An as-produced surface of oxide ceramic needs to be surface treated to achieve durable bond strength .
Abrasive surface treatment and /or silica-coating treatment with the use of primer treatment can provide sufficient bond strength for bonding oxide ceramics .
The following aims were set for this systematic literature review : ( a ) to make an inventory of existing methods to achieve bondable surfaces on oxide ceramics and ( b ) to evaluate which methods might provide sufficient bond strength .
Effect of surface treatments and aging in water on bond strength to zirconia.
The current study evaluated the effects of various pretreatments and aging in water on the bond strength to hot isostatic pressed yttrium-oxide partially stabilized zirconia . Sixty zirconia ceramic specimens ( Denzir ) were r and omly divided into three groups of 20 . One group of specimens ( n=10 ) was then bonded to each other using a resin composite cement ( RelyX Unicem ) , the second group ( n=10 ) was bonded with RelyX Unicem and a metal primer ( Metal Primer II ) , while the third group ( n=10 ) was bonded with RelyX Unicem and a ceramic primer ( Ceramic Primer ) . The specimens were then subjected to shear force before and after s and blasting and before and after aging in water for 180 days . Before aging , no significant differences ( p > 0.05 ) were seen within the different groups , either before or after s and blasting . S and blasting and pretreatment with the metal ( p < 0.01 ) or ceramic ( p < 0.001 ) primers significantly improved the bond strength compared to that of the non-treated specimens . After aging , the bond strength of the s and blasted specimens with metal primer was significantly higher than that of the s and -blasted specimens with ceramic primer ( p < 0.01 ) and the specimens with no primer ( p < 0.001 ) . For the specimens that were s and blasted and pretreated with the metal primer , the bond strength was not significantly affected after aging ( p > 0.05 ) , whereas , for those specimens with the ceramic primer ( p < 0.001 ) and no primer ( p < 0.05 ) , the bond strength significantly decreased . Thus , air abrasion and pretreatment with a metal primer seems to be an appropriate method for improving bond strength
