Establishing approximal contacts in Class 2 composite resin restorations.

Ensuring adequate approximal contacts when performing class 2 composite resin restorations is a significant challenge for the dentist. Fabrication of custom composite cylinders for placement into prepared cavity preparations enables the dentist to wedge the matrix band firmly against adjacent teeth, as well as eliminating the curing contraction variable that occurs when composite restorations are placed. Thus, predictable approximal contacts are obtained when class 2 composite restorations are completed.
