In vitro performance of Nobel Biocare Replace and Brånemark zirconia abutments show strength testing results equal or superior to other zirconia abutments after aging.¹

Zirconia strength testing results

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.
