[Light, scanning and electron microscopic studies of the substrate dependence in replacement cementum formation].

The cement genesis obviously does not depend on surface parameters such as the exposition of dentin collagen. It can be reproduced on different surfaces of ceramics and is not bound to substrate. The classification primarily depends on the extent of contact of the cement with the substrate surface. However the integration of Interpore 200 seems to be more physiological compared to the integration of pure synthetic ceramics Osprovit. Yet both porous ceramics show no resorption stability and are therefore replaced by substances of cement. The size of the synthetic hydroxylapatite crystals is important to the bonding stability.
