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





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

Apical preps approaching size
