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 .
The effect of surface treatment on the adhesion of resin cements to Y-TZP.
The purpose of the study was to evaluate the shear bond strengths ( SBS ) of two resin cements to intaglio surfaces of zirconia from two manufacturers after three surface treatment methods . Forty zirconia specimens from one manufacturer ( Lava , 3 M ESPE ) and 40 zirconia specimens from another manufacturer ( Cercon , Dentsply ) , each with system-specific intaglio surfaces , were r and omly divided into four treatment groups ( 20 sample s per group , 10 for each manufacturer ) : no treatment ( No_T ) , s and blasting with 50microm Al2O3 ( S_50 ) , s and blasting with 110 microm al2O3 ( S_110 ) , and Rocatec silica coating and silanization ( ESPE-Sil , 3 M ESPE ) ( Roc ) . A 5-mm metal ring was fixed upon the zirconia and was filled with one of two different resin composite cements ( RelyX Unicem , 3 M ESPE and Panavia F 2.0 , Kuraray ) . Sample s were stored in distilled water at 37 degrees C for 7 days ; SBS was evaluated using a universal testing machine . Values were calculated in MPa and the data were analyzed by ANOVA and Tukey HSD test ( P < .05 ) . In the Lava specimens , the three surface treatment methods tested did not increase the bond strength of Panavia compared to the control group ( P = .195 ) ; using RelyX Unicem , S_50 and Roc , mean SBS values were significantly higher than values for No_T ( S50 P = .0048 ; Roc P < .001 ) . For Lava surfaces treated with Rocatec , there was a statistically significant difference between the two luting cements used ( Unicem 11.39 + /- 2.19 ; Panavia 8.56 + /- 1.17 ; P = .002 ) . Regarding the Cercon specimens , there was a significant difference between the Unicem and the Panavia control groups ( No_T Unicem 1.48 + /- 1.19 , No_T Panavia 4.60 + /- 2.75 , P = .004 ) . In conclusion , all surface treatments increased the bond strength of RelyX Unicem resin cement to both zirconia substrates . No statistically significant changes were found using Panavia on Lava . S and blasting with 110 microm Al2O3 provided the highest bond strength for Panavia on Cercon
