ABSTRACT:
A matrix band for front teeth consists of a plastic band having two parts which extend away from each other as a preferably obtuse angle. In one embodiment, a transition area between the two parts is elastically extensible. In another embodiment, the transition area is plastically extensible. On each side of the transition area there is a substantially inextensible part. A matrix retainer for a matrix band has a tightening element which has a through channel dimensioned for continuous frictional engagement with two substantially inextensible portions of the matrix band which are movable face-to-face through the channel. The matrix retainer also has a locking element for fixation of the two inextensible portions relative to the tightening element.
