Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE ENDOPROTESIS, DONDE EL BLOQUE DE DATOS DE UN MODELO (10) ACTUAL TRIDIMENSIONAL DE LA ESTRUCTURA DE HUESO EXISTENTE DE UN PACIENTE ES ADQUIRIDO UTILIZANDO UNA EXPLORACION TOMOGRAFICA DE ORDENADOR. EN UN ORDENADOR EL MODELO (10) ACTUAL ASI DETERMINADO SE DIFERENCIA CON RESPECTO AL BLOQUE DE DATOS DE UN MODELO (14) TRIDIMENSIONAL GENERADO MEDIANTE EXPLORACION EXISTENTE EN TOMOGRAFIA DE ORDENADOR Y SE FORMA LA DIFERENCIA CON UN MODELO INTERNO DE ORDENADOR PARA LA ENDOPROTESIS. CON ESTE PROCESO Y A FIN DE REDUCIR EL TRABAJO REQUERIDO PARA LA ELABORACION DE LA ADAPTACION CORRECTORA DE LA ENDOPROTESIS Y PARA EVITAR ADAPTACIONES DEFECTUOSAS, LA INVENCION PROPONE QUE LOS BLOQUES DE DATOS DEL MODELO (10) ACTUAL Y EL MODELO (14) DE REFERENCIA SEAN CONVERTIDOS EN DATOS DE UNA SUPERFICIE LIBRE CAD GEOMETRICA DESCRIBIENDO LAS SUPERFICIES DE LIMITACION DE LOS MODELOS A TRAVES DE FUNCIONES DE RANURAS Y DE BEZIER ORIENTADAS HACIA PUNTOS DE SOPORTE Y SIENDO IMAGINADAS, SUPERPUESTAS, SOBRE EL MONITOR DE ORDENADOR, DE FORMA QUE LA IMAGEN SE UTILIZA PARA TOMAR SEGMENTOS POSTERIORES DE LA SUPERFICIE (11) DE LIMITACION DEL MODELO (10) ACTUAL MEDIANTE PUNTOS DE DESPLAZAMIENTO DEL SOPORTE HACIA EL VOLUMEN DEL MODELO (14) TEORICO.
