Ionosit Baseliner.
The ‘stress breaker’ for gap-free restorations.

Ionosit Baseliner

Ionosit Baseliner ensures stress-free composite restorations thanks to its shrinkage compensation.

Ionosit Baseliner – the ideal
one-component underfilling material for
your composite restorations

Ionosit Baseliner combines the optimum properties of glass ionomers and composites in one material. Ionosit Baseliner expands by approximately 1% and this expansion counteracts the polymerization shrinkage stress of the shrunken composite. This efficiently prevents the formation of marginal gaps and associated bacterial penetration. The dentinal tubules are sealed and the pulp is protected from bacterial influences. This is a reliable and permanent means of preventing pulp damage and postoperative sensitivity. Ionosit Baseliner serves as a stress-breaker for the entire cavity as it counteracts the polymerization shrinkage of the restoration. Structural stress or micro-fractures in the composite are minimized. This guarantees durable, functionally reliable restorations.

Ionosit Baseliner is applied in a layer of 1 mm thickness between dentin and composite. Ionosit Baseliner releases fluoride and zinc ions. This provides protection at the junction between the tooth surface and the restoration, a particularly vulnerable area. The release of these substances forms a protective barrier for the tooth. The baseliner can be easily applied directly from the syringe.

Ionosit Baseliner prevents micro-gaps, the leading cause of microleakage before they happen. It‘s a fact of life that composites undergo polymerization shrinkage. We rely on adhesives to maintain a strong gap-free bond between composite and dentin, but that doesn‘t always happen. Ionosit Baseliner employs patented controlled expansion technology to reduce the post-polymerization stress which leads to leakage, post-op sensitivity and recurrent decay.

Ionosit Baseliner is a base material for composite and amalgam restorations that can be used to block out undercuts in inlay/onlay restorations.

Ionosit Baseliner is capable of controlled expansion. Thanks to its innovative chemistry, it also forms a connection to dentin. This creates a so-called reaction zone. The crucial advantage: possible gaps created by polymerization shrinkage of the composite material are negated and stress on the dentin interface is reduced.

Ionosit Baseliner in detail

Ionosit Baseliner is applied in a layer measuring 1 mm thick between the dentin and the composite. This releases the fluoride and zinc ions directly into the particularly vulnerable transition zone, creating a lasting, reliable protective barrier for the tooth.
