Abstract
An enossal implant for securing a tight-fitting tooth replacement having two parts which are to be connected with one another. One part, having a bore hole, is placed in the jawbone. The other part, comprising a peg which serves to hold the replacement tooth, is replaceably inserted in the hole. The diameter of the cylindrical external wall of the peg is dimensioned larger than the diameter of the bore hole so that the peg, at body temperature, is compressed within the bore hole, but at reduced temperature can be removed from the bore hole due to reduction in the external dimensions of the peg. Such a connection is simple to handle, cannot loosen, and is practically free of cavities so that no bacterial colonies can form in the implant.
