Dental magnetic attachment and its fixing method including spacer

Abstract

A dental magnetic attachment having good cushioning properties against a compressing pressure which makes a denture sink appropriately on biting. The dental magnetic attachment embedded in the denture base for holding the denture in the oral cavity by a magnetic attractive force working with the magnetic assembly and a soft magnetic keeper embedded in the top of the root surface includes a magnetic assembly and a cap covering the top of the magnetic assembly. The magnetic assembly has a hollow in the center of its top. The cap with a button is placed on the magnetic assembly, inserting the button into the hollow to contact to its bottom. On biting, the button is compressed, to be deformed with a shorter thickness and at this time a sleeve formed as a body around the core slides down along the side of the magnetic assembly to reduce the thickness of the dental magnetic attachment. This sliding makes the denture sink uniformly and appropriately. The dental magnetic attachment has good cushioning properties and offers a good feeling to a patient when biting with the denture.
