ENDODONTIC INSTRUMENTS WITH PILOT TIPS AND PARABOLIC CUTTING FLUTES.

摘要

A series of multi-tapered parabolic implements (18) is disclosed for endodontic use. The implements comprise different sections: a pilot tip (20), a first portion ( alpha ) adjacent the pilot tip and a second portion ( beta ) adjacent the shank. The two portions have different tapers. The tapers of the two different portions blend into each other along a parabola-shaped surface.
