BioactIF OSTEOTRANS

Redefine biodegradation!

BioactIF OSTEOTRANS is the name for the new generation of bioactive and bioresorbable interference screws from Richard Wolf. The unique Osteotrans composite material made of Poly-L-Lactide (PLLA) and unsintered Hydroxylapatite (uHA) demonstrates an osteoconductive effect in bones. Trabecular structures grow into the surface of the implant from the surrounding bone within a short time frame.

The distribution of uHA particles generated uniformly by a special manufacturing process also creates a permanent buffer of the lactic acid produced in the course of degradation of the PLLA components and hence prevents inflammatory reactions in bones and tissue, as well as encapsulation of the implant.

The mechanical characteristics generated in the course of the special manufacturing method for the material are comparable with the properties of the surrounding bone. The transfer of forces from the surrounding bone to the implant is thereby ensured. This is a key prerequisite for activating the osteoblasts. Complete bone reconstruction can hence be achieved for this area. The implant can easily be seen in X-ray visualization.
