ABSTRACT:
A device for making filling in posterior teeth has an elastic band member with two first portions and two second portions, and a wedge-shaped member insertable into the interior of the band member between the latter and a tooth so as to tighten the band member which is thereby retained on and abuts against a lateral surface of the tooth. The wedge-shaped member may be connected and formed of one piece with the band member. The band member may have a profiled lateral portion which is bendable and can abuts against the occlusal surface of the filling so as to compress and condense the filling material and to provide a required shape of the occlusal surface.
