A tooth replacement system (1, 2, 3, 4, 5) is proposed that comprises an implant (10, 20, 30, 31, 32), for osseointegration in a jaw bone, and an abutment (40, 50, 60, 70, 80), wherein the abutment can be positioned in at least two radial angle positions by the form-fit interaction of locking means, on a proximal abutment base, and of at least one inner wall of the proximal portion of the receiving opening (11). The locking means preferably comprise an N-edge wrench socket (13, 13a) in the implant and an N*X external polygon (44) on the abutment, where N designates the number of locking surfaces (45) in the wrench socket and N*X stands for an integral multiple of N. The pairs of locking means are advantageously based on regular polygons, in each case preferably selected from the three, four, five or six series. The possibilities of simple production afford complete freedom in terms of the choice of material, such that the implants and also the abutments can be made from titanium or ceramic, and both structural parts can be used in all possible material combinations. |
