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.
Second, the simplicity of using zinc phosphate cements, their ease of removal from marginal regions after setting, and the ease with which a zinc phosphate cemented crown can be removed if remake is needed, are beneficial clinical advantages that cannot be neglected.
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.
These ZrO 2 copings, like the Procera copings, cannot be etched because of the acid resistance of ZrO 2 . Although a resin-based cement such as Panavia is the recommended luting agent for Denzir at the present time, there is an interest in determining whether zinc phosphate and glass ionomer cements are acceptable alternatives.
