5.0 mm in length) were implanted into the bilateral molar areas. Magnetic attachment retainers were fixed to the implant fixture. A denture was fabricated by the routine method, and the magnetic alloy of HICOREX SUPER J® (right side; 3515, left side; 4015) was fixed to the inner surface of the denture with self-curing resin. No problems, including detachment of denture, were observed, and the patient was satisfied during denture application.
