Changes in the flexural strength and surface characteristics of different zones of multilayered translucent zirconia during aging process.

ABSTRACT:

Objectives

This study evaluated the mechanical and surface characteristics of the transition zone of multilayered translucent zirconia (TZ) after aging and analyzed the correlation between the 4-point bending flexural strength (4PBFS) and biaxial flexural strength (BFS) in each zone.

Methods

Traditional (3Y-TZP of LT; L, 4Y-TZP of MT; M) and multilayered TZ (5Y-TZP of MT Multi; T, 3Y/5Y-TZP of Prime; P, 4Y/5Y-TZP of Prime esthetic; E) IPS E.max ZirCAD blocks were used to fabricate 525 disk-shaped and 300 bar-shaped specimens. Specimens were separated into three groups, aged in an autoclave at 134 °C under 0.2 MPa for 0 h, 5 h, and 10 h. The mechanical and surface characteristics of the transition zone in multilayered TZ were analyzed, following statistical analyses (α = 0.05
