The system allows for maintaining or recreating close interproximal contacts between teeth following restoration. A matrix band is provided which retains in place a contact matrix that upon completion of the restoration is tightly bound to the filling matrix deposited into the cavity, and thus maintains or recreates a tight contact with adjacent teeth. The system provides an improved system for use in dental surgery, and by implementing the kit provided clinicians are able to provide enhanced results following restoration with a minimum of effort.
