The WaveOne concept, in most instances, provides a single-file shaping technique, regardless of the length, diameter, or curvature of any given canal. In fact, it has been shown that a single-file reciprocating shaping technique utilizing unequal CW/CCW angles is over 4 times safer and almost 3 times faster than using multiple rotary files to achieve the same final shape. Conveniently, the WaveOne concept is system-based. Each WaveOne file has matching paper points, gutta percha master cones, carrier-based obturators and carrier-free GuttaCore obturators. Importantly, the WaveOne single-file technique is the convergence of a unique file design, advancements in NiTi alloy, and a novel reciprocating movement.
Strategically, only 1 file is generally utilized to fully shape virtually any given canal. However, there are 3 WaveOne files available to effectively address a wide range of endodontic anatomy commonly encountered in everyday practice. The 3 WaveOne instruments are termed Small
(yellow 21/06), Primary
(red 25/08), and Large
(black 40/08). The Small 21/06 file has a fixed taper of 6% over its active portion. The Primary 25/08 and the Large 40/08 WaveOne files have fixed tapers of 8% from D1-D3, whereas from D4-D16, they have a unique progressively decreasing percentage tapered design.
