  • Patent number: 5890896
    Abstract: A single tooth handheld dental impression duplicating device and a method of using the device are disclosed. The device is designed to reproduce the occlusal surface anatomy of a particular tooth by making an impression, and after the setting of such material and having obtained the print of the tooth, use the device as a finishing mold for the restorative material. The device comprises a main body (1) with a holder or handle (8) attached to it. Within the main body there is a well defined cavity (3) proximal to the tooth, where the impression material (4) is located. Once the impression material has been softened, it is placed against the occlusal surface of a single tooth and `deformed` against the tooth surface when finger pressure is applied, thereby creating an impression of the tooth surface configuration. A second cavity (2) opposite to the previously mentioned proximal cavity (3), allows the placement of a fibre optic cable for the emission of light when curing materials are used.
