How can you use “cements” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
Today, we know the outcome of cementing Procera crowns with zinc phosphate and glass ionomer cements [ 11 13 ] . Of the placed 87 crowns, 79 had been cemented with zinc phosphate cement and the remaining 8 crowns with glass ionomer.
Such an explanation can be related to the setting reaction of zinc phosphate cements.
In addition, clinical experience evolving at that time suggested that the fracture rate of ceramic restorations decreased if they were resin bonded rather than cemented with traditional zinc phosphate or glass ionomer cements [ 5 ] . However, because of high equipment cost and a not yet optimised technology, the Cerec system did not capture a big market share.
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.
