Stimulation der Regeneration von Knochendefekten durch Einsatz einer Biokeramik und autologer Osteoblastentransplantation

Abstract: It seems that this bioactive ceramic is successful as a bone replacement material and will be suitable as a carrier for osteoinductive substances such as bone morphogenetic proteins.

“…The main differences between these materials are their ability to induce differentiation of cells, their rate of resorption and the possibility to apply rapid prototyping techniques in order to fully control the architecture and the outer design of the scaffold. Ceramics are well known to induce differentiation of potentially osteogenic cells towards the osteogenic lineage [62][63][64][65][66][67] and they are able to bridge large bony defects in human if combined with MPC [68]. Even if it seems to be possible to design a standardized hydroxyapatite ceramic scaffold with the help of rapid prototyping techniques [69], the architecture of a given scaffold (i.e., the size and the interconnectivity of the pores) as well as the mechanical properties can be controlled much…”

“…Testifying of calciumsulfate-bruschit as a new bone substitute material -An investigation in skulls of rats ORIGINAL Einleitung Die Entwicklung von alloplastischen Knochenaufbaumaterialien auf der Basis resorbierbarer knochenähnlicher mineralischer Matrices erscheint versprechend [11,15]. Calcium-phosphatzemente bieten den Vorzug, dass bei ihrer Resorption Calcium-und Phosphationen frei werden, die im Defektbereich für die Synthese von neuem Knochen zur Verfügung stehen, dessen anorganische Grundsubstanz zu fast 70% aus Calciumphosphat besteht [4].…”

“…Die REM-Befunde bestätigen die vorwiegend bindegewebige Regeneration der versorgten Rattenkalottendefekte bis zur 12. Durch Substitution mit Siliziumdioxid sind hochdisperse HA-Matrices mit verbesserter Biodegradierbarkeit herstellbar, die auch bei Defekten kritischer Größe innerhalb von 8 Monaten nahezu vollständig abgebaut werden[11,15].Abb 10: Histomorphometrischer Vergleich der flächenbezogenen Knochenneubildung in histologischen Schnittpräparaten der Versuchs-und Kontrollgruppen (Maximal-, Mittel-und Minimalwerte) Auch die Absenkung des Bruschitanteil auf 25% und die anteilmäßige Erhöhung des leichter löslichen Kalziumphosphatanteils auf 75% vermag dies nicht grundlegend zu ändern.…”

“…Histological and immunohistochemical studies demonstrated its osteoconductive nature and early remodeling in the host tissue. 10,13,14 Animal experiments, using a mini-pig critical-size defect model in alveolar bone, showed high rates of bone formation and nearly complete resorption of the implant within 8 months. 15 …”
