Porous structures help boost integration of host tissue with implants

Results published in FASEB (the journal of the Federation of American Societies for Experimental Biology) by researchers at Columbia University, including Jeremy Mao of the Columbia College of Dental Medicine, demonstrate a novel way of using porous structures as a drug-delivery vehicle that can help boost the integration of host tissue with surgically implanted titanium.
