A dental implement for use in connection with filling of tooth cavities with amalgam or a similar tooth filling material, characterized in that it is made as a hand tool having a narrow outlet spout for amalgam and an amalgam container communicating with the spout for dispensing amalgam therethrough, and a vibrator unit serving to vibrate a tool part by means of which the amalgam in the cavity can be compressed or condensed. In the outlet spout there is mounted a plunger or hammar element connected to a vibrator and serving to push the filling material into the tooth cavity in a beat like manner with a relatively high working frequency, e.g. 500 cycles per minute, whereby it is possible to rapidly fill the cavity with many small portions of the filling material and with positive compression or condensation of each of these portions. The advantage of using the device is not only a considerable saving of work but also that in practice it becomes possible to fill the tooth cavity according to the so-called "wet" method whereby a filling of a highly improved quality is obtainable. |
