         5 . The implant ( 1 ) as claimed in  claim 4 , wherein the fitting cylinder bore ( 31 ) forms a fit ( 35 ) and/or a threaded connection with a stem ( 34 ) of a tooth replacement component. 
     
     
         6 . The implant ( 1 ) as claimed in  claim 4  wherein the fitting cylinder bore ( 31 ) comprises a cylindrical proportion ( 33 ) of between 20% and 50%, measured on a cylindrical lateral surface of the fitting cylinder bore ( 31 ). 
     
     
         7 . The implant ( 1 ) as claimed in  claim 1 , wherein a further portion of the receiving opening ( 2 ) is realized as an internal thread ( 8 ). 
     
     
         8 . The implant as claimed in  claim 7 , wherein the internal thread ( 8 ) is arranged distally with respect to the inner polygon ( 3 ). 
     
     
         9 . The implant as claimed in  claim 8 , wherein the receiving opening ( 2 ) comprises a cylinder ( 19 ) between the internal thread ( 8 ) and the inner polygon ( 3 ). 
     
     
         10 . The implant ( 1 ) as claimed in  claim 1  wherein a further portion of the receiving opening ( 2 ) comprises part of a bayonet closure ( 9 ). 
     
     
         11 . The implant as claimed in  claim 10 , wherein the bayonet closure ( 9 ) is arranged on a proximal end of the receiving opening ( 2 ). 
     
     
         12 . The implant ( 1 ) as claimed in  claim 1 , wherein the indexing ( 4 ) is realized in a graphic and/or physical manner, preferably by means of at least one notch ( 10 ), groove, recess or bore. 
     
     
         13 . The implant ( 1 ) as claimed in  claim 12 , wherein the indexing ( 4 ,  4 ′) is realized as a polygon, preferably a nonagon. 
     
     
         14 . The implant ( 1 ) as claimed in  claim 13 , wherein the polygon comprises sides of different lengths, preferably three short and six long sides. 
     
     
         15 . The implant ( 1 ) as claimed in  claim 1 , wherein the implant ( 1 ) is produced from a ceramic material, preferably from zirconium dioxide and/or aluminum dioxide. 
     
     
         16 . A tooth replacement system comprising an implant as claimed in  claim 1 , wherein the indexing ( 4 ) corresponds with a proximal recess ( 17 ) which is matched to a geometry of the indexing or with other positive locking means of a tooth replacement component ( 11 ). 
     
     
         17 . The tooth replacement system as claimed in  claim 16 , wherein the tooth replacement component ( 11 ) comprises a proximal recess ( 17 ) in the form of a polygon on a side that corresponds with the indexing ( 4 ). 
     
     
         18 . The tooth replacement system as claimed in  claim 16 , wherein the proximal recess ( 17 ) of the tooth replacement component ( 11 ) interacts in a positive locking manner with the indexing ( 4 ) of the implant ( 1 ) such that said recess ( 17 ) is aligned precisely at a desired angular position in relation to the inner polygon ( 3 ) of the receiving opening ( 2 ) of the implant. 
     
     
         19 . The tooth replacement system as claimed in  claim 18 , wherein the proximal recess ( 17 ) of the tooth replacement component ( 11 ) engages axially in the indexing with reference to a longitudinal axis of the implant. 
     
     
         20 . The tooth replacement system as claimed in  claim 18 , wherein the tooth replacement component ( 11 ) is constructed in two parts, the first part ( 12 ) includes a screw thread ( 20 ) which is connectable to an internal thread ( 8 ,  32 ) of the implant ( 1 ) and the second part ( 13 ) corresponds with the indexing ( 4 ) of the implant ( 1 ).
