Document Type and Number:
WIPO Patent Application WO2002102431
Kind Code:
A8
Abstract:
The invention relates to a metallic implant, which has vitreous-crystalline bioactive material on the surface thereof. According to the invention, a metallic implant base body arranged on the surface of the particles has a bioactive, vitreous-crystalline material consisting of 15-45 wt. % CaO, 40-45 wt. % P>25<, 10-40 wt. % ZrO>2< and 0.7-3.5 wt.- % fluoride, having apatite and calcium zirconium phosphate as main crystal phases and a glass phase as an auxiliary component. Said vitreous crystalline material contains at least 35 wt. % main crystal phases and at least 5 15wt. % auxiliary components. All of the percentage data is expressed in relation to the total weight of the vitreous crystalline material and the particle size of the vitreous crystalline material is between 60 - 350 mu m.
