Surface modification using the biomimetic method in alumina-zirconia porous ceramics obtained by the replica method
(Wiley-Blackwell, 2018-10-01)
The modification of biomaterials approved by the Food and Drug Administration could be an alternative to reduce the period of use in humans. Porous bioceramics are widely used as support structures for bone formation and ...
Durability of feldspathic veneering ceramic on glass-infiltrated alumina ceramics after long-term thermocycling.
(2010-07-01)
This study compared the bond strength durability of a feldspathic veneering ceramic to glass-infiltrated reinforced ceramics in dry and aged conditions. Disc shaped (thickness: 4 mm, diameter: 4 mm) of glass-infiltrated ...
