Abstract
Purpose: To investigate the effect of cleaning procedures (ultrasonic, autoclaving) and aging methods (24 hours, 90 days, and thermocycling) on the shear bond strength (SBS) between alumina-particle air-abraded titanium (Ti) and zirconia (Zr; 3Y-, 4Y-, and 5Y-TZP) specimens luted with phosphate monomer-containing adhesive systems and resin-based composite.
Materials and methods: Lab-side-fabricated test specimens were prepared by bonding different Zr plates to Ti cylinders using a resin-based composite. The cleaning procedures included ultrasonic cleaning and purging (UUP) or two stages of purging and autoclaving (PPA). The specimens were then aged for 24 hours, 90 days, or had to endure thermocycling.
Results: Autoclaving significantly improved SBS (F [27,231] = 17.265, P < .001) compared to no cleaning and three-stage disinfection.
Conclusions: No differences were identified with regard to Zr or aging methods. Bond strength initially benefits from autoclaving but continuously approaches the comparative values over longer periods.
