Abstract
The present invention relates generally to a denture attachment. More particularly, the present invention relates to a denture attachment, wherein a user can detachably fasten a first fastening part coupled to a denture to a second fastening part placed on top of a natural tooth's root or implant fixture by a simple operation, and furthermore, even when occlusal force is continuously applied to the denture, the applied force can be buffered by an elastic rib structure of the attachment itself. Consequently, it is possible to extend not only lifespan of the attachment, but also lifespan of the implant fixture or natural tooth's root, and to provide superior performance with a significantly smaller volume than existing attachments, while providing excellent durability.
