Tools of the trade: Triodent V-ring Matrix System

matrix system

by Dr Owen Crombie, Crombie Dental Surgery, Hampton, VIC

I’ve used Triodent for years as my go-to matrix system. There are some very rare occasions when I’ll use a good old fashioned Tofflemire to build up the buccal and lingual, then recut the proximal portions and finish off with a V-matrix. However, the Triodent system works well for most large and small restorations, and I use it for almost all posterior restorations.

What’s good about it

This matrix system makes it much easier to get a nice contact between the teeth. The accompanying wedge system allows decent wedging of the gingival while the rings provide a margin of separation. It sits right down at the bottom of the tooth so it’s much easier to get the marginal ridge heights correct.

There is a new version, the V3, but I’m still using the same V-ring system I first purchased at the Australian Dental Congress 12 years ago. There are also other brands that have all sorts of bits and pieces but I find this system so effective, I can see no reason to change.

Of course, patients are unaware I’m using the V-ring system but they love the results. The outcome looks and feels fantastic and no food gets caught between their teeth.


What’s not so good

The greatest disadvantage is that it’s a little bit fiddly. If you are dealing with a large cusp replacement, you have to do the buccal and lingual first so that you’ve got a decent proximal box for the V-ring to work on.
