Fracture Resistance of Yttria‐Stabilized Zirconia Dental Implant Abutments [PDF]

Journal of Prosthodontics, 2008
Abstract Purpose: An in vitro study was performed to assess the effect of different degrees of clinical reduction of zirconia abutments on the failure load of clinical assemblies. Materials and Methods: Zirconia abutments (Y‐TZP Ceramic Abutment, Astra Tech) were prepared with 0, 0.5, or 1 mm of external axial reduction starting 1 mm above the height ...
