Dental Zirconia
Zirconia Disc is a high-performance all-ceramic material made of high-purity zirconium oxide powder and an appropriate amount of stabilizer through an advanced sintering process. The product has extremely high density and bending strength, ensuring that it remains stable and durable during long-term chewing. Its pre-sintered state is convenient for cooperation with CAD/CAM systems to achieve precision processing and meet the needs of various crowns, bridges and full-mouth restorations. Zirconia Disc has excellent aesthetic performance. Its natural gradient color and good light transmittance can perfectly restore the optical properties of natural teeth. It has excellent biocompatibility and is not easy to cause rejection reactions in oral tissues. Strict quality inspection systems and international certifications ensure that each piece of Zirconia Disc meets the standards of high-end dental restoration materials, providing safe, stable and precise material guarantees for clinical use.

Attention
● Prepare teeth into obviously sloping shoulder or round shoulder.
● The milling thickness of edge of cervical region should be at least 1mm.
● Occlusal surface and incisal need to grind off 1.5-2.0mm.
● Knuckle radius should be 0.7mm.
● Axial surface aggregation degree should be 6-8 degree.
● For bridges, adjacent abutment teeth should be parallel between each Other to avoid undercut.
