Excellent Aesthetics

It is important to reproduce the translucency of the natural tooth, as it provides an enchanted natural appearance of the prosthetics. Translucency is the substance property that allows the passage of light and its dispersion, and then the objects will not be seen clearly through the material. This property could be defined as a state between transparency and complete opacity. Translucency can be regulated by controlling the absorption, reflection, and transmission of light through the material. The translucency is higher when the reluctance is low and the transmission is high.

Strength as a trend

Previously at very initial phase, the advancement in aesthetics was limited to the lower strength zirconia, such circumstance that couldn't enable technicians to use for bridges over 3 crowns. However Bloomden 3D Pro multilayer zirconia is unlike any other zirconia, it can exhibit a strength range from 650MPa to 1200MPa which can cover posteriors and anteriors for both crowns and bridges including implant restorations. The high strength layer (dentin layer) of 3D Pro is developed to avoid any areas of weakness when contacting food, or human's natural teeth.

Monoclinic resistance

3D Pro multilayer zirconia's unique hydrolysis microstructure and chemical formulation by the hydrothermal treatment also resist degradation of aging which the cubic shifted to monoclinic state that can be observed in zirconia structure.

High speed sintering cycle

one of 3D Pro multilayer zirconia's excellent attributes is the fast sintering cycle which can ensure the strength, translucency and aging resistance simultaneously. The high-productivity sintering cycle allows for “inside furnace” time in 45 minutes.

Low Wear Rate

The average crystalline size of less than 0.5 μm and the Hydrolyzed powder properties are organized inside 3D Pro multilayer zirconia which enable 3D Pro multilayer zirconia to be long-term enamel wear behavior closed to the natural human teeth after several times of lab-test. The study revealed that the aged zirconia and polished zirconia both have identical roughness and less wear of opposing enamel.

Below is Bloomzir® 3D Pro Multilayer case:

Bloomzir® 3D Pro Multilayer combined the concept of nature and beauty, with smooth color gradation, very matching VITA® shades as below full arch case shows. Meanwhile the Bloomzir® 3D Pro Multilayer phisical states can be kept well with our R&D technology to ensure a long term aesthetic apprearance.

Zirconia physically has monoclinic, tetragonal and cubic states as below:

 

the tetragonal state could be transformed to monoclinic during the sintering and volume reduction could be occurred inside of zirconia, this may cause the strength loss and high risk of crack and ageing.

 

Bloomzir® 3D Pro Multilayer is developed to avoid the shifting from tetragonal to monoclinic state that ensuring no crack and ageing risks, and Bloomden technicians already experienced many tests to utilize the qualification performance with stablized 50% tetragonal and 50% cubic states which can maintain the strength of zirconia after 1500℃ sintering to be durable full arch, and it's getting more and more popular from many dental lab and dental clinic friends that many cases of full arch of Bloomzir 3D pro zirconia were fabricated.
