Clinical Consideration on a Sandwich-type Dental Magnetic Attachment

Abstract

Our recent report of this study described the development of a small size and powerful dental magnetic attachment showing that it had cleared most clinical requirements, ascertained through many fundamental investigations. This article describes the clinical and laboratory procedures used with the system.
One of the elements;“keeper” is cast-weided to the metal-coping which is cemented on the decoronated tooth. Another element;“magnetic assembly” is fixed in the denture base fabricated in a usual manner, by using self-curing acrylic resin. Because of its minute size, this attachment can be used on almost any root-filled teeth.
A dentist has many choices in fabricating a denture with the magnetic attachment. He can set the metal-coping installed the keeper prior to the denture base construction; after the denture is completed; or simultaneously.
The magnetic attachment can be used weather singly, or with other conventional retainers such as the clasps or the telescope crowns. This system is simple; requires no special skills; and can be followed using standard equipment, materials, and techniques.
