A dental implant from the University of Leuven fights infection with its built-in reservoir of antimicrobial drugs.
One of the main risks of dental implants are the biofilms that can form after insertion and lead to infections. To help reduce the risk of these films forming, the new bacteria-fighting implant is made of a porous material and equipped with a reservoir that can be accessed through a cover screw. After the reservoir has been filled with liquid drugs and the implant installed, the drugs will slow disperse to the surface of the implant, preventing infection where the screw meets the bone. By the time all the liquid has been dispersed, the implant will have been safely integrated into the surrounding tissue.
