Properties
CeraBlock™ Zirconia by CeraSys

Zirconia has proven itself as a bio-compatible material in
implant dental surgery for many years. CeraBlock™
Zirconia demonstrates no measurable solubility or water
absorption and shows a high initial stability and excellent
long term stability. Therefore, the strength of this
material is maintained, even after a long periods in situ.
CeraBlock™ Zirconia has no allergenic potential and is
very bio-compatible.
CeraBlock™ Zirconia withstands many times the load
level occurring in the mouth (loads measured for
anterior teeth up to 400 N, posterior teeth up to 600 N,
for bruxism even up to 800 N). Its strength is
considerably higher than other all-ceramic materials.
Unlike infiltrated or glass ceramics, it is particularly
suitable for posterior bridge frameworks and for long
spans.
