Triodent V3 Sectional Matrix System

Because I practice inside of a dental laboratory, I typically only do direct restorations when they are adjacent to other indirect restorations I am placing. I was introduced to this sectional matrix system while I was testing BruxZir® inlays and found myself doing only inlay preps for a month. While I was able to rationalize that it was OK when I nicked an adjacent tooth while dropping the proximal box and extending it buccolingually, a fellow dentist told me about the WedgeGuard interproximal tooth shield, which is an integral part of the V3 Matrix. WedgeGuard is the standard Wave-Wedge interproximal wedge with a metal protector attached to it. Place the WedgeGuard between the teeth and prep the tooth safely with the metal protector in place. After you finish the prep, you simply grab the metal protector and pull it out with the wedge still in place. Then you place your matrix, place the V3 Ring, and place and cure the composite. Genius!
