Sure MatrixTM – a better way to do Class II’s.

In dentistry it can be small changes that make the biggest difference.   The Sure Matrix™ with it’s unique long tab, anatomical shape and exceptionally thin width makes it a first class product.   

The real benefits are realised when you combine Blue Bond (a light cured removable bond) to create reliable tight contacts by attaching the tab of the matrix to the neighbouring tooth.  Blue Bond is ideal for naturally positioning the Sure Matrix™ for smooth margins without ledges. The extra security of having the band fixed in place makes the Sure Matrix™ easy to use in practice.   

A simple and versatile technique that creates tight contacts, natural anatomical shapes and predictable results all without the need for retainer rings.

Perfect for:

  • All class II restorations

  • Missing cusp restoration

  • Subgingival cases where it’s difficult to wedge

  • Cases where retainer rings distort the matrix

Sure Matrix Quick Step 1

How does the Sure Matrix work?

Step 1 – Prep & Wedge
After prepping the cavity, place the Sure MatrixTM, and wedge firmly with an appropriate wedge.  Rhondium’s Separator WedgesTM are specifically designed for this – however wooden wedges are applicable.   Allow the wedge to separate the teeth for a minute or so and  then  push the wedge into the interproximal space again. This ensures that the tooth separation is greater than the matrix foil thickness (35 microns).

Sure Matrix Quick Step 2

Step 2 – Create a tight contact with Blue Bond
Ensure the matrix is in the correct vertical position and the tab is directly above the desired contact point. Apply the Blue Bond or flowable resin around the long tab of the matrix. Place a dental probe into the small hole in the long tab and pull firmly towards the adjacent tooth. While still pulling, light-cure the Blue Bond. Pull harder to gain a broader contact point. A dimple should appear at the contact point demonstrating that the matrix is in contact with the adjacent contact point. This feature often alleviates the need to burnish. Some dentists light-cure their bonding agent at the same time as they cure the Blue Bond, saving a curing step. If the adjacent tooth has a ceramic crown are large amalgam, apply dental bond prior to the Blue Bond to aid adhesion.

Sure Matrix Quick Step 3

Step 3 – Create natural anatomy and margins with Blue Bond
If there are any gaps between the matrix wings and the cavity margins apply Blue Bond on the outside of the matrix. Use a flat plastic or probe to hold the matrix in the correct position and light-cure the Blue Bond.

What do dentists say about Sure Matrix™?

“I was fortunate to be given some trial samples of the ‘Sure Matrix’. They are very nicely shaped and contoured matrix bands. Using the blue bond 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.”

Dr. Graham Shaw, Jervois Dental

“Very easy to use and a lot quicker than a separator ring.  More control over embrasure shape.  Refreshingly simple and effective.”

“I found the sure matrix easier to use than a garrison ring.  The final contact area is tight and the marginal ridge had a good anatomical shape requiring less occlusal adjustment.”

Julia Tully, Lumino Darfield

“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.”

“Yet another excellent product from Rhondium – the Sure Matrix puts more predictability into ensuring a great outcome.”

John Thomson, Dentacare Ltd

Frequently asked questions

Some of our dentists routinely paint some dental bond on the adjacent tooth ( without etching)  before placing the blue bond to assure good bonding.

Use enough Blue Bond to cover most of the holes in the tab. The pulling force is discussed below.
If there is a fresh composite filling on the adjacent tooth the bond can be too strong. See FAQ below.

Blue Bond 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. And then apply the Blue Bond 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.

IF this happens, simply apply a bonding agent under the Blue Bonded tab, then a small amount of Blue Bond, and then pull on the tab again with a probe and light cure.

In these cases apply a bonding agent to the tooth/surface where the tab will sit, then add Blue Bond and light cure.
