Evaluation of zirconia/resin bond strength and interface quality using a new technique.

摘要: PURPOSE Selective infiltration etching is a newly developed surface treatment used to modify the of zirconiabased materials, rendering it ready for bonding with resin cements. The aim this study was evaluate zirconia/resin bond strength and durability using new technique. MATERIALS AND METHODS Zirconia disks received one following treatments: selective or airborne-particle abrasion 50-μm aluminum oxide particles, while as-sintered surfaces served as control. zirconia were bonded pre-aged composite light-polymerized adhesive (Panavia F 2.0). evaluated microtensile test (MTBS) repeated after each intervals accelerated artificial aging: thermocycling (10,000 cycles between 5°C 55°C), 4 weeks, 26 52 104 weeks water storage (37°C ). A measures ANOVA Bonferroni post-hoc tests analyze data (n = 18, α 0.05). RESULTS There significant differences in MTBS values three groups at (p < 0.001). After 2 years aging, all specimens control group demonstrated spontaneous failure, reduction particle-abraded observed (21.3 MPa). etched relatively stable (44.1 MPa) completion aging. CONCLUSION Within limitations study, micromechanical retention adhesion promoters are prerequisites establishing strong durable zirconia-based materials.
