Classification factors for dental zirconia blocks

The classification factors of dental zirconia blocks mainly include the following aspects:

1. Color:

- The color of zirconia blocks is a manifestation of their intrinsic properties and an important factor to consider when selecting.

- At present, zirconia blocks are mainly divided into white and Asian skin colors, but can also be customized according to demand.

2. Transparency:

- Transparency refers to the refractive index of the material, which affects the coordination and aesthetics of the restored tooth with the surrounding teeth.

- The selection of zirconia blocks with the right transparency is essential to improve patient satisfaction.

3. Crystal structure:

Zirconia has different crystal structures, such as monoclinic (m), orthorhombic (or tetragonal, t), and cubic (c), which affect the physical and chemical properties of the material.

- Zirconia blocks with different crystal structures are suitable for different dental restoration needs.

4. Brands and manufacturers:

- There are several well-known zirconia block brands in the market, such as ZEUS, pla-plus, Shonton and Weeden.

Different brands and manufacturers of zirconia blocks may have different characteristics, quality and prices.

5. Preparation method:

The preparation method of zirconia blocks, such as hot water, sol-gel or vapor deposition, may also be a factor in their classification.

- Different preparation methods may affect the microstructure and properties of the material.

It should be noted that the above classification factors are not independent of each other, and they may affect each other to jointly determine the final performance and application scenarios of zirconia blocks. When selecting dental zirconia blocks, these factors should be taken into account to meet the specific needs of the patient and the desired aesthetic effect.
