A device is used for forming holes and inserting sleeves in a unit incorporated in a dental bridge or a template for forming holes in bone. The unit comprises a shell and, arranged in the latter, a matrix material which is viscous at least in an initial forming stage and which gives the unit resiliency properties or is resilient as a function of one or more actions. The device comprises a perforating part (7) by means of which the shell and the substance can be penetrated and can be pushed aside counter to the effect of the resiliency in order to form holes or recesses. Arranged behind or under (over) the perforating part there is a sleeve-supporting portion by means of which a sleeve (5) assumes a position in the hole or recess and exposes its outside to said pushed-aside and resilient shell and substance or agent. The perforating part and the sleeve are arranged to prevent any substantial leakage of the substance or agent during the penetration and the sleeve application. |
