The innovative new SpirapostPFS* (Poly Fiber Strands), exclusively from Zenith Dental, naturally flexes to conform to the shape of the canal, to offer the benefits of a custom fit for all root canal configurations. Due to its unique design, Spirapost is able to adapt to the irregularities of the canal, so it minimizes the removal of tooth material.
