Fig. 21: A size 08 K-File in the M4 reciprocating handpiece was used to initiate the preparation of a reproducible micro glide path. Fig. 22: After the Size 08 K-File, a size 10 K-File was made ‘super loose’ to complete the preparation of the reproducible micro glide path. The rationale for this double file approach for glide path expansion was to enhance safety for the prepa- ration files that followed. The file tip of the WaveOne Gold Glider at D0 has a ISO 015 tip size with a 2 % taper, and the taper pro- gressively increase up to 6 % (D16; Fig. 29). The file has a semi-active tip and a parallelogram shaped cross-section. The WaveOne Gold Glider is manufac- tured using NiTi wire subjected to a post-manufac- turing thermal process, whereby a new phase-tran- sition point between martensite and austenite is identified to produce a file with super-elastic NiTi metal properties.15 This process gives the file a gold finish with enhanced flexibility and resistance to cyclic fatigue compared to conventional NiTi and M-wire alloys. The WaveOne Gold Glider was driven by the X-Smart motor, on the WaveOne setting. The file was taken up to working length in the already se- cured and expanded glide path and the glide path was further expanded by using a 4–8 backstroke brushing motions, until the file felt completely loose in the challenging canal systems. The WaveOne Gold Primary and Small files were selected for root canal preparation in this case. These Fig. 19 Fig. 20 Fig. 21 Fig. 22 28 roots 3 2017
