Abstract
The implant comprises a molding which consists of a metal having an open-cell structure permitting bone tissue to grow in with subsequent formation of bone in the cells and which is provided with an upper conical recess for insertion of an adhesion cone to be fixed in the recess by static friction. The cone is provided on one side with a flattening which comes into contact with a corresponding wall part of the recess in the implant, the cone being connected or connectable to the replacement tooth.
