Abstract
Disclosed herein is a novel implant material excellent in biocompatibility, stability in living body and mechanical properties, comprising a metallic material and a layer of a thermosetting resin or a layer of a composition comprising the thermosetting resin and hydroxyapatite, the layer of the thermosetting resin or the layer of the composition being formed around the metallic material.
Claims13
An implant material comprising a metallic material and a layer of a thermosetting resin thereon or a layer of a composition comprising a mixture of a thermosetting resin with hydroxyapatite particles therein, the thermosetting resin having excellent stability in a living body and being bicompatible, the layer of the thermosetting resin or the layer of the composition being formed around and adhered to the metallic material.
A biocompatible implant comprising a metallic core material having attached thereto as an outer coating a layer of a thermosetting resin composition, optionally with hydroxyapatite particles distributed therein, the thermosetting resin being stable in a living body and biocompatible with adjacent body tissue.
A biocompatible artificial tooth of a metallic core and an outer coating of thermosetting resin composition having an elastic modulus and hardness similar to a natural bone, the thermosetting resin composition containing a polymer of triethylene glycol dimethacrylate.
An biocompatible implantable artificial tooth of a metallic core and an outer coating of a thermosetting resin composition having an elastic modulus and hardness similar to a natural bone, the thermosetting resin composition containing a polymer of triethylene glycol dimethacrylate with particles of hydroxyapatite distributed therein, the weight ratio of thermosetting resin to hydroxyapatite in the range of 65:35 to 15:85.
