Nickel- and Beryllium-free Co-Cr-W-Mo ceramic bonding alloy for the crown and bridge technique.
Combibond® CroCoCer CCR is a top alloy, which can also be used in difficult situations, such as large bridge sizes. The E modulus – important for the load capacity of crown and bridge constructions – is approximately twice that of precious crown and bridge alloys. This protects against deformations through chewing pressure. Additionally, the high heat resistance as well as the outstanding biocompatibility present Combibond® CroCoCer CCR as a real alternative to precious metal alloys. The bonding strength with ceramics is excellent too. Combibond® CroCoCer CCR is suitable for laser welding.
