What Are the Different Types of Dental Zirconia Blocks Available on the Market?
2024-08-15
Dental zirconia blocks come in several types, each designed to meet specific needs in dental restorations. Here’s a breakdown of the main types:
1. White Zirconia Blocks
- Description: These blocks are uncolored, allowing for custom staining to match the patient's natural teeth. They are ideal for precise color matching and are used in various applications where external coloring is applied.
- Subtypes:
- HT Plus: Offers robust strength (1350 MPa) and moderate translucency (40%).
- ST Plus: Provides a balance of strength (1200 MPa) and translucency (43%).
- SHT: Higher translucency (46%) with slightly lower strength (1000 MPa).
- UT: Maximum translucency (49%) with lower strength (700 MPa), suited for highly aesthetic restorations.
2. Pre-Shaded Zirconia Blocks
- Description: These blocks come pre-colored, which simplifies the restoration process by eliminating the need for additional coloring. They offer consistent color and are convenient for quick, natural-looking results.
- Subtypes:
- HTPC: Affordable with high strength (1350 MPa) and moderate translucency (40%).
- STPC: Balances strength (1100 MPa) and translucency (43%).
- SHTC: Higher translucency (46%) while maintaining good strength (1000 MPa), suitable for aesthetic applications.
3. Multilayer Zirconia Blocks
- Description: These blocks have multiple layers with varying shades, strengths, and translucencies, replicating the natural gradient of teeth for enhanced aesthetics.
- Subtypes:
- Normal Multilayer: Features a gradient in shade, maintaining consistent strength and translucency.
- Gradient Multilayer: Provides a more complex gradient in shade, strength, and translucency for a highly natural appearance.
- UT Multilayer: Combines high translucency (49%) with multilayer technology for a natural gradient effect.
- SHT Multilayer: Offers good strength (1000 MPa) and translucency (46%) with a gradient effect.
- 3D Plus Multilayer: Wide range of strength (700 to 1050 MPa) and translucency (45% to 57%).
- 4D Plus Multilayer: Advanced gradient in strength (700 to 1200 MPa) and translucency (43% to 55%).
- 4D Pro Multilayer: Premium option with enhanced gradient effects in both strength (750 to 1200 MPa) and translucency (43% to 57%).
Choosing the Right Zirconia Block
Selecting the appropriate zirconia block depends on factors like the desired aesthetic result, required strength, and translucency. Each type is tailored to meet specific needs in dental restorations, ensuring both functional and aesthetic outcomes.
