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.
Claims8
A device for making fillings in posterior teeth, comprising an elastic band member having a circumferentially complete contour including two first sections arranged to surround proximal surfaces of a tooth and connected by two second sections arranged to surround a buccal surface and a lingual surface of the tooth, respectively;
- a wedge-shaped tightening member arranged to be inserted between said band member and the tooth inside said band member, so that said band member is tightened and firmly abuts against the tooth and is retained on the latter so as to form a matrix for filling, said wedge-shaped tightening member being of one piece with said band member;
- and means for connecting said wedge-shaped tightening member with said band member.
A matrix device for making fillings in posterior teeth, comprising an elastic band member having a circumferentially complete contour including two first sections arranged to surround proximal surfaces of a tooth and connected by two second sections arranged to surround a buccal surface and a lingual surface of the tooth, respectively, said band having at least one projection having a concave wall arranged to be engaged by a tool so as to place said band member onto a tooth;
- and a wedge-shaped tightening member arranged to be inserted between said band member and the tooth inside said band member, so that said band member is tightened and firmly abuts against the tooth and is retained on the latter so as to form a matrix for filling.
