Dental Burs For Zirkonzahn M5 Cad Cam Dental Apron Metal Milling Burs

Product DescriptionDental Burs For Zirkonzahn M5 Cad Cam dental apron metal milling burs

Thriden Industrial Co., LtdTDzirprovides 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.1.

A: We are factory.Q: How long is your delivery time?
A: Generally it is 3-15 days according to our storage.Q: Do you provide samples ? is it free or extra ?A: Yes, we could offer the sample for free charge but do not pay the cost of freight.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 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.

Q: Is preparation design of a zirconia coping important since the zirconia ceramic is so strong?
A: Preparation design of the zirconia coping is very important. The thickness of unsupported porcelain should not exceed 2 mm. The zirconia coping should be as thick as needed to avoid unsupported porcelain
