Triodent
The key to the V3 sectional matrix system is the Ni-Ti V3 Ring, which uses optimal separation force to achieve predictably tight contacts. The V-shaped tines straddle the Wave-Wedge, and the tine’s broad shape prevents the ring from collapsing into large cavities. The V3 matrices, with their rolled marginal ridge and S-shaped vertical contour, recreate the proximal anatomy, so there is less finishing. The wedge provides an excellent seal on the gingival margin.
