The bioactive chemistry of Dentsply Sirona Restorative’s Calibra Bio Cement is designed to work naturally with the tooth structure to form a self-repairing layer of hydroxyapatite for improved marginal integrity. Also, its unique Calcium Aluminate Ionomer chemistry delivers seamless adaptation toward the tooth structure at the cement-tooth interface, the company reports. Calibra Bio Cement reduces microleakage as well, Dentsply Sirona Restorative says.
When Calibra Bio Cement reacts with water, calcium aluminate (CA) particles in the cement dissolve, releasing calcium and aluminate ions. When the level of calcium and aluminate ions reach a sufficient concentration, hydrates crystallize around remaining CA particles, creating a seamless adaptation toward the tooth structure at the cement-tooth interface, according to the company.
