Concerns

As with all new materials and technology, dental zirconia does have its drawbacks.

Many dentists are hesitant to use zirconia because there are fewer long-term research studies to assess its properties and compare the longevity of the material to gold, porcelain, and lithium disilicate. However, the studies completed thus far all reflect positively on the future of zirconia crowns.

There is also a lack of ability to bond the material to the preps. Though, that might be seen as an advantage by some, since only cement is needed to permanently seat the restoration. The hardness, while certainly considered one of zirconia’s advantages, might be a disadvantage when having to remove or access through them for endodontic treatment.

Chairside adjustments, while usually minimal, must be made safely, using diamond burs at slow speed with copious amounts of water, polishing wheels, and cones specifically designed for use with zirconia.

Do not use carbide burs or diamonds at high-speed for adjustments due to microscopic fractures that can occur from the impact of the burs on the material.

The future of zirconia use in dentistry is unlimited.

Gold and other noble metals used for decades are slowly dying out due to not only prohibitive cost, but also lack of demand by consumers. Zirconia more than fills that gap.

Researchers continually improve the translucency of these restorations, making them legitimate rivals to all-ceramic for beauty and surpassing other dental materials for strength and durability.

Pre shaded zirconia has become popular with dental laboratories due to the time-savings and shade consistency the base shade provides. With pre-shaded zirconia there is no need for laboratory technicians to shade each unit in the green stage, saving production time and freeing them up to produce more units. However, standard pre-shaded zirconia systems require the dental laboratory to stock an inventory of 16 shades, each in a large selection of disc thicknesses to cover all unit shades and sizes. Furthermore, you can mill only one shade at a time, thus tying up your mill.

The ArgenZ Anterior Value Shaded Disc System is a collection of pre-shaded super translucent zirconia that covers all 16 shades of the VITA Classic shade guide with just six value-shaded discs. Each disc covers 2-3 shades based on value and chroma, requiring much less inventory and mill time. No green stage shading is required. You simply design, mill, sinter, and stain and glaze.

The discs are as follows:
? Disc 1: Shades A1, B1
? Disc 2: Shades A2, B2, A3
? Disc 3: Shades C1, D2
? Disc 4: Shades C2, D3, D4
? Disc 5: Shades A3.5, B3, B4
? Disc 6: Shades A4, C3, C4
