“…The existence of a reaction layer at the bonding interface between Ce-TZP/Al2O3 and porcelain could not be ruled out as conclusively as in previous reports which observed TZP/porcelain interface using micro X-ray diffraction (µXRD) 18,19) , energy-dispersive X-ray spectroscopy (EDS) 20,21) , and WDS 15,22) . Due to insufficient resolution in these studies, the interfacial transition layer could only be declared as non-existent with a caveat.…”

The surface of a ceria-stabilized tetragonal zirconia polycrystal (Ce-TZP/Al 2 O 3 ) nanocomposite was sandblasted by alumina particles and veneered with feldspathic porcelain via a conventional condensation method. The part of each specimen containing the interface layer was sliced to ultrathin sections with an argon ion slicer, and these sliced sections were observed using high-resolution transmission electron microscopy (HRTEM). For both interfaces, Ce-TZP/porcelain and Al 2 O 3 /porcelain, no transition layers due to abrupt changes in atomic distributions were observed. Besides, the porcelain layers of both interfaces consisted of homogeneous amorphous phases. These results suggested that both Ce-TZP and Al 2 O 3 could be directly bonded to porcelain by Van der Waals forces arising from the close contact between them.
