Classification of dental zirconia blocks

Dental zirconia blocks can be classified according to different criteria, the following are some common ways to classify:

1. Brands and Manufacturers:

ZEUS Zirconia porcelain block: a well-known brand of Denspar Sinord for the manufacture of porcelain and full porcelain teeth.

pla-plus alumina porcelain block: belongs to the super concentrated product, in addition to excellent wear resistance, but also has good chemical stability and excellent aesthetic effect.

Other brands such as Shandon all-porcelain teeth, YZU bone China block, Weeden zirconia porcelain block, etc., also have their own characteristics and scope of application.

2. Material characteristics and composition:

Traditional zirconia ceramics (such as 3Y-TZP) : using a specific proportion of yttrium oxide as a stabilizer, tetragon-phase zirconia polycrystalline ceramics are widely used because of their good mechanical properties.

3. Color and transparency:

Zirconia blocks are mainly divided into white and closer to natural skin tone types, and different colors of zirconia blocks can be selected according to the patient's gum and tooth color and personal needs.

4. Purpose of use and repair type:

Different types of zirconia blocks vary in strength, and the selection should consider the specific situation of the patient and the quality requirements of the prosthesis.

In summary, the classification of dental zirconia blocks involves several dimensions such as brand, material properties, color and transparency, purpose of use, and strength. In the selection, the actual needs of patients and the expected function of the prosthesis should be considered comprehensively.
