Abstract
Una matriz de implante óseo que comprende: a) una matriz base tratada con b) una mezcla de refuerzo como un recubrimiento homogéneo, finamente disperso en toda la superficie de la matriz, conteniendo dicha mezcla de refuerzo al menos un polímero y al menos un componente adicional seleccionado de nutrientes celulares, promotores del crecimiento celular, promotores de la adhesión celular, osteoinductores, osteointegradores, "sustancias beneficiosas para la célula": una sustancia que es capaz de promover el enraizamiento celular y el crecimiento celular, estimulando la proliferación celular y la integración tisular, en donde la matriz base es una matriz ósea bovina desmineralizada, no desmineralizada, descelularizada, el polímero de la mezcla de refuerzo es un poliéster biodegradable o copolímero del mismo, la "sustancia beneficiosa para la célula" se selecciona del grupo que consiste en gelatina, gelatina hidrolizada, y en donde la mezcla de refuerzo se obtiene partiendo de dos soluciones, cada una de ellas hecha de un polímero soluble, que es el poliéster biodegradable o copolímero del mismo, y un agente, que es la gelatina o gelatina hidrolizada, que promueven la implantación, crecimiento y proliferación celular, y la integración tisular, respectivamente, inmiscibles entre sí, pero hechas parcialmente miscibles añadiendo un alcohol u otro disolvente adecuado en cada una de ellas; con el fin de obtener una dispersión molecular fina y homogénea de los componentes.

Se añaden 10 ml de isopropanol a la solución de copolímero de PLA/PCL en diclorometano previamente preparada. Se mantiene la solución copolimérica así obtenida con agitación durante 20 minutos. Se añade la solución de gelatina, previamente preparada, a la solución copolimérica. Se mantiene la solución polimérica así obtenida bien agitada durante 10 min a temperatura ambiente, con el fin de
obtener una solución nanodispersa estable y bien homogénea de todos los compuestos usados.
Se sumerge la matriz ósea descelularizada, no desmineralizada bovina en la solución polimérica y se mantiene sumergida durante al menos 30 min con agitación. Al final, se introduce el producto en el horno de vacío durante 24 horas a 37ºC (±2ºC) con el fin de eliminar los
disolventes. Ejemplo de realización 2C. Método para preparar una matriz de implante óseo Se pone en solución 1 g de copolímero de P(L,DL)LA en 20 ml de diclorometano. Se mantiene con agitación durante
al menos 45 minutos a temperatura ambiente con el fin de obtener una solución que tenga una dispersión muy
homogénea. Se sumerge la matriz ósea bovina en la solución polimérica y se mantiene sumergida durante al menos 30 minutos con agitación.
Se introduce el producto en el horno de vacío durante 24 horas a 37ºC (±2ºC) con el fin de eliminar los disolventes.
Se sumerge de nuevo la matriz previamente tratada en la solución polimérica y se mantiene sumergida durante al menos 30 minutos con agitación. Se introduce el producto en el horno de vacío durante 24 horas a 37ºC (±2ºC) con el fin de eliminar los disolventes. Se preparan 20 ml de solución al 1,5% de gelatina porcina hidrolizada. Se vierte agua, preferiblemente por
inyección, y se agita suavemente, se añade la gelatina porcina hidrolizada. Se mantiene con agitación durante al
menos 1 h a 37ºC (±2ºC) con el fin de obtener una solución caracterizada por una dispersión muy homogénea. Se añaden 10 ml de isopropanol a la solución de copolímero de P(L,DL)LA en diclorometano previamente preparada.
Se mantiene la solución copolimérica así obtenida con agitación durante 20 minutos. Se añade la solución de gelatina, previamente preparada, a la solución copolimérica. Se mantiene la solución polimérica así obtenida bien agitada durante 10 min a temperatura ambiente, con el fin de
obtener una solución nanodispersa estable y bien homogénea de todos los compuestos usados.
Se sumerge la matriz ósea descelularizada, no desmineralizada bovina, tratada ya dos veces, en la última solución polimérica y se mantiene sumergida durante al menos 30 min con agitación. Al final, se introduce el producto en el horno de vacío durante 24 horas a 37ºC (±2ºC) con el fin de eliminar los
disolventes. Ejemplo 3. Ensayos experimentales Se llevó a cabo el barrido con microscopio óptico de varios sustratos, usando el sistema ESEM Evo 50 EP de Zeiss-
Cambridge Instruments (Alemania). Todas las imágenes se obtuvieron con los mismos aumentos: 30X. Además, todas las imágenes se normalizaron en las mismas proporciones. La figura 1 muestra una imagen obtenida por el microscopio óptico de una capa de hueso cortical humano, que
presenta las características deseadas de porosidad y resistencia mecánica. La figura 2 muestra una imagen obtenida por un microscopio óptico de una matriz ósea desmineralizada bovina. En la estructura microscópica se pueden destacar diferencias notables con respecto a la capa de hueso cortical humano
(figura 1), en particular en relación con la porosidad. Esta última aparece mucho mayor y poco compatible con el enraizamiento celular. La matriz ósea desmineralizada bovina en la figura 2, que representa una “matriz base” de acuerdo con una
realización de la invención, se sometió a un tratamiento con una mezcla de refuerzo que contenía al menos un
