EDGE ENDO • 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
TWISTED FILES • Safer, faster, more flexible
Hybridized Passive Crown Down Instrumentation Technique • 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
HPCD Technique • 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
Establishing a Glide Path • Scouting files • Working length • Apical glide path (#20 file) • Recapitulation
Glidepath into Apical Third • 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
Coronal Preflare • 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)
Preparation of the Apical Seat • Everything preceding this step is designed to promote complete control of this most critical step • This is the BIOLOGICAL ZONE • Hybridization is key
The Apical Seat • 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
SENIA’S WORKING WIDTH • Apical preps approaching size 100
WORKING WIDTH • Round instruments cleaning oval canals
