【 摘 要 】

Metallic ion release has raised concerns for the utilization of titanium and titanium alloys in implant dentistry. As an alternative, yttriastabilized tetragonal zirconia (Y-TZP) has been considered the material of choice due to its favorable biological and mechanical properties. Zirconia has been shown both in vitro and in vivo experiments to exhibit desirable osseointegration, cell metabolism, and soft tissue response. According to the mechanical testing of unaged Y-TZP onepiece implants, catastrophic failure of ceramic implants in anterior esthetic regions is unlikely. The utilization of a one-piece Y-TZP implant might be an option to fulfill the esthetic and mechanical needs in oral implant treatments when esthetics is the major concern.
