Ding! The wretched sound of a nickeltitanium (NiTi) file breaking in a patient's
tooth. Ding! That was the sound of the
cash register when it came to pay for NiTi
files. For many years that was the duality
of nickel titanium instruments. You had
these wonderfully efficient files that far
surpassed the shaping instruments before
them, but that still had two major flaws-
breakage and cost.
In 1988, Dr. Harmeet Walia presented
the modern use of NiTI rotary instruments in endodontic therapy and the path
of future treatment changed forever. The
benefits of NiTi, such as the ability to
negotiate curved canals and reduce transportation made the shaping of root canals
significantly more efficient and predictable. Early NiTi rotary instruments were fairly rigid and lacked
the advances in metal chemistry
