This Crown Cement is based on the patented Glass Carbomer® Tech. It is designed for the cementation of crowns with a rapid hardening time. In addition, GCP Crown Cement is100% biocompatible and is therefore 100% safe. With zirconium crowns (ZrO2), a natural fusion is achieved by way of natural ion exchange between the Nano-Fluoride-/Hydroxyapatite of the cement and the interior side of the element, which has been pre-treated with fluorapatite. This process ensures an unprecedented adhesion.A GCP Crown Cement pack contains 10 capsules.
