Two-piece Zirconia Implants: An Office based Retrospective Study with up to 7 and mean 3 Year Follow-Up

Two-piece, screw-retained zirconia implants showed a high survival rate and stable peri-implant tissue conditions over a period of up to seven years. They represent a promising metal-free alternative to titanium implants. Further prospective long-term studies are needed to validate these results and to better understand potential risk factors.
