Abstract:

Objective

To evaluate the shear bond strength (SBS) between resin cement and zirconia under different experimental conditions.

Methods

In present study, six cubic zirconia specimens with a side length of 2 cm were cut by computer aided design/computer aided manufacturing (CAD/CAM) equipment and sintered afterwards. According to different experimental conditions, eight kinds of dual-curing resin cements were divided into 13 groups, such as: (1) Monobond N + Multilink N (MMN) ; (2) Ivoclean + Monobond N + Multilink (IMM) ; (3) Ivoclean + Monobond N + Multilink N [no sandblasting, IMM (ns) ]; (4) Tetric N-Bond Universal + Multilink Speed (TUM) ; (5) Multilink Speed (MLS) ; (6) Z-Prime Plus + TheraCem (ZPT) ; (7) Z-Prime Plus + Duo-Link (ZPD) ; (8) Single Bond Universal + RelyX U200 (SRU) ; (9) RelyX U200 (RXU) ; (10) Single Bond Universal + RelyX Ultimate Clicker (SRU) ; (11) OptiBond Versa + Kerr NX3 (OVK) ; (12) Clearfil Universal Bond + Clearfil SAC (CUS) ; (13) Clearfil SAC (SAC) . Each resin cement was injected into a transparent mould after self-mixing, and put onto the zirconia surface without pressure when finally being light-cured (n = 20) . The SBS test of the all specimens was performed after 24 hours of 37 ℃ water storage, and the results were statistically analyzed by One-Way ANOVA, SPSS 19.0 software (P<0.05) . The fracture mode on zirconia surface was observed by electron stereoscopic microscope.

Results

The bond strength (MPa) of resin cements in a descending order was: OVK (27.51 ± 3.65) >IMM (27.28 ± 3.79) >SRC (26.77 ± 3.62) > CUS (25.36 ± 3.10) >TUM (25.22 ± 4.88) >ZPD (23.96 ± 6.25) >MLS (23.13 ± 2.74) > MMN (23.07 ± 3.71) >SAC (22.20 ± 3.59) >IMM (ns) (21.99 ± 3.50) >SRU (19.19 ± 2.27) >ZPT (18.62 ± 2.08) >U200 (15.04 ± 4.02) .

Conclusions

(1) The SBS of resin cements was material-dependent. (2) The SBS of resin cement could be improved by sandblasting, using a special cleaning agent or universal adhesive as a primer on zirconia surface.
