The mismatch in coefficient of thermal expansion (CTE) between the veneered
porcelain and the ceramic core has been primarily identified as the cause of core/veneer chipping
in all-ceramic restorations. This study aimed to evaluate the effect of sodalite infiltration on the
CTE behaviour and bond strength of different all-ceramic prostheses. Materials and Methods: The
experimental groups were synthesised sodalite-infiltrated alumina (IA-SOD) and synthesised
sodalite-infiltrated zirconia-toughened alumina (ZTA) (IZ-SOD), while the control groups were glassinfiltrated alumina (IA-glass) and glass-infiltrated ZTA (IZ-glass). (Copied from article).
