Safer, faster, more flexible

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

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

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

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
![Page 16: A Clinician’s Guide to Root Canal Therapy](https://reader035.vdocuments.mx/reader035/viewer/2022062301/568158d6550346895dc61fa8/html5/thumbnails/16.jpg)
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)

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

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
