V3/V4 Ring and Matrix system

17 February 2016

Whilst many readers will be familiar with this system already, those that are not will find it uniquely placed to deliver quick & reliable, tight convex contact points when compared to straight sided bands such as the Tofflemire or Automatrix systems.

Whilst those systems are excellent for four or more surface fillings, the V3 ring and matrix system is extremely convenient for interproximal restorations. Simultaneous use of two bands can also be useful for MOD style restorations.

There are three notable components to this system, which was originally designed by a dentist (and it shows):

1. Clamp (or ring)

The V3 system has a more recent version, the V4 ring – with translucent clamp sides. 

The V3/V4 clamp is great for a few reasons – it has anatomical two pronged sides that sit either side of the interdental papillae and allow easy seating of the interproximal wedge. The design also keeps the matrix band tight against the gingival margin of the cavity and pushes the matrix slightly outwards to meet the neighbouring tooth.

2. Matrix

Stainless steel and Teflon coated types are available. I choose to use the Teflon coated versions which brought an end to using artery forceps and pulling hard to remove matrices after a successful contact point was built. These are arguably the best part of the system, as the manufacturer has managed to create a convex, kidney shaped matrix that allows truly anatomical restorations. It is rare that an excellent contact point isn’t established on the very first go, even without burnishing. 

They come in different heights, normal, medium and deep. The deep band even has a small kink designed to replicate the DEJ anatomy. 

3. Wedge

These are also uniquely anatomical, with a triangular, curved design that sits above the papilla and follows the curvature of the gingiva. It slides easily under the clamp.

In order to use the system a proprietory set of clamp forceps is recommended. Whilst a pair of proprietary tweezers can be bought which lock into the deliberately placed circular grab points on the matrixes and the wedges, I rarely end up using them.

The only downside to the system is its inability to cater for four or more surface restorations which need a band entirely encircling the tooth.

In summary, whilst not the cheapest, the incredibly well thought out design of this system makes it one I can’t do without.
