Bioactive Film Improves How Implants Bond with Bone

Researchers from several universities have developed a technique for coating polymer implants with a bioactive film that significantly increases bonding between the implant and surrounding bone. The polymer, polyether ether ketone, also known as PEEK, has properties that make it appealing for use in implants, but it doesn't bond well with bone. The research team tested several methods to coat the polymer, including using a thin film of yttria-stabilized zirconia followed by a coating of hydroxyapatite. The team then heated the coating with microwaves, which makes the crystalline hydroxyapatite structure more stable in the body and more capable of bonding with bone.
