Dental prosthesis and component thereof

Abstract

This invention provides a measure that makes it possible to prevent more effectively, in comparison with the prior art, the invasion of germs from the gap between a dental prosthesis and the gingiva when the dental prosthesis is used in an oral cavity as well as the infection and inflammation associated therewith. There is a dental prosthesis or a component thereof, characterized in that: the dental prosthesis or the component thereof has hydroxyapatite fine particles on a surface of the dental prosthesis or the component thereof; the hydroxyapatite fine particles are sintered bodies; and the hydroxyapatite fine particles have a mean particle size of 10 to 1,000 nm.

1 . A dental prosthesis or a component thereof, wherein
 the dental prosthesis or the component thereof comprises hydroxyapatite fine particles on a surface of the dental prosthesis or the component thereof,   the hydroxyapatite fine particles are sintered bodies, and   the hydroxyapatite fine particles have a mean particle size of 10 to 1,000 nm.   
     
     
         2 . The dental prosthesis or the component thereof according to  claim 1 , wherein the dental prosthesis is an implant that is an artificial dental root to be embedded in a bone in an oral cavity, and the component is an abutment used for the implant.
