Here are some examples of how the Sure Matrix can be used:
Here the Sure Matrix is used conventionally.
Using flowable, the Tight Contact Tabs on the Sure Matrix have been pulled and temporarily bonded to an adjacent tooth to create a broader contact.
This wide cavity is problematic because the separating ring can collapse the matrix inwards. In this example, the Separator Wedge takes care of the separation, the Tight Contact Tab is pulled and secured to the adjacent tooth, and the Tight Contact Tabs are held in place by flowable composite.
This process virtually eliminates flash as the matrix is intimately in contact with all of the cavity margins.
Here is the same case showing the dimple on the matrix where the matrix touches the adjacent tooth.
Note how we can select where we want the contact point by bonding the Tight Contact Tab at the anatomically correct location (slightly buccally for the upper premolar).

“I was fortunate to be given some trial samples of the ‘Sure Matrix’. They are very nicely shaped and contoured matrix bands. Using the flowable means not having to use a tension ring interproximally which is a massive bonus. Better visibility and easier to position the curing light. The ability to tack the band buccally and palatally means you can form a predictable contour and minimise excess flashings. I was skeptical about the contact point being adequate, but with good wedging and proper creation of the dimple when securing the band in position, it is easy to create a good contact point that flosses how it should. I will be using the ‘Sure Matrix’ in preference to my other systems from now on.”
“The Sure Matrix system leads to an ideal curvature of the proximal surface, both buccolingually and vertically towards the occlusal surface. It’s really nice to be able to leave the proximal surface alone during finishing.”
Pulling more firmly gives you a broad contact point. You can pull too hard and create an inverted dimple at the contact point. It is best to examine the matrix at the contact point and assess the size of the dimple and adjust the pulling force accordingly.
The Separator Wedge (part of the Sure Matrix system) generates more separating force than many rings so you will get tight contacts if the Separator Wedge is a tight fit.
If you use a separator ring, you can still use a Separator Wedge but do not use too much force when inserting it otherwise this may result in a contact that is too tight.
Some of our dentists routinely paint some dental bond on the adjacent tooth (without etching) before placing the flowable to assure good bonding.
Use enough flowable to cover most of the holes in the tab.
If there is a fresh composite filling on the adjacent tooth the bond can be too strong. See FAQ below.
Flowable can be too strong when bonded to freshly cured composite and this can become an issue if the adjacent tooth has just been restored.
One simple option is to skip the idea of bonding the tab to the adjacent newly restored tooth and use a separating ring and your regular sectional matrix procedure in this case. You can still use the Sure Matrix and Separator Wedge.
The other solution is to apply an air-thinned layer of KY Jelly then apply the flowable over the new occlusal restoration.
This creates a bond that is strong enough to hold and also pulls off in one piece when removing the matrix. We have tested glycerine, it did not work as well as KY Jelly and is not recommended.
