"This new modification of the ring makes a lot of sense, and since some newer ring designs allow for better wedge placement, this new design offers two benefits – allows the placement of the wedge and the ring over top of it more easily, and the interproximal extension provides better separating force while adapting the matrix creating less flash and less work for the dentist in finishing class II composites. It is a definite step in the right direction."
