Magnetic attachments are third-generation attachments with various characteristics, and their application to implant-supported dentures has been attempted. This attachment is useful in overdentures for difficult cases such as edentulous jaw, cleft palate, and remarkable defect of jawbone.
This report describes an implant overdenture with milling bar attachment made of a goldplatinum alloy that has magnet keepers on the top face. The denture has a titanium frame in the permanent resin baseplate. This attachment has only retentive force, and support and bracing force are demonstrated with the milling bar.
We have treated 20 cases with this type of denture in 6 years and there was no experience of disintegrated implant, broken bar or remade denture. The advantages of this method based on our clinical experiences are reliable occlusal registration because of the ease of checking the metal frame adaptation on the bar, sufficient support with rigid bar, and easy removal for aged and/or handicapped patients, as well as ease and reliability of repair and relining.
