Tri Auto ZX2 is a compact, cordless motor with a built-in apex locator. It may be used for achieving apical patency and creating a glide path with the Optimum Glide Path (OGP) function. Responsive, the handpiece allows subtle and delicate manipulation of the file, facilitating faster and safer treatment even in constricted or extremely curved canals. Proven OTR technology also helps to reduce the possibility of file jamming, breakage, and ledge formation.
