E3 Conserve File

Prepare - Preserve - Restore

Designed with cutting edge technology that offers real world application. Minimally Invasive by design, with the strength and flexibility like no other, E3 Conserve files are manufactured in the USA to the strictest guidelines to insure excellent consistency and performance, time after time.

Conserve More Dentin for Longer Lasting Restorations

The variable decreasing taper of the E3 Conserve preserves more pericervical dentin when compared to other variable increasing taper files like the ProTaper Gold®. Smaller tapering in the mid and upper portion of the E3 Conserve file results in unmatched flexibility while providing better initial access and conservative restorative options.

No Change to Your Current Technique

The E3 Conserve file system has been designed with multiple tapers that ensure flexibility and cut dentin in specific canal zones, while utilizing a .8 MFD for maximum pericervical dentin conservation, reducing the potential for over-preparation. E3 Conserve files are available in comparable sizes, lengths and tapers to the Dentsply® ProTaper Gold® file system, and Edge Endo® Edge Taper™ file system. They require no change to current protocol or technique and offer the same predictable results.

Creating Initial Access

1If removing a PFM or Zirconia crown, begin initial access by using the Great White or Great White Z.
2Locate the orifices and create straight-line access using EndoGuide®.
3Once the canals are located, the walls are made smooth and parallel using the non-end cutting Endo Safe-End® bur to complete the access.

Minimally Invasive Endo Made Easy

1Scout the coronal half of the canal with a pre-bent size 8 file, followed by size 10 and, if needed, size 15
2Use the SX file in a brushing motion on the outstroke to enlarge the coronal portion of the canal
3Confirm working length with an electronic apex locator and create a glide path using size 8 and 10 hand files.
4Use the shaping files (S1 and S2 if required in narrow or more curved canals) with a brushing motion on the outstroke to working length.
5Use the finishing files (F1-F4) with an 'in and out' action (not brushing)
6Always make sure to work in a wet field with NaOCl and use intra-canal lubricant when manually scouting canals
7Always irrigate and recapitulate with a size 10 hand file after each pass of a rotary file
8Frequently clean and inspect the flutes of E3 Conserve files and discard if unwinding is seen

Recommended Settings

As with all new products, you must exercise caution until you become proficient in its use. Length determination is imperative to ensure proper instrumentation using any rotary or hand instrument.

  1. A torque controlled handpiece is required for rotary file use.
  2. Operate the hand piece at a speed of 400 RPM (Revolutions Per Minute).
File Speed (rpm) Torque (N/cm)
SX, S1, S2 400 2
F1 400 2
F2, F3, F4 400 3
