C14 Low Translucency Lithium Disilicate Blocks Cubes for Sirona Cerec Milling

Designed for clinical situations that demand superior masking capability, these C14 low translucency (LT) glass ceramic blocks provide excellent opacity without sacrificing natural aesthetics. Each 5-piece pack is precision-manufactured from lithium disilicate glass ceramic for reliable performance in Sirona Cerec chairside milling workflows. With post-crystallization strength exceeding 400 MPa, the C14 LT blocks are a dependable solution for restorations over discolored teeth, metal cores, and dark substrates.

Key Features & Benefits

• Superior Masking Power: C14 LT delivers controlled opacity that effectively conceals metal posts, dark dentin, and discolored abutment teeth beneath a natural-looking restoration.
• Balanced Aesthetics: Despite low translucency, the material retains sufficient depth of color and surface luster to create lifelike results after polishing or glazing.
• Dependable Strength: Flexural strength of ≥ 400 MPa provides confidence for both anterior and posterior load-bearing restorations.
• Streamlined Workflow: Single-stage crystallization at 840°C with a 7-minute hold time means fast turnaround from mill to mouth.
• Universal Cementation: Compatible with both adhesive and self-adhesive resin cement systems for clinical flexibility.
• Cerec-Optimized Dimensions: Blocks are precisely sized for Sirona Cerec MCXL, MCX5, and Primemill milling chambers.
• Full Biocompatibility: Zero cytotoxicity, non-genotoxic, and non-irritating to oral tissues per ISO 10993 testing standards.

Technical Specifications

Clinical Applications

• Crowns on Endodontically Treated Teeth: LT material masks the typical dark discoloration of root-canal-treated teeth, providing a uniform, natural result.
• Restorations Over Metal Posts: Prevents gray show-through from metallic substructures, a common challenge with high-translucency materials.
• Posterior Crowns & Onlays: High strength and opacity make C14 LT the go-to choice for functional posterior restorations.
• Multi-Unit Shade Matching: Consistent opacity helps achieve uniform color results when restoring multiple teeth with varying substrate conditions.
• Implant-Supported Restorations: Masks titanium abutment color while delivering tooth-like surface characteristics.

Compatible Milling Machines

Frequently Asked Questions

Q: Is C14 LT suitable for anterior restorations?
A: C14 LT can be used for anterior crowns when the underlying tooth is significantly discolored. For anterior cases with healthy, light-colored substrates, C14 HT may produce a more translucent, natural-looking result.

Q: What cementation protocol do you recommend for C14 LT blocks?
A: For optimal bond strength, etch the internal surface with 5% hydrofluoric acid for 20 seconds, rinse thoroughly, apply silane coupling agent, then bond with a dual-cure or light-cure resin cement.

Q: Can I adjust the shade after milling?
A: Yes. External characterization using compatible stain and glaze materials allows shade adjustment after crystallization. Internal staining prior to crystallization is also possible with some systems.

Q: Do B40 and C14 LT blocks have the same strength?
A: Yes. All lithium disilicate blocks cubes in this line share the same base material and mechanical properties. The difference is solely in shade and translucency level.

Q: How do I clean blocks before milling?
A: No pre-milling cleaning is needed. Simply remove the block from its packaging and insert it directly into the milling machine holder.
