Because of the acid resistance of Al 2 O 3 , and the knowledge that existed when the first Procera crowns were introduced at the end of the 80 thand the early 90 th, the first Procera crowns were cemented with zinc phosphate and glass ionomer cements [ 11 ] . These cements were used because it was believed that the high fracture toughness of Al 2 O 3 copings, a property superior to that of traditional dental ceramics, would result in strong ceramic crowns.
In addition, by using zinc phosphate and glass ionomer cements rather then resins, Procera profited from other advantages too.
If the retention of Denzir is as good as that of Procera, one would expect that Denzir crowns will provide as good or even better clinical results than those reported with zinc phosphate or glass ionomer cemented Procera crowns [ 11 13 ] .

However, the published results [ 13 ] suggest that the use of zinc phosphate and/or glass ionomer cement is not a major factor considered contributing to permanent failures of Procera crowns.
At the time the first ceramic Procera crowns were introduced, ceramic restorations were often cemented with zinc phosphate or glass ionomer cements, despite the fact that research had started to show the advantages with resin bonded ceramic restorations [ 10 ] . Resin bonding was achieved by first etching the ceramic surface with hydrofluoric acid and treating the ceramic surface with a silane [ 10 ] . However, acid etching did not work on the hydrofluoric acid resistant Al 2 O 3 copings.
