No. The WedgeGuard is for protecting the adjacent tooth from unintentional damage. If you use it as a matrix it will create an overhang. After removing the metal shield, the wedge can then be used as a wedge, retaining all the qualities of a Triodent Wave-Wedge.

You can improve vision and access by cutting away part of the guard, for example with a high-speed diamond bur.

If the contact point is too tight to get the WedgeGuard through, cut through the occlusal enamel into the carious lesion to weaken the marginal ridge. Once the marginal ridge is fractured off, it is easy to push the WedgeGuard through.

If there is no room to slide the matrix directly in between the wedge and the cavity, slide the wedge out partially, then place the matrix, then push the wedge back in. Use a finger to trap the matrix against the side of the tooth while doing this to ensure it does not move.

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. The WedgeGuard will separate the teeth just slightly but that is not its function. Triodent gives the main job of separation to the V3 Ring or V-Ring, leaving the WedgeGuard free to fulfill its role firstly as an interproximal guard and then to provide an excellent marginal seal when the guard is removed and replaced with a standard matrix.

Yes, you can. The wedge used in the WedgeGuard retains all the qualities of the Wave-Wedge.
