WaveOne NiTi file from Dentsply Maillefer is a single-use, single-file system to shape the root canal completely from start to finish. Shaping the root canal to a continuously tapering funnel shape not only fulfills the biological requirements for adequate irrigation to clean the root canal system of all bacteria, bacterial by-products and pulp tissue but also provides the perfect shape for three dimensional obturation with gutta percha. The specially designed NiTi files work in a similar but reverse ‘balanced force’ action using a preprogrammed motor to move the files in a back and forth ‘reciprocal action’. The files are manufactured with M-Wire technology improving strength and resistance to cyclic fatigue by up to nearly four times in comparison with other brands of rotary NiTi files. It is manufactured based on M-Wire technology improving strength and resistance to cyclic fatigue by up to nearly four times.
There are three files in the WaveOne single-file reciprocating system which are available in lengths of 21, 25 and 31mm:
- The WaveOne Small file is used in fine canals. The tip size is ISO 21 with a continuous taper of 6%.
- The WaveOne Primary file is used in the majority of canals. The tip size is ISO 25 with an apical taper of 8% that reduces towards the coronal end.
- The WaveOne Large file is used in large canals. The tip size is ISO 40 with an apical taper of 8% that reduces towards the coronal end.
WaveOne technique involves the following stages:
- Straightline access, accepted protocol
- WaveOne file selection
- Single-file shaping
- Copious irrigation with 5% NaOCl and EDTA before,during and after single-file shaping.
The plastic color coding in the handle deforms if sterilized.
The advantages of WaveOne files includes:
- Improve flexibility.
- Conserve remaining dentin in the coronal two-thirds of the finished preparation.
- File safely progress through virtually any secured canal.
The WaveOne Gold system is a single-file and single-use technique. There are 4 WaveOne Gold files available in various lengths. This advancement provides excellent safety, effortless efficiency, and super simplicity, beyond the orginal WaveOne system. The 4 files are termed Small (yellow 20/07), Primary (red 25/07), Medium (green 35/06), and Large (black 45/05).
