The most commonly used type of zirconia for dental CAD/CAM is yttrium-stabilized tetragonal zirconia polycrystalline (Y-TZP) zirconia. Y-TZP is a very durable and strong material, making it ideal for many dental applications including crowns, bridges and implants.
In recent years, monolithic zirconia blocks have become increasingly popular.
Monolithic zirconia blocks are made from a single layer of zirconia and are often used to create full contour zirconia restorations. Monolithic zirconia blocks have several advantages over traditional zirconia restorations:
- They are stronger and more durable.
- They are more permeable, which can provide a more natural appearance.
- They are shaped more easily. However, monolithic zirconia blocks can be more expensive than traditional zirconia restorations.
Types of zirconia blocks used in dentistry include:
- Monolithic zirconia blocks: Monolithic zirconia blocks can be used to create many restorations, including crowns, bridges, implants, and inlays/onlays. It is especially used in the back area of the mouth, where durability is more important than aesthetics.
- Multilayer - Multilayer zirconia blocks: Multilayer zirconia blocks are formed by combining zirconia layers of different permeability. This allows restorations with a more natural color transition. Multilayered zirconia blocks are frequently used to create restorations in the front area of the mouth where aesthetics are a priority. It is also a good option for patients who offer a natural look and who are willing to pay more.
- Preshaded - Pre-colored zirconia blocks: Pre-colored zirconia blocks are already colored, which can eliminate the need for additional staining or coating. This can save time and money in the production process. Pre-colored zirconia blocks can be used to create restorations in any area of the mouth. It is suitable for patients who want a quick and easy production process.
- Translucent - Translucent zirconia blocks: Translucent zirconia blocks are extremely permeable and suitable for use in the front area of the mouth. Permeable zirconia blocks are frequently used to create restorations in the front area of the mouth where aesthetics are a priority. It is also a good option for patients who offer a natural look and who are willing to pay more.
- Super Translucent - Super Translucent zirconia blocks: Super translucent zirconia blocks are even more translucent than permeable zirconia blocks and are suitable for patients with high aesthetic demands. Super Transulcent zirconia blocks are frequently used to create restorations in the front area of the mouth where aesthetics are a priority. It is also a good option for patients who offer a natural look and who are willing to pay more.
You can contact us to make a compatible sintering program for the block you choose. Please review the sintering programs we have prepared for frequently used blocks, adhering to the official manufacturer's recommendations:
Tegra sinter furnaces have been updated to be compatible with all block types. You can perform excellent quality sintering by applying heating and cooling curves with sensitivity up to 1 C/min. With controlled cooling and timed chamber opening, you can prevent the cracks you encounter in other furnaces.
