I have always been drawn to new technology. When analyzing the WaveOne file, it is clear that a lot of science went into its development. The concept and design behind the file system is built around a conservative shaping approach. The file system allows me to establish deep shape in the apical third of the root canal system while maintaining a conservative preparation in the middle and coronal third.
What sets the files apart from other endo files you’ve used?
The main distinguishing feature that separates WaveOne technology from other engine driven instruments is reciprocation. While it is not a new concept—engine driven reciprocation was first introduced in 1969—the unique feature to WaveOne is its asymmetric envelope of motion that mimics the “Balanced Forces” hand shaping technique, which has been shown to minimize canal transportation during shaping due to its ability to keep the instrument more centered in the canal. The WaveOne system is the first engine driven system that accurately reproduces the Balanced Forces concept.
Do they work best for one type of case?
WaveOne files are suited for any and all cases. I have used these files on single canal anterior teeth as well as complex, curved, multi-rooted molars. I find these files to perform very efficiently while providing great shapes regardless of tooth or canal type.
Has using the files changed your technique for shaping canals?
No. I have a very regimented canal shaping technique that is anchored by orifice opening, glide path establishment and glide path maintenance. The advantage of the WaveOne system is that I don’t have to change my technique.
What has been the biggest benefit?
The biggest benefit of WaveOne in my hands lies with the Primary file in smaller canals (a size 25 progressive 8% (.08) tapered file). My personal philosophy, based on my interpretation of the literature, dictates that the final shape of any canal should be prepared to no less than ISO size 25 with a minimum taper of 6% (.06) (exceptions will occur). The rationale behind this philosophy is based solely upon the ability to deliver the irrigant to within 1 mm of the working length.
The progressive shape of the WaveOne Primary file allows me to introduce all irrigation products to the exact length needed to establish the most predictable outcome while maintaining a conservative preparation and keeping the apical foramen as small as reasonably allowable.
