Abstract

The invention relates to filling systems containing as component i) a sealing system which is capable of bonding to the tooth hard substance, as component ii) a filling material suitable for restorative dentistry, the filling system containing in addition a component iii) in component i) and/or component ii) which reduces the curing of the respective other component by disturbance of the curing mechanism only in the boundary layer between sealant and filling material such that the bonding between components i) and ii) is less than the bonding of component i) to the tooth hard substance.
