This matrix system works very well for direct composite restorations, specifically for posterior teeth. It’s useful for virtually all multi-surface restorations in posterior teeth.

What’s good about it

I particularly like this system for large composite restorations in the posterior region because the matrix system has multiple curvatures which mimic natural tooth form. It creates a more anatomical form, saves time in shaping, trimming and polishing, and improves the function of the completed restoration. When dealing with a large cavity, it creates a more stable restoration than other matrix systems. I’ve found it particularly useful when dealing with older clients who have very broken-down teeth and are not in a position to afford extensive indirect restorations. This is a significant and increasing section of my client base.

Large posterior composite restorations can be hard work and a serious challenge to build natural tooth form in a time-effective manner. The SuperMat system goes a long way toward resolving that problem.

What’s not so good

It is relatively expensive compared to other matrix systems. I’ve had some slight difficulties with the ratcheting system in a couple of cases. In some situations where there isn’t good stability, it can be hard to get it tight enough on the main tooth structure to complete the restoration easily.
