Dr. Noumbissi was invited to speak at the 28th annual meeting of the International Academy of Oral Medicine and Toxicology in Minneapolis. The topics presented were Zirconia  as a dental implant material. Zirconia is the ceramic state of the metal zirconium which has been used for over twenty years in orthopedics. For the last decade it has also been used as a metal-free dental implant material.  Unfortunately there is a lot of misunderstanding and misinformation both among dentists and the public as to the  viability and predictability of zirconia as an oral and maxillofacial implantable material.  The second presentation was focused on the clinical applications of zirconia dental implants, cases presented ranged from single tooth replacement to full arches metal-free rehabilitation.
