Synergy in core build-up restorations
Teeth with extensive dental caries often demonstrate a high loss of substance, these teeth are often treated endodontically. In such cases, root posts stabilize large-volume build-ups and anchor them into the root canal.
Rebilda Post is a glass fibre-reinforced composite root post with a radiopacity of 350 % aluminium equivalent value. The embedding of glass fibres in the composite matrix leads to high fracture resistance and flexural strength with elasticity similar to dentine. This causes forces to be distributed on the surrounding dental hard tissue, without leading to selective peaks of force in the root of the tooth.
The dual-curing composite Rebilda DC is used in this process, both for bonding of the root post, as well as for the core build-up. An ideal core build-up forms a so-called monoblock of the components used. This monoblock is equivalent in its physical properties to dental hard tissue and responds to stress in the same way.
Systematic build-up reconstruction
All components needed for a stress-free coronal build-up, with or without root post, in a maximum of five steps, are contained in the Rebilda Post System set: Rebilda DC as a fixation and build-up composite; Futurabond DC, dual-curing self-etch bond; Rebilda Post, the glass fibre-reinforced composite root post with exactly adjusted pilot and root canal burs; and Ceramic Bond, a high-strength coupling silane, which further increases the bond between Rebilda DC and Rebilda Post.
