Wirobond C
Wirobond® C – Cobalt-chrome metal-to-ceramic alloy
Nickel- and beryllium-free.
Simple processing thanks to reliable casting time recognition.
Carbon-free composition – particularly well suited for laser welding.
The element cerium ensures high bond strength with the ceramic, minimising the risk of subsequent flaking or chipping.
Low thermal conductivity – protects the pulp and ensures high wearing comfort for the patient.
Biocompatible and corrosion-resistant thanks to a firmly-adhering passive layer.
Type 4: Indicated for prosthetic restorations or sections thereof with thin cross-sections exposed to very high loads, e.g. removable partial dentures, clasps, veneered crowns, long-span bridgework or bridges with small cross-sections, bars, retainers, implant-supported superstructures.
