Abstract

LA INVENCION SE REFIERE A LA ESTRUCTURA DE UN RECEPTACULO COMPUESTO DE UNA ENDOPROTESIS PARA ARTICULACIONES. LOS COMPONENTES INORGANICOS DEL RECEPTACULO TIENEN FASES CRISTALINAS DE APATITO Y/O DE WOLLASTONITA Y ADICIONALMENTE FASES CRISTALINAS SECUNDARIAS QUE PROPORCIONAN UNA ESTABILIDAD A LA HIDROLISIS MAYOR. LA MEZCLA INORGANICA CONSISTE (EN PROPORCIONES DE MASA EN %) EN 31-34% DE CAO, 10-12% DE P SUB 2 O SUB 5, 43-46% DE SIO SUB 2, 3-5% DE NA SUB 2 O, 2-3% DE CAF SUB 2 Y, PARA LLEGAR AL 100%, 0,5-11% AL SUB 2 Q Y/O ZR SUB 2 Y AL SUB 2 O SUB 3 O TIO SUB 2 Y ZRQ SUB 2 Y ZRO SUB 2 Y AL SUB 2 Q TAMBIEN, CON LO QUE LA PROPORCION DE TIO SUB 2 ES DE UN 0,5 A UN 5%. ALGO ESENCIAL A LA INVENCION ES TAMBIEN UNA CIERTA DISTRIBUCION DEL TAMAÑO DE PARTICULAS Y RELACION DE APERTURA ENTRE LA BOLA Y EL RECEPTACULO. EL RESULTADO ES UN FUNCIONAMIENTO SIN DETERIORO DE LA ENDOPROTESIS.
