Clinical Evidence

Bench testing only. Testing included shelf life, ISO 10993-5 (cytotoxicity), ISO 10993-10 (sensitization and irritation), ISO 10993-11 (oral mucosa irritation), and physical properties (appearance, volume, packaging, uniformity, chemical solubility).

Technological Characteristics

Water-based solution with inorganic pigments. Non-sterile. pH 5.5-8.0; boiling point 100°C; density 1.00-1.10 g/cm^3; 100% water soluble. Applied via brush or immersion. Tested per ISO 10993 standards for biocompatibility.

Indications for Use

Indicated for individual tooth shading of zirconium dioxide dental restorations. Intended for use by certified dental technicians for individual dental patients.

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.
