<p>It is destined primarily, to reproduce the occlusal surface anatomy of a particular tooth by means of an impression material, and after the setting of such material and having obtained the 'print' of the tooth, use the device as a fininshing mold for the restorative material. The device is composed of 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 going to be 'deformed' against the tooth surface when finger pressure is applied, therefore the tooth surface configuration will be obtained, specially the one related to the restorative material (12). 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. <IMAGE></p> |
