EZ-Fill Bi-Directional Stainless Steel Spiral Refill Kit, Assorted Lengths (1 x 21 mm, 3 x 25 mm), 4/Pk, 1600-01

The EZ-Fill Bi-Directional Stainless Steel Spiral Refill Kit contains four spirals in assorted lengths (one 21 mm and three 25 mm) designed to thoroughly coat root canal and lateral canal walls without forcing cement apically. The reverse spirals on the apical end rotate in an unwinding direction out of the canal, preventing instrument binding, and unlike thermoplastic techniques there is no shrinkage upon cooling. The spirals are highly radiopaque and compatible with all bonding agents and composite materials.
