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

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 100

Round instruments cleaning oval canals
