  • Patent number: 7108509
    Abstract: Device for pushing away an enclosure arranged around a dental element. When filling dental elements, it is important that adjacent dental elements should come into contact with one another at a defined location. To this end, the invention proposes a tool for pushing the enclosure arranged around the dental element onto the adjacent dental element during the filling operation. In the vicinity of the free end, this tool is provided with a thickened section which has to push away an enclosure of this type. This thickened section is provided with a recess in the vicinity of the free end, approximately in the center. This recess forms an elevation in the filling material, and in this way shrinkage stresses can be guided out of the center of the filling material towards the outside, resulting in a shrinkage-free filling.
