What Are Lithium Disilicate Blocks and Their Role in Dentistry?
What Makes Up Lithium Disilicate and Its Key Features?
Lithium disilicate is a glass-ceramic material prized for its strength and clear, attractive look. It contains lithium oxide (Li₂O), silicon dioxide (SiO₂) and minor elements that create its crystal structure. This setup allows a special process to make it strong and visually clear.
XANGTECH’s lithium disilicate stands out in dental work. It stays chemically stable and has strong bending resistance, making restorations last longer. With a Vickers hardness of 5400, it holds up well under chewing pressure.
How Do Lithium Disilicate Blocks Improve Dental Work?
These blocks are made for CAD/CAM dental systems. They let dentists craft precise restorations like crowns, bridges, or veneers. Their clear appearance mimics natural teeth, giving a realistic look.
For visuals, lithium disilicate shines in matching tooth color and clarity. It’s also simple to shape, which saves wear on milling tools and extends their use.
When Are These Blocks the Best Choice?
Dentists select lithium disilicate when they want strength and beauty. It’s perfect for front teeth where looks are most important. But it’s also tough enough for back teeth dealing with usual chewing pressure. Its durability helps restorations stand up to everyday wear, ideal for crowns, bridges, veneers and tiny fillings like inlays or onlays.
XANGTECH: A Trusted Name in Lithium Disilicate
Who Is XANGTECH and What Do They Provide?
XANGTECH brings 11 years of know-how in dental materials like zirconia, PMMA, milling tools and lithium disilicate blocks. Based at Nanyang Liandong Biotechnology, we serve professionals in over 20 countries.
Our aim is simple: offer complete solutions with great service to meet dentistry’s changing needs.
What Sets XANGTECH’s Lithium Disilicate Apart?
Strength and Visual Appeal
Our blocks hit industry standards with a strength of 400 (±60 MPa) after processing. They handle daily chewing without breaking down.
For looks, they offer clear options (high or low translucency) and match common tooth shades like A1–D2 or BL1–BL4 for natural results.
Works Well with CAD/CAM
Our blocks fit smoothly into digital workflows. They’re easy to mill, reducing tool wear and saving costs while keeping precision.
Their quick crystallization process cuts lab time without losing quality, perfect for busy labs aiming to work faster.
How Different is XANGTECH’s Lithium Disilicate from Other Lithium Disilicate Blocks?
Are There Noticeable Differences in Performance Between Brands?
All lithium disilicate blocks have similar basics—they’re glass-ceramic and tough. But brands vary in things like how fast they harden, how well they mill, how true their colors stay, and how strong they are under strain. Some focus on speed but may not match colors well or last as long.
Evaluating Key Factors: Strength, Translucency, and Processing Time
Flexural Strength and Fracture Resistance
The toughness of lithium disilicate matters a lot for good results. Most blocks give bending strengths around 360–400 MPa after hardening. Only those with reliable quality checks keep this strength steady across all batches. XANGTECH’s lithium disilicate hits 400 MPa (±60 MPa) in biaxial strength, so restorations can take everyday chewing forces.
Optical Properties and Shade Matching
Clarity and color accuracy are crucial for front teeth fixes. High-translucency (HT) types let light shine through like real enamel. Low-translucency (LT) ones are better for covering stained teeth or metal bases. XANGTECH’s lithium disilicate offers shades like A1, A2, A3, A3.5, B1, B2, C1, C2, D2, BL1, BL2, BL3, and BL4, making color matching precise.
Milling Efficiency and Firing Requirements
Production speed makes a difference. XANGTECH’s lithium disilicate hardens simply and quickly. This saves time in the lab and improves work flow. It also mills easily, which helps keep tools from wearing out fast, cutting costs over time.
What to Consider When Picking a Lithium Disilicate Block?
Strength or Looks: What Matters More?
When choosing lithium disilicate blocks like XANGTECH’s, decide if strength (for back teeth) or aesthetics (for front teeth) is the priority. Our high-clarity options suit cosmetic needs, while low-clarity ones hide darker tooth bases better.
Does Processing Time Impact Workflow?
Labs with tight schedules need fast processing. Our blocks’ quick crystallization helps meet deadlines while keeping quality high.
How Does Cost Factor In?
Cost isn’t just about price. Easy milling extends tool life and our lithium disilicate blocks balance top performance with fair pricing, offering value over many restorations.
Where Are Lithium Disilicate Blocks Used?
Common Uses: Crowns, Veneers and More
Lithium disilicate works for many restorations, like full crowns (especially front teeth), thin veneers, or smaller fillings like inlays. Its strength and beauty make it versatile.
It handles chewing forces well, fitting premolar areas with moderate pressure.
Are They Good for Front and Back Teeth?
Yes, with strength around 400 MPa and great looks, lithium disilicate works for front teeth (where appearance rules) and back teeth (where function matters). For bridges longer than three units, zirconia might be better for extra toughness.
