twisted files
TWISTED FILES
  • Safer, faster, more flexible
hybridized passive crown down instrumentation technique
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
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
Establishing a Glide Path
  • Scouting files
  • Working length
  • Apical glide path (#20 file)
  • Recapitulation
glidepath into apical third
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
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 s eat
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
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
SENIA’S WORKING WIDTH
  • Apical preps approaching size 100
working width

  • Round instruments cleaning oval canals
