摘要 A method and apparatus for use in restoration procedures for teeth. The apparatus includes a matrix having a facial portion extending between a pair of wings. The facial portion has an anatomically contoured inner surface which extends between a pair of corners. The wings of the matrix are affixed together by an adhesive strip.
