Innovations in bonding to zirconia-based materials
Aboushelib MN et al. - The combination of selective infiltration etching with experimental zirconia primers significantly improved the MTBS values compared to the ’as-sintered’ surface using the same primers which demonstrated spontaneous failure and very low bond strength values. SEM analysis revealed that selective infiltration etching surface treatment resulted in a nano-retentive surface where the zirconia primers were able to penetrate and interlock which explained the higher MTBS values observed for the treated specimens.
