Researchers Develop Surface Treatment to Reduce Infection

Researchers at Aalto University are developing a method of analyzing surface treatment processes for orthopaedic and dental implants to reduce the risk of infection. By adding beta-tricalcium phosphate to typical biomaterial coatings such as hydroxyapatite or bioactive glass, the team has reduced stresses that may cause premature cracking and removal of the coating layer. These stresses can lead to the development of unsuitable compounds and increase the risk of infection. Research shows that ten to 15 percent of post-implant complications are caused by bacterial infections.
