The biological reaction to some zirconia ceramics, mainly tetragonal zirconia polycrystals (3Y-TZP), has been reported in the literature. Various forms have been used including bulk materials, ...

In vivo studies have shown that chipping of the veneering porcelain is the major failure mode for zirconia dental restorations. 27,28 The TMT during aging could be a contributory factor for chipping.

NanoZirconia (ZrO 2 nanoparticles) has been used as a catalyst in various organic reactions, in photocatalytic and piezoelectric applications, as well as dental and optical coatings. It exists in ...

Although the optically transparent single-crystal ZrO 2 form has a very high thermal shock resistance, it also has poor fracture toughness and strength. Zirconia is well-known among ceramics for being ...

Teeth become more translucent as we age, but is the same true for uncolored zirconia ceramic restorations? Researchers put four of these restorative materials through an aging process to find out if ...
