Abstract

SE DESCRIBEN MATERIALES COMPUESTOS FORMADOS A PARTIR DE FIBRAS CERAMICAS O DE VIDRIO BIOACTIVAS OSEAS, Y FIBRAS ESTRUCTURALES. EN REALIZACIONES PREFERIDAS, UN TRENZADO O UN TAMIZ DE FIBRAS CERAMICAS Y DE VIDRIO BIOACTIVAS OSEAS INTERTEJIDAS SE IMPREGNA CON UN MATERIAL POLIMERICO, PARA SUMINISTRAR UN MATERIAL COMPUESTO CON UNA BIOCOMPATIBILIDAD ADECUADA Y UNA INTEGRIDAD ESTRUCTURAL. MAS PREFERIBLEMENTE, EL TAMIZ O EL TRENZADO SE DISEÑA DE FORMA QUE LAS FIBRAS BIOACTIVAS SE CONCENTRAN EN LA SUPERFICIE DEL IMPLANTE, PARA CREAR UNA SUPERFICIE FORMADA POR AL MENOS UN 30 % DE MATERIAL BIOACTIVO, SUMINISTRANDO CON ELLO UN CRECIMIENTO OSEO MEJORADO. EL ENTRETEJIDO ENTRE LAS FIBRAS CERAMICAS Y DE VIDRIO BIOACTIVAS OSEAS, Y LAS FIBRAS ESTRUCTURALES DEL NUCLEO, SOLUCIONA LOS PROBLEMAS ENCONTRADOS EN SISTEMAS COMPUESTOS ANTERIORES, EN LOS CUALES EL MATERIAL BIOACTIVO SE DESPRENDE EN FORMA DE LAMINA DEL POLIMERO. LOS MATERIALES BIOACTIVOS PREFERIDOS INCLUYEN CERAMICAS DE FOSFATO DE CALCIO, Y LAS FIBRASESTRUCTURALES PREFERIDAS INCLUYEN FIBRAS DE CARBONO. OTROS MATERIALES BIOACTIVOS PREFERIDOS INCLUYEN EL OXIDO DE ALUMINIO EN UNA CANTIDAD MAYOR QUE UN 0,2 % MOLAR. POR TANTO, TAMBIEN SE DESCRIBEN IMPLANTES PROTESICOS Y PROCEDIMIENTOS PARA FIJAR UN IMPLANTE MEJORADOS.
