Patented Flexi-Flange is a "specific-use post" with a parallel-sided, threaded, split-shank design. Scientifically designed countersinking flange for cases lacking supportive coronal dentin along with a second tier, which produces an intimate fit with optimal metal-to-dentin contact, offering maximum stability. Split-shank gradually collapses as post is inserted into canal, effectively reducing insertional stresses.
