Easy - Safe - Time saving

Inspired to find a simpler and safer way to successfully prepare a root canal, whilst complying with the highest quality requirements, VDW developed RECIPROC®. Forget about time-consuming instrument changes and work steps! It’s possible to prepare even complex root canals with predictable results using just one instrument.

RECIPROC® instruments are designed to be used as a single instrument. That means that one instrument only is required to prepare a root canal. The shape obtained by the RECIPROC® instrument enables effective irrigation and obturation with both cold and warm techniques.

The new RECIPROC®blue file generation combines the ease of the original RECIPROC® one file endo concept with enhanced safety in root canal preparation for patients. An innovative heat treatment makes RECIPROC® blue particularly flexible to ensure a smoother and safer progression in the canal.

Dentists about RECIPROC®

„RECIPROC® and the VDW.GOLD®RECIPROC® motor are by far the best system and I wouldn't choose any other. It's easy and quick to use, and the automatic stop at the apex is safety at its best. RECIPROC® is well worth the money!

Dr. Izzettin Oezkaynak, Biel/Bienne, Switzerland

„As far as I'm concerned, it's the quickest and most accurate way of preparing and filling root canals. The concept is simple and logical. Difficult cases are easier and safer to treat than previously. Working with RECIPROC® is reassuring!“

Dr. Ruckenstuhl, Graz, Austria

"The instruments are much easier for me to handle: they are sterile when delivered and are only used once. That means they do not have to be cleaned, sorted into boxes and sterilised, and there is no need to keep a record of how often an instrument has already been used. Endo without RECIPROC® – fortunately that's a thing of the past!"

RECIPROC® Highlights

The reciprocating movement

The reciprocating movement

RECIPROC® – Root canal preparation with an innovative twist!

The RECIPROC® instrument alternates between clockwise and counterclockwise rotation. Due to the fact that the rotation in the cutting direction is larger than the reverse rotation, the instrument advances towards the apex. The reciprocating movement relieves stress on the instrument and, therefore, reduces the risk of cyclic fatigue caused by tension and compression (De-Deus et al. 2010; Varela-Patiño et al. 2010). At the same time, reciprocation ensures that the instrument stays centred in the canal.

The reciprocating movement allows root canals to be prepared with one single instrument.

A specific instrument design

A specific instrument design

  • An innovative instrument for a complete preparation:
    RECIPROC® instruments have been designed with diameters and tapers which give an optimal apical preparation in most cases according to the canal anatomy, and using just one instrument.
  • A regressive taper for a preparation with no unnecessary loss of tooth substance:
    RECIPROC® instruments are slimmer at the end of the working part than most conical NiTi instruments of comparable diameter, preventing unnecessary loss of tooth substance in the coronal part.
  • Proven cleaning ability:
    RECIPROC® cleans even severely curved canals (Bürklein et al. 2012).
  • Suitable for preparation of severely curved and narrow canals:
    Also severely curved and narrow canals can be prepared with one RECIPROC® instrument.

Glide Path Management

There are two ways of using RECIPROC®:
with and without initial hand filing to create a glide path.

The Standard Up Until Now: Initial Hand Filing to Create a Glide Path before the Use of Rotary Instruments.

With continuous rotary NiTi systems it is necessary to create a glide path in order to minimise the risk of fracture. During the use of a rotary instrument, the tip of the instrument may bind in the canal. For this reason, it is necessary to create an initial glide path, or a minimal canal enlargement, before using continuous rotary instruments.

Just as with any continuous rotary NiTi system, it is possible to use the RECIPROC® reciprocating instrument after creating an initial glide path with hand instruments (e.g. C-PILOT® file) to an ISO size 10 or 15. However, RECIPROC® and the reciprocating movement has opened up a new possibility: using RECIPROC® without initial hand filing in the majority of cases.

A Paradigm Shift in Endodontics: Using RECIPROC® without Initial Hand Filing to Create a Glide Path in the Majority of Cases. 

A Paradigm Shift in Endodontics

A Paradigm Shift in Endodontics: Using RECIPROC® without Initial Hand Filing to Create a Glide Path in the Majority of Cases. 

"The concept of using a shaping instrument without first creating a glide path with hand or mechanical glide path instruments is a completely new way of thinking, a paradigm shift. It goes against the current teaching standard which requires the creation of a glide path prior to using a rotary instrument to prevent it binding in the root canal.

In reciprocation, clockwise and counterclockwise angles determine the amplitude of reciprocation, the right and left rotations. These angles, stored in the motor, are significantly lower than the angles at which the RECIPROC® instrument would usually fracture (if bound). When a reciprocating instrument binds in the canal, it will not fracture because it will never rotate past its specific angle of fracture. Therefore, the creation of a glide path to minimise binding is not required for the RECIPROC® instruments.

I want to introduce the notion of the path of least resistance. The reciprocation technique’s centring ability together with the design of the RECIPROC® instrument and its increased cutting ability allows the RECIPROC® instrument to follow the existing and natural path of least resistance, which is the root canal. I want to take advantage of the presence of that natural path with the RECIPROC® instrument in order to eliminate initial hand filing for the creation of a glide path in the majority of cases. This is not only time-saving but also particularly convenient in teeth with limited access. Additionally, errors associated with the use of hand filing prior to using mechanically driven instruments can be avoided.

Retreatment Step by Step

Retreatment Step by Step

Gutta-percha filling material can be removed from the root canal with the RECIPROC® R25.

  • Remove the bulk of the gutta-percha in the coronal third of the canal with an appropriate instrument e.g. Gates Glidden drill or an ultrasonic instrument such as VDW.ULTRA®.
  • Use a drop of solvent (e.g. eucalyptus oil) as required.
  • Use R25 as described until working length has been reached. If resistance is encountered, do not apply pressure. Remove the instrument from the canal, replace a drop of solvent and try again.
  • Use a brushing motion against lateral walls to remove residual obturation material.
  • After reaching working length with R25, use R40 or R50 for an increased apical enlargement, as necessary. 

Retreatment of Carrier-Based Obturators

Retreatment of Carrier-Based Obturators

Proceed as described in points 1. to 5. above. The carrier may be removed in one piece during the use of the RECIPROC® instrument; otherwise, it will be removed in small pieces with the gutta-percha.
