The V-Wedge has excellent sealing capacity on the matrix at the gingival margin. However, if there is a gap, you can wedge from both sides, thanks to the hollow underside which allows you to stack the wedges.

The V-Wedge's banana-shape design and tapered tip ensures the wedge is self-guiding, gliding through the embrasure without catching on the papillae. Moreover, because of the hollow underside, the papillae is accommodated and protected during the restoration. That is why the V-Wedge is ideally placed BEFORE cavity prep. Lubricating the tip of the wedge with a water-based lubricant or LA paste will also help it slide through without catching the rubber dam.

While other wedges are easily dropped, V-Wedges and Triodent's Wave-Wedges are secure in Triodent's Pin-Tweezers which, as the name implies, have a pin in the end that goes into the hole. Because of the cross-over action of the Pin-Tweezers, the wedges will not fall out when the tweezers are held in a neutral position, and are very secure when the tweezers are gripped.

Unlike the V-Wedge and Triodent's Wave-Wedge, most wedges have a conflict of function, needing to be hard enough to separate the teeth but soft and adaptive enough to provide a seal at the gingival margin. Triodent gives the job of separating the teeth to the V3 Ring or V-Ring, leaving the V-Wedge free in the role of holding the matrix and sealing the gingival margin.
