ABSTRACT
PURPOSE:
This study compared the effect of three intraoral repair systems on the bond strength between composite resin and zirconia core. MATERIALS ANDMETHODS:
Thirty zirconia specimens were divided into three groups according to the repairmethod:
Group I- CoJet(TM) Repair System (3M ESPE) [chairside silica coating with 30 microm SiO2 + silanization + adhesive]; Group II- Ceramic Repair System (Ivoclar Vivadent) [etching with 37% phosphoric acid + Zirconia primer + adhesive]; Group III- Signum Zirconia Bond (Heraus) [Signum Zirconia Bond I + Signum Zirconia Bond II]. Composite resin was polymerized on each conditioned specimen. The shear bond strength was tested using a universal testing machine, and fracture sites were examined with FE-SEM. Surface morphology and wettability after surface treatments were examined additionally. The data of bond strengths were statistically analyzed with one-way ANOVA and Tamhane post hoc test (alpha=.05).RESULTS:
Increased surface roughness and the highest wettability value were observed in the CoJet sand treated specimens. The specimens treated with 37% phosphoric acid and Signum Zirconia Bond I did not show any improvement of surface irregularity, and the lowest wettability value were found in 37% phosphoric acid treated specimens. There was no significant difference in the bond strengths between Group I (7.80 +/- 0.76 MPa) and III (8.98 +/- 1.39 MPa). Group II (3.21 +/- 0.78 MPa) showed a significant difference from other groups (P<.05).CONCLUSION:
The use of Intraoral silica coating system and the application of Signum Zirconia Bond are effective for increasing the bond strength of composite resin to zirconia.
