Influence of Collagenfleece on bone regeneration.

It can be demonstrated that bone regeneration is stimulated by implantation of Collagenfleece a purified, heterologous collagen preparation. Defects were created in rabbit mandibles which were filled with Collagenfleece on the right side, while the defect on the left side served as a control. The progress in bone regeneration was followed by comparative light and electron microscopic investigations. In contrast to the controls, the defects which were treated with Collagenfleece showed quicker ossification.
