  • Patent number: 6257885
    Abstract: There is provided an instrument which carries a tool (52) that is transparent to light used to harden or cure a composite material. A matrix band (30) is placed around a molar or premolar and the composite material is placed on the tooth inwardly of the matrix band. The tool has a shaping surface (53) that has a shape and size corresponding to the mesio-occlusal shape or disto-occlusal shape of a corresponding molar or premolar of average shape and size. The tool (52) is pressed hard against the mesio or distal part of the matrix band (30) and against a neighboring tool whilst the tool (52) is, at the same time, pressed down in the composite material preferably so as to achieve contact with at least one of the cusps of the occlusal surface. The composite is light-hardened whilst the tool (52) is held in place.
