The recently introduced dental ceramics
such as luecite, lithium disilicate, lithium disilicate reinforced glass ceramics, alumina and zirconia can be used for the fabrication of multiple unit posterior FDPs due to their better mechanical stability as compared to earlier used ceramics.
It is therefore generally accepted that tests performed in a humid environment and under cyclic loading are needed to provide valuable information on the longterm performance of dental ceramics
Mechanical strength and subcritical crack growth under wet cyclic loading of glass-infiltrated dental ceramics

Lloyd, "Edge toughnes" and material properties related to the machining of dental ceramics
are a huge business, with about 15,000 labs in the United States alone.
Form grinding of dental ceramics
(milling units) changed from a less precise diamond grinding wheel, which required more clinical adjustment, to a more precise 2-bur system in 2006 with a reduced diameter at the tips allowing for a more optimal internal and external detail of the ceramic restoration.
The ten chapters in this collection report new developments in dental ceramics
, the biocompatibility of dental materials, bone and tissue regeneration, and the repair of small cavities in the primary teeth of children.
are the most natural appearing materials available in a range of shades and translucencies to achieve ultimate esthetic results.
A-line Dental ceramics
work in the following areas: Crown and bridge, prosthetics, implants, CAD CAM and smile design.
The future looks good for us as long as we keep up the level of quality and service," says John Proeller, owner of Timmins Dental Ceramics
Part two discusses a wide range of dental polymer composites whilst the final set of chapters in part three look at dental ceramics
Recently zirconia has emerged as a versatile and promising material among dental ceramics
due to its excellent mechanical properties owing to the trans- formation toughening mechanism.
The use of zirconia in dental implant abutment has been introduced because of its high fracture resistance compared to alumina and other dental ceramics
