Bonding to Zirconia (A Systematic Review)

The aim was set for this systematic review: to analyze the recent techniques of bonding to zirconia. Current literature of in vitro studies regarding bond strength achieved using different surface treatments on zirconia in combination with adhesive cement systems was selected from PubMed and systematically analyzed and completed with reference tracking. The total number of publications included was 557 studies. The surface treatments are divided into two main groups: Surface micro roughness techniques and chemical surface treatment. Conclusion, Fusion sputtering , Selective infiltration etching ,Plasma oxyfluoride, Nano-alumina coating, Application of a tribochemical silica coating, Zirconia & metal primers or Zirconia particle deposition can result in sufficient bond strength for the bonding of oxide ceramics. Resin cements containing esteric organophosphate monomer (MDP) have shown in different studies a higher capacity of adhesion and stability after aging process; this is attributed to the capacity to bind metal oxides such as zirconium oxide (ZrO2).
