Dental zirconia porcelain pieces and ordinary porcelain pieces have significant differences in many aspects, mainly reflected in the material composition, performance characteristics, application fields and manufacturing technology.
First, material composition
Dental zirconia porcelain block: mainly composed of zirconia (ZrO2), usually add a small amount of alumina (Al2O3) and other stabilizers (such as yttrium oxide Y2O3) to improve its mechanical properties and chemical stability. This material has the characteristics of high density, high strength and high hardness.
Ordinary porcelain pieces: diverse composition, may include feldspar, quartz, kaolin and other mineral raw materials. Ordinary porcelain pieces are mainly used in daily utensils, decoration and other fields, and their material composition and performance requirements are relatively low.
Second, performance characteristics
Dental zirconia porcelain block:
1.High strength and high hardness: can withstand large bite force, not easy to break or wear.
2. Excellent biocompatibility: It has good compatibility with human tissues and will not cause allergic reaction or rejection.
3. Good chemical stability: stable in acid-base environment and humidity environment, not easy to chemical reaction.
4. Beautiful and realistic: natural color, good transparency, can well imitate the appearance of natural teeth.
Ordinary porcelain pieces:
1. Performance varies by use, but is usually not as outstanding as dental zirconia porcelain pieces in terms of strength, hardness and wear resistance.
2. The biocompatibility and chemical stability are also relatively poor, which is not suitable for medical fields such as oral restoration.
Third, application field
Dental zirconia porcelain block: widely used in the field of dental restoration, such as the production of dental crowns, dental Bridges, veneers and other restorations. Its excellent performance can meet the high requirements of oral restoration materials.
Ordinary porcelain pieces: mainly used in daily utensils, decoration, construction and other fields, such as tiles, tableware, vases and so on.
Fourth, the production process
Dental zirconia porcelain block: The production process is complex and fine, including raw material preparation, molding, sintering, machining and post-treatment and other steps. Among them, the sintering process is particularly critical, requiring strict control of temperature and time to obtain the required density and mechanical properties.
Ordinary porcelain block: The production process is relatively simple, mainly including raw material mixing, molding, drying and firing steps. Different uses of ordinary porcelain block in the production process may be different, but the overall difficulty and complexity is lower than dental zirconia porcelain block.
To sum up, there are significant differences between dental zirconia porcelain pieces and ordinary porcelain pieces in material composition, performance characteristics, application fields and manufacturing processes. Dental zirconia porcelain is widely used in the field of dental restoration because of its excellent properties, and has become one of the important materials in modern dental restoration.
