Inspired to find a simpler and safer way to successfully prepare a root canal, while complying with the highest quality requirements, VOW has developed Reciproc, which is now sold exclusively in the UK by Quality Endodontic Distributors (QED).
In a reciprocating movement, Reciproc prepares root canals easily, safely and quickly. It’s even possible to prepare canals with difficult anatomies with predictable results using just one instrument.
At the UK launch of this new system, top endodontists enjoyed the renowned QED hosting, with dinner in London the night before a full and detailed product launch seminar, including clinical hands-on experience the next day. The hands-on module was ideal for dentists to try out and test the product and its claims under no pressure of a live patient or time constraints.

New concept of root canal preparation
There is a choice of three Reciproc instrument sizes according to the type of root canal. Instruments are delivered ready-to-use, pre-sterilised in blister packaging and should be discarded after use.
The system works clue to reciprocating movement that allows root canals to be prepared with a single instrument.
A specific instrument design of ISO sizes and tapers give an optimal result for a complete preparation. A regressive taper is designed into the system for a preparation with no unnecessary loss of tooth substance. This enables preparation of even severely curved and narrow canals, with no initial hand filing in the majority of cases.

Ease of use
With only one instrument dentists can prepare a root canal to a greater taper. There is no need to change instruments or to establish a glide path in the majority of cases, so the system is simplified and therefore easy to learn.
It is safe too because the risk of instrument fracture is minimised due to precise reciprocation settings in the specially developed motor (VDW Silver).
It is safer for the patient and operator as all instruments come pre-sterilised and are recommended for single-use. This reduces the likelihood of procedural errors and gives greater resistance to cyclic fatigue. But to make the product even safer, VDW has designed the nickel titanium M-Wire technology.
The whole system is time-saving through design. There are less working steps and no cleaning and sterilisation of instruments is required, which will dramatically reduce working time in the modern busy practice.
Ghassan Yared explains it best in his published paper on reciprocating action in endodontic files systems for root canal preparation. He says that reciprocating action is a paradigm shift and canal preparation is accomplished using only one specifically designed nickel titanium engine­driven instrument used in reciprocation and without prior hand filing to expand the canal. He says there is no need to use multiple-sized files to enlarge the canal. One file will suffice (but with few but some exceptions).
He adds that a glide path is no longer a pre-requisite with this new concept and that the new product introduced the notion of 'path of least resistance', where the reciprocating file follows this path, which happens la be the root canal.

Three instruments and motor
The motor is battery operated and rechargeable and can be used while the battery is charging. The instruments are used at 10 cycles of reciprocation per second, which is around 300 rpm. The motor is programmed with the angles of reciprocation and speed for the three instruments in the range.
The three instruments are for narrow, medium and large canals; all kept very simple for faster, easier and hassle-free endodontics. The instruments come in three working lengths too.
The new endo motor can be used for innovative reciprocating instruments as well as conventional rotary NiTi systems like Mtwo.

Safety
At the product launch it was stressed and proven that reciprocating action with nickel titanium files reduces stress on the instrument and will reduce the chances of fracture.
Delegates were left asking the question: will reciprocating action take over from rotary in the future of root canal preparation?
