Zirconia discs


Experience the Perfect Trifecta of Esthetics Strength & Efficiency of Zirconia

3D-Pro multilayer zirconia is a dental restorative material designed for crowns and bridges, offering a flexural strength range of 65-1100 MPa and a fracture resistance of up to 6 MPa 1/2. It features a high-speed sintering cycle, ensuring strength, translucency, and aging resistance simultaneously.

  1. Degradation and Transformation: Degradation of zirconia occurs due to tetragonal to monoclinic transformation, especially at temperatures of 200-300°C, leading to micro and macro-cracking. The addition of stabilizers such as yttria can slow down this transformation.
  2. Crystal Phase Systems: Zirconia exhibits different crystal phases (monoclinic, tetragonal, and cubic) depending on temperature and yttria content. Higher yttria content stabilizes tetragonal and cubic phases, influencing translucency and mechanical properties.
  3. Thermal and Optical Properties: Zirconia has low thermal conductivity and specific thermal expansion characteristics. Control over alumina content and yttria content affects light translucency and scattering, impacting aesthetic properties.
  4. Flexural Strength: Flexural strength decreases with increasing yttria content. However, 3D-Pro offers a wide range of flexural strengths suitable for various dental applications.
  5. Monoclinic Resistance: Unique microstructure and chemical formulation of 3D-Pro resist aging degradation, preventing the shift from cubic to monoclinic phase, which enhances its longevity and structural integrity.


What is a Zirconia Disc?

A zirconia disc is a type of dental material commonly used in the fabrication of dental prostheses, such as crowns, bridges, and implant-supported restorations. These discs are typically made from zirconium dioxide (ZrO2), a biocompatible ceramic material known for its durability, strength, and aesthetic qualities. Zirconia discs come in various shapes, sizes, and shades to accommodate different clinical needs and patient preferences. Dental technicians use computer-aided design and computer-aided manufacturing (CAD/CAM) technology to mill or shape zirconia discs into precise dental restorations that closely match the natural teeth in appearance and function. With their excellent mechanical properties and lifelike aesthetics, zirconia discs have become a popular choice in modern restorative dentistry.
