Evonik has partnered with Samaplast, a Swiss specialist in high-performance polymer injection molding, to produce a prototype of a
spinal implant based on bone conductive polyetheretherketone (PEEK) through injection molding.
This result combines the expertise of both companies and validates the excellent processability
of the new bone conduction high-performance polymer ^VESTAKEEP@Fusion.

Because during the injection molding process, a thin polymer film usually forms on the surface of the implant, enveloping the bioactive ingredient and preventing osteoblasts from attaching to the
implant.
So far, injection molding processes have not been able to produce implants
containing polymer compounds with bioactive ingredients.
Unlike VESTAKEEP@Fusion, thanks to the special configuration of functional biphasic calcium phosphate (BCP) particles and their uniform distribution in VESTAKEEP^@i4G, BCP remains on the surface of the injection molded part after injection, thus promoting full integration
of bone and implant.

One of the development goals of VESTAKEEP^@Fusion is to make it suitable for a wide range of production processes
.
The product is available as semi-finished products such as pellets and profiles and can be machined, thermoformed, extruded or even injection molded
.
