This article will give you a detailed introduction to dental zirconia discs, including price, model, use and other aspects. After reading it, you will have a deeper understanding of HONCHON zirconia discs.
1.What is dental zirconia disc？
Dental zirconia disc is made of high-purity zirconia as the main raw material, with yttrium oxide as a stabilizer, and is dry-pressed, cold isostatically pressed, and pre-sintered. Zirconia is a ceramic material known for its durability and biocompatibility. Honchon dental zirconia discs are made using a unique dry-pressed, cold isostatically pressed manufacturing process into zirconia blanks, which are precision milled and sintered with CAD/CAM system processing to create strong, beautiful-looking dental restorations.
2. What are the physical and chemical properties of dental zirconia disc？
Zirconia (%) (ZrO2+ Y2O3+ HfO2+ Al2O3) | Y2O3 (%) | HfO2 (%) | Al2O3 (%) | Other oxides (%) (Fe2O3, Er2O3and MnO) |
≥99.0 | 4.0 to 10.0 | ≤ 5 | ≤ 0.1 | ≤ 0.9 |
Uniformity: The inorganic pigments used to produce the color of sintered dental ceramics or the organic pigments used for color labeling should be evenly dispersed in the zirconia porcelain blocks for all-porcelain dentures.
Physical and chemical properties:
Flexural strength
Model | Flexural strength | Class |
HT, ST-C, ST-ML, SHT-C, ML, Pro-ML | >800 | 5 |
UT-C, UT-ML | >500 | 4 |
Chemical solubility: <100 μg/cm2.
Shrinkage factor: The shrinkage factor by which the dimensions of the partially sintered material should be within the range of 1.220-1.260, and the absolute accuracy of the shrinkage factor shall be ±0.002.
Radioactivity: Dental ceramic materials shall not have an activity concentration of more than 1.0 Bq.g-1 of uranium238.
Linear thermal expansion coefficient: The linear thermal expansion coefficient should not deviate from the manufacturer's marked value of 10.4 ± 0.5 × 10⁻⁶ K⁻¹.
Fracture toughness
Model | Fracture toughness (MPa·m¹/²) |
HT, ST-C, ST-ML, SHT-C, ML, Pro-ML | ＞5.0 |
UT-C, UT-ML | >3.5 |
3. Dental zirconia disc prices？
The price of Dental zirconia disc ranges from USD 20 to USD 120. The specific price depends on the model thickness and quantity. Please feel free to consult us for the best price.
4. What models of dental zirconia discs are available?
HONCHON zirconia tray models include 8 models, including HT, ST-C, ST-ML, SHT-C, ML, Pro-ML, UT-C, and UT-ML. To learn more about all types of honchon's zirconia blocks, please click here.
5. Application of dental zirconia disc
Dental zirconia discs are widely used in the production of various types of dental restorations. They are suitable for the production of crowns, bridges, veneers, inlays, high inlays and implant abutments. Due to its high strength and excellent aesthetics, zirconia is commonly used for the restoration of anterior and posterior teeth. The different transparency and strengths enable technicians and dentists to choose the right type of zirconia for the clinical needs - whether for single crowns or full bridges.
