The correlation between histologic and radiological findings was studied afterimplantation of a composite (ß-FTC-C) into osseus defects which were experimentally inducedin 21 rabbits. Under general anaesthetic osseus defects were made in both femurs and filledin with a 4,5 x 6 mm composite cylinder. The animals were killed at the first week and,one, two, four and twelve months after surgery. X-ray study and microscopic examinationwere made in all the specimens. Troughout the implantation period, it was microscopicallyproven that the composite showed a progressive reabsortion process, mediated by cells ofmacrophagus lineage. A decrease in radiologic density and changes in its morphology werealso observed. At the end of the study (twelve months), limited traces of the material couldbe seen, in correlation with the images of the X-ray films which revealed the total absence ofthe composite implant.
