What term describes a metal band placed around a prepared tooth to recreate the proximal wall during a restoration?

• A. Matrix Band
• B. Matrix Holder
• C. Rubber Dam
• D. Amalgam Carrier

Answer: (A)

Matrix Band In a restoration, especially Class II cases, a matrix band is the thin metal loop wrapped around the prepared tooth to recreate the missing proximal wall. It acts as a temporary wall and contour guide so the restorative material can be placed against it and form a proper contact with the adjacent tooth. The band is typically secured with a matrix retainer (matrix holder) and often a wedge is used to adapt it tightly against the tooth. Rubber dam is for isolation, and an amalgam carrier is simply used to place material; neither creates the proximal wall.
