Most recently, one of the materials that have been used a lot in dental implants, which are zirconia block. The zirconia blocks are introduced as an alternative option for metal-ceramic dental restoration. When compared to the traditional methods, the zirconia restorations have better esthetic due to their excellent optical properties.
But when compared to the traditional zirconia block, the multilayered block has various advantages. So, let’s see the huge difference between traditional and multilayered zirconia blocks.
What is multilayered zirconia?
In the traditional zirconia block, the manufacturing process consists of an additional step where you need to lay the colors step by step. So, it will get the original beauty effect, but if you take the multilayered zirconia, you don’t have to do the above-mentioned additional process. As it consists of 6 layers and vita shade of 16 colors are available, so it will give an aesthetic effect.
Not only the color, but also the multilayered zirconia block comes with a lot of other benefits than traditional zirconia. Some main advantages are its durability, high biocompatibility, high strength mechanical properties, and it will give a permanent result with its optimal aesthetic property.
Other than this, the multilayered zirconia block will have a natural transition, higher transparency, and a top aesthetic restorative effect. This makes many doctors choose multilayered zirconia, and even they are recommending it for many patients because of its excellent results.
Here are the features of the multilayered zirconia block which will let you know how advanced it is when compared to the traditional zirconia block;
- Comes with an excellent quality
- Higher strength
- Higher translucency
- Have superior mechanical properties
- It has six layers of color natural transition
- It gives a fluent line top aesthetic effect
- Compatible with open CAD/CAM system
- It has good aging resistance and biocompatibility
Difference between monolithic and layered zirconia:
Both monolithic and layered zirconia comes with a primary goal of offering minimum damage and maximum longevity. But still, it comes with major differences such as;
- As the layered zirconia is stacked over the core of the restoration, it offers a flexural strength of 600 to 1200Mpa. While the monolithic restoration will offer higher flexural strength of 900 to 1400Mpa.
- The layered zirconia is mostly placed in the posterior zone or in the anterior zone for a short span of time or posterior bridges. The monolithic will match the natural dentin and enamel, which is considered the biggest advantage
- The polished unglazed monolithic resulted in less teeth wear when compared to the layered zirconia
How strong are zirconia bridges?
Even though ceramic materials have been widely used in the dental industry, they still lack the strength and durability which is required for posterior restorations. That is when zirconia was introduced in the dental industry, and it was the solution to various problems as it comes with excellent strength and aesthetics.
Zirconia is strong enough and also compatible well with the tissues. Even the zirconia block is considered the best option for people who have metal allergies. In that list, Zirconia Bridge is considered to be the strongest material, comes with great biocompatible, and also offers highly aesthetic choice.
This type of solid zirconia bridge is made from pure zirconia, so it offers a flexural strength of 1200Mpa. It is an extremely strong material, and it is the best suitable for patients who are having bruxism. This material for sure will increase customer satisfaction.

The high-strength multilayer zirconia block is the latest generation of the dental multilayer zirconia block, and it is specially developed using the multi-layer concept. The best part of this block is that it will match the natural shade gradient in the teeth. Here, the zirconia base is coated with porcelain to get the natural restoration look.
This is made by milling the porcelain which is fused with a zirconia crown, and then it is developed using computer-aided design or computer-aided manufacturing technology. Here are the features of the high-strength 1200Mpa zirconia block;
- The six-layer transitional gradient color gives seamless look from the enamel layer to the body dentin layer
- It offers great aesthetic translucency of 49% at incisal and 40% at cervical
- It offers bending strength of 600Mpa at incisal and 1200Mpa at the cervical region
- Comes with vita 16 plus blench shade such as BL1, BL2, BL3, BL4
This type of zirconia block can be used to make bridges, crowns, implants, and veneers, and is most recommended for the posterior crown as it has a high bending strength of 1200Mpa.
The anterior multi-layer zirconia block is an Ultra Transmittance Multi-Layer (UT ML) block. It is processed by CAD/CAM dental block multilayer zirconium oxide and with a natural color gradient. This block consists of six layers of zirconia in nature transition shades, so it will allow the fabrication of prosthesis-colored restoration.
It will save a lot of time, and let’s check the features of this anterior zirconia block;
- Comes with super translucency of 49% which is from incisal to the cervical region
- Offers high flexural strength of 700Mpa
- Six layers of natural color gradient transition come seamlessly
- Offers vita 16 plus blench shade such as BL1, BL2, BL3, BL4
It is mainly used in the fabrication of highly aesthetic restoration for crown and bridge restoration in the anterior region and is also most suitable for the veneer.
This is an original zirconia block, and it comes with a non-shaded variation, which can be used as a base to achieve a range of hues. This is a versatile product as it works with the most well-known brands of staining liquids.
- It has a super translucency of 43%
- Offers a strength of >1000Mpa
- The disc height ranges from 10 mm to 25 mm
- Compatible with CAD/CAM
It is mainly used to manufacture customized crowns and bridges, implant veneers, and others, especially in the fixed zirconium prosthesis.
