| titleOfInvention | Inorganic resorbable bone substitute material and production method |
| abstract | The invention relates to an inorganic resorbable bone substitute material based on calcium phosphates and to a method for producing the same. The material is characterized in that it comprises a loose crystal structure, i.e. the crystallites are not tightly connected as in a solid body (ceramic), but they are interconnected via only a few molecular groups. The volume which is occupied by collagen in natural bone is provided in the material as interconnecting pores in the nanometer range. A second pore size, also interconnecting and in the range of a few micrometers, permits collagen fibers to grow inside during tissue formation. These fibers are nucleators for the inserting biomineralization (formation of the endogenous biological apatite). The material contains a third interconnecting pore category which is modeled on the spongiosa and ranges from approximately 100 µm to 1000 µm. The invention also relates to a method for producing such a material which is characterized in that a highly viscous suspension of a sol of one or more oxides of the elements X (X = Al, Ca, Mg, P, Si, Ti, Zr) that is mixed with a crystalline powder is forced through a nozzle or a nozzle system and subsequently formed into any desired shape. An open porous structure with a size corresponding to that of the filament diameters results by packing the fibers from the highly viscous suspension. |
