How can be the bone reconstructed?Synthetic materials The bone can be reconstructed with synthetic materials for example calcium phosphate. Advantage of these materials are for example the exclusion of the transmission of virus infections like Creuzfeldt-Jacob disease (CJD). Disadvantage is the increased absorption of the developed volume during the transformation, i.e. during the transformation in own bone material. Animal bone materials Animal bone can be used from horse or cow. In this group it must be paid attention to the fact that the antigen structures are destroyed by a thermal process. Otherwise exists the danger of an antigen-antibody reaction, which rejects the bone material. Human bone materials Human bone, which is won by body donors. Also in this group exists the transmission risk of prions. The transmission risk is surely larger than with bred animals, because humans took up animal products in the course of his life as food. The question arises here whether the risk is larger for the transmission of prions by intake of food than by the implantation of human bone. These questions each patient must answer itself and this depends on its individual food intake. Resumee In summary it can be said that the guideline for the processing of bone reconstruction materials on the legal part is so clearly defined that a disease transmission can be almost excluded. Outside of the Federal Republic of Germany here partially very simple national laws are valid, so that it will be advised against a transplantation (for example GUS states and third world countries). Self-bone is the safest kind of the transplantation. Here the bone is taken either out of the lower jaw, upper jaw or out of the own hip. The points of usage heal completely usually without any complication. |
