SHOFU BLOCK & DISK H.C

Intended to provide clinicians with the capability of restoring teeth in a single appointment, SHOFU Block & Disk HC represents a new generation of CAD/CAM composites. This innovative material features a formulation designed to minimize flaws attributed to conventional ceramics.

Composed of 61% zirconium silicate, a densely packed nanofiller of SHOFU Block & Disk HC forms a skeleton which uniformly absorbs masticatory forces and promotes resistance to breakdown phenomena. When compared to other CAD/CAM materials, SHOFU Block & Disk HC manifests better machinability in terms of milling time, damage tolerance, wear of milling instruments, and the ability to be fabricated in a very low thickness.

The high flexural strength of 191 MPa and Vickers hardness of 66 Hv0.2 make SHOFU Block & Disk HC a good candidate for both anterior and posterior restorations, implant-supported cases, and long-term provisionals. Additionally, the hardness of the material also demonstrates values closer to dentin, thus no excessive antagonist wear can be observed, which is a concern when using aesthetic and high-strength ceramics.

■ Universal indications – anterior/posterior crowns, inlays/onlays, veneers

■ Faster milling; better accuracy and marginal integrity

■ No firing/sintering – simplify the workflow

■ Can be adjusted/repaired intraorally

■ Life-like aesthetics with fluorescence of natural dentition

■ BPA-Free

Dentition-like light transmission makes this optimally balanced HYBRID CERAMIC ideal for the production of highly aesthetic anterior restorations. Thanks to its excellent physical properties, it can also be used to create posterior restorations, absorbing occlusal stress and providing highedge stability.

With superior flexural strength and low flexural modulus, the material has excellent capability to diffuse stress, making it an ideal alternative to lithium disilicate and zirconia.

SHOFU Block & Disk HC is milled quickly and precisely and polished to a high gloss in a very short time, and the restoration can be cemented or screw-retained immediately.

NATURAL AESTHETICS WITH TWO-LAYER HC

HC Two-Layer (A3.5)

HC One-Layer (A3.5)

The Two-Layer SHOFU BLOCKS HC efficiently create aesthetically pleasing anterior and posterior restorations. The bilayered BLOCKS are modeled after the layering of natural teeth with a chromatic opaque dentin layer and a translucent layer of enamel. Effortlessly achieve consistent and accurate shade matching while reducing chairside time and treatment cost.

SHOFU BLOCKS HC Two-Layer Ratio

Mimics natural dentition’s optical properties of light diffusion and anisotropy.

SHOFU BLOCKS & Disks HC can be milled wet or dry in all standard milling units.

The optical properties of SHOFU BLOCKS & Disks HC demonstrate the translucency and light diffusion of natural teeth and blend with the surrounding tissue with ease.

The proprietary microarchitecture of the material supports high wear resistance and superior gloss retention allowing for a broad range of indications.

SHOFU CAD/CAM composite, BLOCKS & Disks HC, are manufactured in one- and two-layer BLOCKS and disks. They are available in common tooth shades and translucencies, based on the VITA* Classical shade system.

SHOFU BLOCK & DISK HC FINISHING & POLISHING TECHNIQUE

SHOFU BLOCKS & Disks HC can be easily finished, polished, and adjusted intraorally with the same instruments as direct resin composites. Furthermore, they can retain their gloss, shade, and surface anatomy nearly as effectively as traditional ceramics.

OUTSTANDING WEAR RESISTANCE

The proprietary microstructure of SHOFU Block & Disk HC and its spherically-shaped high-density filler particles achieve greater polishability and higher gloss retention than other CAD/CAM restorative materials.

EXCELLENT COLOR STABILITY

Food and drinks discolor both natural dentition and composite restorations. SHOFU Block & Disk HC has proven to demonstrate higher resistance to staining and better gloss retention as compared to other CAD/CAM materials.

REMARKABLE HIGH GLOSS FINISH

SHOFU Block & Disk HC innovative microstructure creates a smooth and durable surface finish. A natural gloss can be achieved with a few intermediary steps.
