Oxford Performance Materials and Sintx Technologies develop orthopedic coating


Oxford Performance Materials and Sintx Technologies have announced the development of a new class of coatings that can be used for orthopedic implants. 

The coatings are aimed at helping overcome the limitations of traditional metallic implants, according to an Aug. 23 press release. 

The coating can be applied to biomedical metallic substrates, using polymer biomaterials that already have FDA clearance for human implantation. 

The new coating does not rely on the presence of antibiotics or antibacterial materials to discourage bacterial adhesion. 

"The PEKK-silicon nitride composite coating is very exciting because it adds to the proven attributes of metal implants by imparting bacterial resistance, speeding up bone ingrowth, and reducing metal ion exposure in the body. In the next phase of our collaboration with OPM, we will optimize the coating process, apply the coating to complex device surfaces, conduct rigorous chemical and biological evaluations with clinically relevant bacterial strains and bone cells, and undertake standardized testing protocols toward securing regulatory clearances and product claims," Sintx CEO Sonny Bal said in the release.
