The patented EZ-Fill bi-directinoal spiral whips EZ-Fill non-eugenol epoxy cement laterally preventing cement being driven past the apex providing a complete seal when used in conjunction with gutta percha. Thoroughly fill canals quickly & economically. Avoids shrinkage associated with lateral condensation & thermoplastic gutta percha. Eliminates the need for expensive thermoplastic equipment. Coronal path of exit for excess cement eliminates stress.
