Abstract:

BACKGROUND: Repair materials and abutment bonding technology have always been the research focus of prosthodontics, particularly surface treatment process.
OBJECTIVE: To observe the effect of six different surface treatments on Ceramage polymer-ceramic bond strength and to find the proper surface treatment method.
METHODS: Eighty polymer-ceramic specimens were randomly divided into 8 groups, respectively, using the following 8 ways: A: No treatment; B: Sandblasting; C: Etching; D: Silane coupling agent; E: Sandblasting + etching; F: Blasting + silane coupling agent; G: Etching + silane coupling agent; H: Sandblasting + etching + silane coupling agent bonded with Panavia- F resin cement. After storage at 37 ℃ water for 24 hours, the specimens were subjected to a shear bond strength test. Surface morphology of polymer-ceramic was observed using scanning electron microscopy.
RESULTS AND CONCLUSION: Shear strength values of 8 experimental group (MPa) from the highest to the lowest were as follows: H group (31.12±2.81), E group (27.62±1.70), G group (27.31±2.18), F group (26.91±1.97), B group (24.23±2.03), D group (23.50±2.19), C group (17.61±2.14), A group (8.13±0.63). There was no significant difference between B and D groups as well as among E, F and G groups (P > 0.05); the remaining groups were statistically significant between groups (P < 0.05). Seven kinds of surface treatment methods have increased the bond strength; Sandblasting group and Coupling group was significant higher than Etching groups; Sandblasting, etching in combination with silane coupling agent group showed the highest bond strength, which was the most proper surface treatment method for Ceramage polymer-ceramic bonding.
