1350 MPa 3Y-TZP Zirconia for Long-Span & Masking-Critical Restorations<\/strong><\/p>\n The Hocera HT High-Strength Zirconia Block<\/strong> is developed specifically for high-load restorations and complex substrate conditions<\/strong> where conventional zirconia materials show limitations.<\/p>\n In daily laboratory practice, technicians often face three recurring challenges: Hocera HT zirconia achieves a flexural strength of 1350 MPa<\/strong>, based on a dense 3Y-TZP (yttria-stabilized tetragonal zirconia polycrystal)<\/strong> microstructure.<\/p>\n Because of this material composition, the zirconia core maintains high fracture resistance under cyclic loading<\/strong>, even in posterior regions. Tested according to ISO 6872:2015<\/strong><\/p>\n<\/li>\n Fatigue resistance verified at 1.5 million cycles (ISO 14801)<\/strong><\/p>\n<\/li>\n Connector stability confirmed at 0.3 mm thickness<\/strong><\/p>\n<\/li>\n<\/ul>\n This performance level allows technicians to meet strength requirements without sacrificing anatomical design or occlusal space<\/strong>.<\/p>\n In clinical reality, many restorations involve C3\u2013C4 discolored dentin, metal posts, or titanium bases<\/strong>. Hocera HT offers 38% controlled translucency<\/strong>, which balances light transmission and opacity. Consequently, laboratories can achieve:<\/p>\n Stable shade outcomes<\/p>\n<\/li>\n Reduced reliance on heavy stains<\/p>\n<\/li>\n More predictable anterior\u2013posterior color consistency<\/p>\n<\/li>\n<\/ul>\n Hocera HT is designed for direct bonding to titanium bases<\/strong>, enabling reliable hybrid abutment restorations<\/strong>.<\/p>\n Thanks to its material density and stable coefficient of thermal expansion, the zirconia performs consistently in metal-ceramic replacement cases<\/strong>, eliminating corrosion risks and improving biocompatibility.<\/p>\n Certified under ISO 13356<\/strong><\/p>\n<\/li>\n FDA-cleared for dental restorative use<\/p>\n<\/li>\n Proven bond stability under ISO 9693 conditions<\/p>\n<\/li>\n<\/ul>\n Rather than forcing laboratories into a single technique, Hocera HT supports two validated restorative workflows<\/strong>:<\/p>\n Staining technique<\/strong> Layered porcelain technique<\/strong> Because of this thermal compatibility, the zirconia core and veneering ceramic expand uniformly during firing. During CAD\/CAM processing, Hocera HT demonstrates predictable milling behavior<\/strong> across open systems.<\/p>\n Clean margins with minimal micro-chipping<\/p>\n<\/li>\n Stable performance in thin areas<\/p>\n<\/li>\n Reduced tool wear in high-volume production<\/p>\n<\/li>\n<\/ul>\n During sintering, the material maintains a shrinkage tolerance of \u00b10.5%<\/strong>, which is significantly tighter than the industry average of \u00b11.2%<\/strong>. Hocera HT zirconia blocks are produced in standard open-system formats:<\/p>\n 98 mm \/ 95 mm<\/strong><\/p>\n<\/li>\n 92 \u00d7 75 mm (AG systems)<\/strong><\/p>\n<\/li>\n<\/ul>\n They integrate directly with Roland, DWOS, and Exocad workflows<\/strong>, without adapters or special calibration. Hocera HT is recommended for:<\/p>\n Posterior and anterior long-span bridges<\/p>\n<\/li>\n Full-contour crowns with minimal occlusal reduction (\u22650.5 mm)<\/p>\n<\/li>\n Implant-supported hybrid restorations<\/p>\n<\/li>\n Metal-ceramic replacement cases<\/p>\n<\/li>\n<\/ul>\n By covering multiple indications, the material helps laboratories reduce inventory complexity while maintaining clinical reliability<\/strong>.<\/p>\n <\/p>\n <\/p>\n<\/div>\n <\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":" \u200b\u200bHocera HT Zirconia Block\u200b<\/strong>\u200b:<\/p>\n 1350MPa 3Y-TZP zirconia with 38% light absorption for ultimate masking of discolored abutments & metal substrates.<\/p>\n Certified for 14-unit bridges & titanium hybrid abutments.

\nProduct Background & Material Rationale<\/h3>\n
insufficient strength for long-span bridges<\/strong>, poor masking over dark abutments<\/strong>, and dimensional instability after sintering<\/strong>.
Hocera HT directly addresses these issues<\/strong> through a strength-focused 3Y-TZP formulation combined with controlled translucency and optimized sintering behavior.<\/p>\n
\nMechanical Strength Based on Proven Standards<\/h3>\n
As a result, laboratories can confidently fabricate 6\u201314 unit long-span bridges<\/strong> without over-dimensioning connectors.<\/p>\n\n
\nMasking Performance for Discolored Substrates<\/h3>\n
Therefore, zirconia must provide sufficient masking before any staining or layering begins<\/strong>.<\/p>\n
Compared with standard HT zirconia materials, this formulation improves masking efficiency by approximately 22%<\/strong>, while still maintaining natural brightness.<\/p>\n\n
\nHybrid Abutment & Metal Replacement Compatibility<\/h3>\n
\n
\nDual Workflow: Staining or Layered Porcelain<\/h3>\n
\n
Compatible with brush-on systems such as IPS Ivocolor<\/em> for efficient full-contour restorations.<\/p>\n<\/li>\n
Fully compatible with ceramics such as Creation ZI<\/em>, supported by a 0.02 mm CTE match<\/strong>.<\/p>\n<\/li>\n<\/ol>\n
This significantly reduces the risk of chipping, cracking, or veneer delamination<\/strong>.<\/p>\n
\nMilling Accuracy & Sintering Stability<\/h3>\n
\n
Therefore, marginal gaps consistently remain \u226430 \u03bcm<\/strong>, improving first-fit accuracy and reducing chairside adjustment.<\/p>\n
\nCAD\/CAM System Compatibility<\/h3>\n
\n
As a result, laboratories can standardize one high-strength zirconia solution across multiple machines and indications.<\/p>\n
\nClinical Indications<\/h3>\n
