Full-contour zirconia (also known as monolithic zirconia) is a modern, metal-free dental restoration made entirely from zirconium dioxide (ZrO₂). Unlike traditional porcelain-fused-to-metal (PFM) or layered zirconia, monolithic zirconia requires no ceramic veneering, offering a homogeneous, highly durable structure.
Key Features
Exceptional Strength With a flexural strength of 800-1,200 MPa, full-contour zirconia is one of the strongest dental materials available. It is ideal for posterior crowns and bridges, especially in patients with bruxism or high occlusal loads.
Superior Biocompatibility Zirconia is hypoallergenic, corrosion-resistant, and does not cause metal ion release or gum discoloration, making it suitable for patients with metal allergies.
Aesthetic Versatility Modern multilayer zirconia discs offer gradient shade and translucency (e.g., high-translucency for anterior teeth, high-strength for posteriors). Digital staining and glazing techniques further enhance natural appearance.
Wear-Friendly to Opposing Teeth When properly polished or glazed, monolithic zirconia is smooth and causes minimal wear to natural enamel compared to rough or unpolished ceramics.
CAD/CAM Compatibility Full-contour zirconia is fabricated via computer-aided design and manufacturing (CAD/CAM), ensuring precision fit, efficiency, and reproducibility.
