In vitro testing shows good performance of Procera zirconia abutments in terms of fracture load compared to other zirconia abutments.
Bending moments of both Replace Select two-piece internal tri-channel connection and Brånemark System Mk III external connection were similar to Bone Level one-piece (Straumann) and StandardPlus two-piece internal connections (Straumann), and furthermore they significantly outperformed Osseospeed (AstraTech) one-piece internal connection (P<0.05). As expected, the control-restored titanium abutment exhibited higher bending moments as compared with any type of restored zirconia abutments.
