In apicectomies carried out after cutting out a bone cavity it is very often necessary to conduct a root treatment. The corresponding fillings must be performed under dry conditions, so that the exposed bone surface must be separated from the resection surface in order to avoid blood being able to pass into the root region to be filled, on the one hand, and any reagents that may be necessary (e.g. for irrigation of the root canal) and solid particles of matter being able to reach the bone cavity, on the other hand. For this purpose, a means is provided which permits complete lining of the bone cavity and separates the material of the latter from the root region to be filled. At the same time, the lining 10 comprises two layers 11 and 12 of different, mutually complementing functions. The lining 10 is pressed into the bone cavity 3 with an appropriate tool and is thereby simultaneously deformed and adapted to the surface 4 thereof. <IMAGE> |
