Wedges

Featuring NiTi super-elasticity, the V-Ring provides superior tooth separation and retention, but is more compact than other retainer rings.
The image beside shows the contact before, and after 3 minutes with the V-Ring in place. The separation achieved was 60-80µ. Better contacts, easier to use.

The V-Ring is the only retainer ring with V shaped tines ( patent-pending ) This unique V-shaped space accommodates the wedge, rather than getting in its way.

Unlike other rings, the V-Ring does not collapse into wide cavities, and locates the sectional matrix without deforming it, for a more consistent, natural, anatomical shaped restoration. This drastically reduces finishing, and also alows you to work quickly and easily in almost any situation, making it by far the most versatile sectional matrix system on the market.

The Tab-Matrix is the thinnest and the most anatomically accurate matrix available. Flat matrices produce flat side restorations and leave ledges and ridges, so if you want to replicate the original proximal-form quickly and accurately, use these tab-matrices to reduce your finishing and give your patient a restoration you'd want in your own mouth.

The most obvious novel feature of the Tab-Matrix is the Tab which overcomes the frustration caused by the difficulty of placement of such a small part. The Tab acts as a 'handle' that can be bent mesially to enable the Tab-Matrix to be easily gripped with any kind of tweezers.
Tab-Matrices are available in 3 different sizes (4,5mm, 5,5mm, 6,5mm)

Tapered tip and curved profile guides the wedge gently through, without piercing the gingivae and without promoting bleeding! Kind to gingivae. The wedge's lateral wings compress as they slip through the inter proximal space, and flare again upon exit, providing easy placement and broad, adaptive, symmetric sealing of the matrix gingival margin.
Less flash, less finishing. better restoration! The Wave Wedge's central concavity ensures that it 'clicks' into place to ensure optimum sealing and locating to accommodate the V-Ring.

The hollow V-shape underneath provides a space for the gingival tissue.

The fine wings tend to draw the wedge down into the inter proximal space rather than rising up like most wedges. Need to re-position or add another wedge? Pin tweezers make it easy, and you dont have to start again because the wedge can be removed with the V Ring in place.

The small hole provided on the end of the wedge allows the patented TrioDent Pin Tweezers to lock on - for sure and safe placement and removal. Much easier, faster and more controllable than any other wedges!

These superior Pin Tweezers incorporate a pin in the tip which securely locks onto matrices and wedges during placement and removal, eliminating fumbling and dropping of these small components, and allowing you and your assistant to work faster, and reduce the risk of patient inhalation. The tip also features a ball-burnisher for improved contacts and single instrument conveniance.

Hold the Tab-Matrix by gripping the tab with the Pin-Tweezers. Then fold the tab towards you. This enables you to easily slide the matrix into the embrasure in an apical direction .

Squeeze the wings a little to increase the curvature of the matrix as this provides more room for the V-Ring tines later.

Introduce the matrix into the embrasure, ensuring  that the matrix is in the gingival crevice adjacent to the tooth you are restoring.

If the cavity is an MO then the matrix needs to be turned around but the tab still needs to be folded towards you.

Using the tips of the tweezers fold the tab over so that it sits above the marginal ridge of the neighbouring tooth.
This is unnecessary for an MO cavity.

Keep your fore-finger on the tab to prevent it moving. Ask your assistant to load an appropriately sized Wave-Wedge or V-Wedge into the Pin-Tweezers. They are colour coded to make it easy. Insert the wedge and push it in firmly. Remember, you are not wedging to separate the teeth ( the V Ring will do this at the next stage ) so the wedges are less invasive and much easier to insert than wooden wedges for example. You should now have a good seal around the bottom of the cavity, with no colored wedge visible inside. If required, you can insert a larger or an additional wedge. Take your time, and drastically reduce flash and finishing.

Ask your assistant to pass you the V Ring already on the forceps with the lock on.
DO NOT RUSH THIS PART!
Using a finger-rest to steady the forceps, slowly, as if landing a helicopter, move the V-Ring into position so that it straddles the wedge. Make sure that it is in direct contact with the wedge and will not go any further in an apical direction.
Make sure the forceps locking mechanism is released and slowly allow the V-Ring to close. It usually is a good idea to trap the tab with a finger or the side of the mirror-head against the marginal ridge of the neighbouring tooth to prevent displacement at the last second. ( Note, if you lack experience with landing helicopters, dont worry, just go slow anyway!)

The image below shows a close-up of the V-Ring on backwards. The tip of a purple Wave-Wedge is protruding through the V-shaped slot in the V-Ring.

The V-Ring system allows a second wedge to be easily placed from the other side as shown below. The second wedge can be fitted underneath the first wedge as shown below.
This feature gives the V-Ring system unrivalled flexibility and enables the dentist to easily adjust the wedging without starting all over.
