Available in 0+1 and 1+2 Flexi Post Fiber's serrated head permits greater retention of core material. The second tier of the shank increases the intimacy of fit between the post and the natural point at which the canal widens, thereby reducing destructive long lever arms. The flexi-post fiber vent releases internal hydrostatic pressure upon cementation. Threaded design provides greater retention than passive fiber posts without the need for a bonding agent. Made from proprietary, epoxy reinforced, high strength s-glass fiber. Contains: 6 posts size 0, 6 posts size 1, 1 tap, 1 primary reamer, 1 secondary drill, external wrench (fits both post sizes), 1 depth gauge
