What would you recommend to avoid damaging adjacent teeth during the preparation of Class II cavity preps?

One new product that works well is called WedgeGuard (Triodent Corp.). It is composed of a metal guard attached to a plastic wedge that is inserted interproximally before preparation. It was found by our Clinical Consultants to protect adjacent teeth and to save time during preparation. The guard/wedge is inserted with special forceps. After preparation, the guard is removed, but the wedge remains. The product is recommended for Class II, III, crown, veneer, and tunnel preparations.
