Intended Use

X-cera Zirconia Blanks are indicated for the production of artificial teeth in fixed or removable dentures, or for jacket crowns, facings, and veneers.

Device Story

X-cera Zirconia Blanks are zirconia-based blocks, discs, or cylinders used as raw material for dental prosthetics. The device is manufactured via uni-axial and iso-static pressing to ensure uniform density. In a dental laboratory setting, a technician uses modern machining equipment to mill the blanks into complex dental shapes, such as crowns, veneers, or denture components. The final prosthetic is then sintered to achieve its final mechanical properties. The device provides a high-strength, biocompatible ceramic material for restorative dentistry, enabling the fabrication of durable, patient-specific dental replacements.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing, including flexural strength, density, porosity, shrinkage/expansion rates, chemical composition analysis, and biocompatibility testing (cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, and genotoxicity) in accordance with ISO 6872, ISO 7405, and ISO 10993.

Technological Characteristics

Materials: Zirconia (ZrO2 88-96%, Y2O3 4-10%, Al2O3 <1%, HfO2 <0.05%, SiO2 <0.5%). Form factor: Blocks, discs, cylinders. Processing: Uni-axial and iso-static pressing. Sintering temperature: 1480°C. Mechanical properties: Flexural strength ≥800MPa (ISO 6872), Elastic modulus 210±15 GPa. Standards: ISO 6872 (Type II Class 6), ISO 10993-1, ISO 7405. Non-sterile.

Indications for Use

Indicated for production of artificial teeth in fixed or removable dentures, or for jacket crowns, facings, and veneers. No specific patient population or contraindications described.

Regulatory Classification

Identification

Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.
