Bioceramic Coated Implants

Description:

Background:

Medical implants are vital in many lives because they replace missing body parts and the functions that come along with them. To avoid rejection by the host, the implants must be composed or coated in bioceramic materials.  Many of the current methods to achieve this have several disadvantages, such as, micro-cracks, phase changes due to high temperature exposure, and non-uniformity in the coating density. Researchers at the University of Nevada, Reno have developed an improved method to create a nanoporous metal oxide surface for stronger bioceramic-coated apparatuses.

 

Description:

Our researchers have created a method for forming a bioceramic-coated apparatus which uses a metal substrate with a nanoporous metal oxide surface to anchor the bioceramic coating.  This technology can be applied to bone repairs, tooth replacements, bone-integrated electronic devices, prosthetic limbs, and many other apparatuses designed as surgical implants.  Our bioceramic coated implants will benefit the medical industry significantly since it can be used in a wide variety of applications, and it has an improved tensile strength, durability and adhesion between the coating and the substrate.

 

Advantages:

  • Our bioceramic coated implants can be used in a wide array of application such as hip replacements, prosthetic limbs, stents, dental fillings, respirators, etc.
  • Our in vivo testing demonstrates double the durability compared to current methods.
  • Our implants have an increased tensile strength because of the nanopores.
  • Our method creates a nanoporous surface that helps improve the adhesion between the bioceramic coatings and substrates.
