Are we able to increase the retention for zirconia restorations without bonding?  The answer is yes.  This video will document my last ten years of keeping zirconia restorations in place using glass ionomer cement.  Clinically, I want to consider ways of removing crowns and bridges if and when they need upgrades due to subgingival caries.  We all know how difficult it is to remove an e.max bonded full crown.  Just think of how difficult it will be to remove a bonded zirconia crown if and when it needs removal.  An Erbium-Yag laser will help, but not everyone has laser assistance for removing bonded restorations.
