Q. What can I do if there is a gap at the bottom of the axial corner of the box with the Wave-Wedge in place?
A. The Wave-Wedge, because of its unique central concavity, has exceptional 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.
Q. The point of the Wave-Wedge is quite sharp. Will it cut the gingival papillae?
A. The Wave-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 Wave-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.
Q. Apart from the adaptive sealing qualities, what are the reasons for the central concavity in the Wave-Wedge?
A. The central concavity is actually the second feature in the Wave-Wedge’s remarkable bag of tricks. First, come the fine lateral wings at the point of the wedge. These compress easily as the wedge enters the embrasure, and then expand again as the wedge exits on the other side of the tooth. This is when the concavity comes into its own, effectively locking the wedge into place at its central point, and wrapping around the matrix at the gingival margin for a broad, adaptive and symmetric seal. It is also then in the best spot for positioning the V3 Ring.
Q. What is the hole for at the end of the Wave-Wedge?
A. While other wedges are easily dropped, Wave-Wedges and Triodent’s V-Wedges are secure in Triodent’s Pin-Tweezers which, as the name implies, have a pin at 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.
Q. Do Wave-Wedges separate the teeth?
A. Unlike the Wave-Wedge and Triodent’s V-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 Wave-Wedge free in the role of holding the matrix and sealing the gingival margin.
