Biolight® DRILL-FREE creates a new concept in post-endodontic crown restorations, using well-established principals from construction engineering. Instead of placing a large, traditional post in the center of the canal, multiple smaller and flexible post strands are spread throughout the canal space. The result is a core that is significantly more resistant to deformation before fracture than a no-post or central post restoration, a post that is ideal for all shapes of canals, and an elimination of all the decision and risks associated with drilling a post space.
While many fiber posts simply mimic the shapes of popular metal posts, Biolight DUAL is designed to fully benefit from fiber technology. The larger coronal tapers dramatically improve adaptation throughout the length of the canal. The overall shape offers a superior adaptation to the canal, minimizes the removal of dentin, and keeps the resin cement layer (the weakest link) to an absolute minimum.
