Bloomden Bioceamics provides super translucent solid zirconia used for full zirconia crowns or copings in the aesthetic zone, It is a fully-contoured dental restoration with no porcelain overlay.

 

These solid zirconia blocks are formed under pressure from nano purity zirconium oxide powder stabilized with yttria, plus additional unique additives for bonding and translucency. Processed by cold isostatic pressing and precise sintering controls, the blocks are guaranteed to have a homogenous density and shrinkage distribution and extremely constant material characteristics.

 

Solid zirconia has quickly become the preferred replacement for full-cast and porcelain to metal restorations in the posterior.

FAQ

Q: Are there differences among zirconia ceramics?

 

A: Differences among zirconia ceramics can occur with the level of purity of zirconia; grain size, trace elements and stabilizing compounds; and consistency of formulation. Differences can exist in shrinkage from batch to batch because of differences in the coefficient of thermal expansion (CTE).

 

 

Q: Zirconia substructures have high flexural strength, 900-1200 MPa, but what is the flexural strength of the zirconia/porcelain system?

 

A: Flexural strength is typically performed on a three-point bend specimen and is a function of relative thickness of the zirconia and overlaid ceramic, but it would not exceed the flexural strength of the zirconia.

 

Q: Does zirconia ceramic degrade in strength intraorally in 5-10 years?

 

A: Yes, all-ceramic materials degrade in strength over time - some more than others. Zirconia ceramic  has an initial flexural strength of over 1200 MPa, so even if it degrades 5-10% or more, it is still significantly stronger than other ceramics.

 

 

Q: Is the fit of crowns and bridges based on zirconia copings as good as that of PFM crowns and bridges?

 

A: Yes, the marginal fit of crowns and bridges fabricated from zirconia copings can be as good or better than PFM crowns and bridges.

 

 

 

Q: Is the fit of a zirconia coping important since the zirconia ceramic is so strong?

 

A: The thicker the cement the weaker the all-ceramic restoration. Cements are not as rigid as zirconia ceramic, so a thicker cement layer will cause more flexural deformation of a ceramic core, increasing the potential for fracture.

 

 

Q: Is it ok to grind on a zirconia coping without water spray?

 

A: Water spray is necessary when grinding on a zirconia ceramic coping. The white light or hot spot you see between a diamond and a zirconia ceramic has been measured at 1500 ºC. If the temperature of zirconia ceramic rises above 1000 ºC, a phase change can occur that will induce cracking and surface defects, lowering the strength of the coping.
