98mm Cad Cam Dental Zirconia Block

 

1. Standardized 98 mm Diameter + Full Thickness Spectrum for Versatile Clinical Applications

This feature combines universal compatibility with flexible thickness options, addressing the common issues of "limited specifications" and "poor adaptability" found in traditional zirconia discs. It also serves as a foundation for improving processing efficiency.

Using the industry-standard 98 mm diameter, the discs are offered in nine graded thickness options including 10 mm, 12 mm, 14 mm, and more. The design fits the fixture size of mainstream CAD/CAM five-axis milling machines. The universal edge notching ensures positioning accuracy within ≤0.01 mm, preventing machining deviations caused by size mismatches.

Advantages:

Full clinical coverage:

Thin (10–16 mm): anterior crowns, inlays/onlays, small restorations

Medium (18–22 mm): posterior crowns, 3-unit bridges

Thick (24–25 mm): full-arch restorations, long-span bridges
➜ One milling machine + this material system can handle all zirconia restoration types.

High machining compatibility:
The 98 mm format is universal across dental CAD/CAM systems. No parameter adjustment or fixture replacement is required - simply mount and mill. Even beginners can operate easily, reducing technician training costs.

Higher material utilization:
Thickness can be selected precisely according to restoration size, avoiding waste from overly thick discs. This increases material utilization by 15%–20%, significantly lowering consumable costs.

2. 600–1350 MPa High Strength for Long-Term Durability and Reliability

Made with ≥99.5% high-purity zirconia powder, stabilized with yttria to form a tetragonal crystal structure, and processed via cold isostatic pressing and precision pre-sintering. The material exhibits a transformation toughening effect: when subjected to impact, tetragonal zirconia transforms to the monoclinic phase, absorbing energy and preventing crack propagation - combining ceramic hardness with metal-like toughness.

Advantages:

Clinically safe and reliable:
With flexural strength of 600–1350 MPa, far exceeding human chewing forces (200–300 MPa), the chipping rate for 3–4 unit posterior bridges is <0.5%, well below industry averages. Even under long-term occlusal load, restorations resist fracture and chipping, reducing after-sales repair.

Excellent long-term stability:
The dense crystal structure and chemical inertness prevent corrosion and aging in alternating acidic/alkaline oral environments.
Service life exceeds 10 years, with 95% survival at 8 years, outperforming resin and glass-ceramic alternatives.

Ideal for high-load regions:
High strength enables safe use in posterior load-bearing restorations, solving the lack-of-strength limitation of traditional esthetic materials (e.g., glass ceramics), achieving a balance between function and esthetics.

3. 41%–55% High Translucency for Natural, Lifelike Esthetics

By controlling zirconia powder particle size (20–50 nm), optimizing sintering shrinkage, and improving internal crystal orientation, light scattering is minimized. Trace optical modifiers further refine translucency, precisely controlling the range to 41%–55%, closely matching natural enamel (45%–55%).

Advantages:

Natural, lifelike esthetics:

41%–45% translucency for posterior restorations (strength-first with baseline esthetics)

48%–55% translucency for anterior esthetics
Restorations display natural enamel-like luster without the "gray shadow" of metal-ceramics or the "flat look" of conventional ceramics.

Streamlined esthetic workflow:
Excellent inherent translucency reduces the need for manual staining and glazing. A single anterior restoration can be finished within 3 minutes, supporting same-day dentistry.

Adaptable to diverse esthetic demands:
Compatible with VITA 16 shade guide and bleaching shades. Even for patients with tetracycline stains, fluorosis, or other complex color conditions, precise shade matching enables seamless blending with natural dentition.
Clinical first-fit success rate improves by 80%.
