PHASE- AND SEDIMENTATION-STABLE, PLASTICALLY DEFORMABLE PREPARATION WITH INTRINSIC PORE FORMING, INTENDED FOR EXAMPLE FOR FILLING BONE DEFECTS OR FOR USE AS BONE SUBSTITUTE MATERIAL, AND METHOD OF PRODUCING IT

摘要

The invention relates to a phase-stable and sedimentation-stable, plastically deformable preparation with intrinsic pore forming, which can be used, for example, for filling bone defects and for augmentation, and also to a method of producing it. The object of the invention, namely to provide a phase-stable and sedimentation-stable, plastically deformable implant material with intrinsic pore forming that can be realized at low cost and inconvenience and can be introduced by injection into a bone defect or alternatively, as a kneadable compound, can be applied/adapted into a bone defect, is achieved by virtue of a plastically deformable preparation for bone construction/replacement, based on ceramic suspensions, comprising a particulate, porous component of low water-solubility and at least one liquid, wax-like or gel-like component in solution in water or alcohol, the component of low water-solubility amounting to 60-98% by weight and the component in solution in water or alcohol amounting to 1-30% by weight, the particles of the particulate component having a diameter in a size range which is substantially greater than one phagocytable particle and smaller than the passage diameter of standard injection cannulas, and the fraction of the dissolved component in the water or alcohol amounting to 0.1%-3% by weight.
