2.  ProFile Rotary Files  ProFile Vortex Files, Vortex Blue and Vortex Orifice openers  GT and GT series X Files  ProTaper and Protaper next  Wave one

3.  EndoSequence, Brasseler  Quantec K3 files, SybronEndo  Twisted File, SybronEndo  LightSpeed and LigthSpeed LSX

4.  Edgefile X1 for Waveone users  Edgefile X3 for Protaper users  Edgefile X5 for GT and GTX users  EdgefileX7 for Vortex, Profile,K3 Twisted file and EndoSequence users

6.  Safer, faster, more flexible

7.  Hybridized refers to using multiple systems  Passive means having a gentle touch that follows established guide paths  Crown down starts at coronal orifice and works to apical terminus  Advantages

8.  Orifice Widening  Glide path into apical third of the canal  Coronal Preflare  Glide path to apical foramen  Extension of access into apical terminus of preparation  Preparation of the apical seat

14.  Scouting files  Working length  Apical glide path (#20 file)  Recapitulation

15.  After orifice widening  Niti instruments require a glide path  In this technique it must extend beyond the 17 mm depth of the GT files  08 and 10 file into apical one third using lubricant and irrigation

16.  All Niti instruments require a glide path  Preflare reduces cyclic fatigue and taper lock  Allows debris removal early to prevent apical extrusion of infected material  Select job specific instrument (GT #20 17mm.12.10.08.06)

23.  Everything preceding this step is designed to promote complete control of this most critical step  This is the BIOLOGICAL ZONE  Hybridization is key

24.  Apex Locater and then 08 file to radiographic apex (seat is 1mm short of radiographic apex)  Flexible files, Balanced force technique  Narrow vs wide apical preparation

26.  Apical preps approaching size 100

27.  Round instruments cleaning oval canals
