The cordless Tri Auto ZX is the only endodontic handpiece with a built-in apex locator, providing the capability and convenience to electronically monitor the root canal before, during and after instrumentation. With the combined technology and accuracy of the Root ZX apex locator, the Tri Auto ZX can significantly increase accuracy and safety. The Tri Auto ZX also offers greater control and flexibility with the adjustable torque settings. The choice of automatic or manual mode operations provide versatility. The three automatic functions include: Auto Start/Stop, Auto Apical Reverse and Auto Torque Reverse.

  • Shapes and cleans root canals while monitoring the files position inside the canal
  • Measures the length of the root canal using the apex locator

“I haven't picked up a hand file in years since the Tri Auto ZX can also serve as a canal locator. The advantage of having an endo file secured in a handpiece means no dropped files which works wonders when a rubber dam isn't possible.”
