DD Bio Z

Product Overview

Dental zirconium oxide in all its facets, different translucencies and strengths is always a high-performance ceramic. Even the term of high-performance ceramic describes the opposite of a "dusty" classic.

In 2010 the first DD Bio Z blanks from our own production in Spenge (OWL) came off the production line. On the occasion of the 10th anniversary of this product line one can therefore perhaps speak of an innovation classic. The proven 3Y TZP-A material type, in which 3mol% yttrium oxide (Y₂O₃) and a small addition of aluminium oxide (0.25 wt% Al₂O₃) provide a high-strength, tetragonal microstructure, has not lost its popularity over time.

Despite the trend towards monolithic restorations and increased translucency in zirconium oxide, our production volume of the opaque DD Bio Z has increased steadily over the years. A concept with a product life of more than 10 years in the digital age has to distinguish something special.

Due to the long lasting success and still increasing usage figures we conclude that every ZrO₂- type has its right to exist. Working with a material mix that is adapted to the individual dental technique and laboratory positioning can make a lot of sense.

DD Bio Z not only qualify the best mechanical properties in the product group, but also the fact that a material with high opacity can be of aesthetic benefit. This insight has also been confirmed in the exchange with Andreas Nolte (enamelum et dentinum, Münster), who developed our color and texture system DD contrast® - a system developed for the efficient and aesthetic individualization of monolithic restorations. The interaction of the high translucency of the DD cubeX²® and DD cube ONE® zirconium oxides with the colors and textures of DD contrast® defines a new aesthetic of veneer-free restorations.

For full veneers Andreas Nolte likes to use the higher opacity and optical density of materials such as DD Bio Z as a framework base. Andreas Nolte imparts his knowledge of natural and authentic layering in courses and workshops in his dentinum et enamelum laboratory in the beautiful city of Münster. With his philosophy on anterior aesthetics, he creates masterpieces of craftsmanship that have made a lasting impression on us. DD Bio Z is the ideal material for implant-prosthetic restorations for hybrid abutments on Ti-adhesive bases.

Color Technology

Mono Additive Technology - DD Bio Z color 500 bis 2000

Since the product launch in 2010 we have been producing DD Bio Z in 5 universal colors. The color technology used is described as "Mono Additive Technology". The color is created by adding only one additive; in this case iron oxide (Fe₂O₃), which allows colors to be adjusted in the spectrum from light yellowish to brown-reddish. The type numbers from 500 - 2000 describe the proportion Fe₂O₃ in ppm (parts per million) and thus the intensity of the color.

Multi Additive Technology - DD Bio Z color according to VITA colors

DD Bio Z now in 8 colors according to VITA classical A1 to D4® - produced in the Multi Additive Process.

In order to do justice to the colors of the VITA classical A1-D4® scale of Vita Zahnfabrik, we produce the new DD Bio Z shades using the Multi Additive process - a mixing concept developed by us which is already used for the other DD variations. A raw material cocktail consisting of three different additives in different concentrations makes it possible to set the colors more vivid and nuanced.

The crowns show from left to right the color effect of the individual additives, used in pure form. By mixing the elements the colors can be adjusted according to the VITA classical definition:

• A1 • A2 • A3 • A3,5 • A4 reddish-brownish
• B1 • B2 • B3 • B4 reddish-yellowish
• C1 • C2 • C3 • C4 greyish
• D2 • D3 • D4 reddish-grey

Indications

DD Bio Z: The recommendation for all indications requiring maximum strength. The higher opacity is ideal for laminating metal abutments (hybrid crown) or as an aesthetic basis for full veneers. This is why DD Bio Z is a classic - THE LASTING.
