A dental implant is disclosed of the type which is fixed to the maxilla of the jaw bone. The implant includes a first elongated body which is externally threaded so that one of its ends can be secured into the maxilla. This body includes an axial bore which extends out of its other end. A second body forming part of the implant includes the artificial tooth at one end and, at the other end, a shaft portion of the first body. The construction permits a certain amount of axial movement between the first and second bodies, once they are fitted together and cushioning is provided between them to simulate the function of a real tooth.
