With the dual-curing system for core build-up and post retention based on composite Rebilda DC fluorescent, VOCO introduces a new member of the Rebilda family. Rebilda products have been successfully established worldwide for decades and are highly trusted in dental practices, particularly due to their dentin-like properties. The previous dentin shades, white and blue, are now complemented by a fluorescent variant, further demonstrating VOCO's innovative character. This is the only material for core build-up and post retention with activatable fluorescence. Under ultraviolet A light, the material is so intense that excesses and boundaries of the reconstruction can be excellently detected, especially in the deep subgingival area, significantly facilitating core build-up for the user. And all this without compromising patient aesthetics, as Rebilda DC fluorescent matches the shade of dentin in daylight, making it optimally suitable for highly aesthetic restorations. High similarity to dentin. Additionally, Rebilda DC stands out for its dentin-like properties: the material is very suitable for shaping, like dentin, and exhibits the corresponding hardness so that preparation can be performed easily and the final reconstruction behaves like a natural tooth under load. The dual-curing of Rebilda DC also offers several advantages: even under the most unfavorable conditions for light curing, the material hardens with high final strength and can also be applied in the root canal. If a post is needed for the reconstruction of a severely damaged tooth, the same material can be used for both post adhesion and core build-up. This so-called "monoblock" contributes to an increase in the strength of the entire reconstruction.
