Optical and mechanical properties of zirconia ceramics with nano-sized grains for dental application


Personnes à contacter par le candidat


Zirconia and lithium disilicate glass-ceramics are currently the most popular alternatives for monolithic restorations, since they offer good balance between strength, translucency and long-term properties in the buccal environment. High strength and translucency are generally not coincident in one restorative material and there is still a continuous development for a better balance between these two properties. In particular, there is a trend today to develop highly translucent yttria-doped zirconia ceramics by playing with the amount of yttrium and/or decreasing the grain size down to the nanoscale (i.e. below 100 nm).
