Abstract
An endosseous implant body for affixing an orthopedic prosthesis into bone is provided. The implant body generally has at least four segments disposed proximate to a coronal end of the implant body. Each segment consists of a frustro-conical compression moiety and a frustro-conical tension moiety. The angles of incidence and the surface areas of the compression moieties are chosen so that, when the body is implanted into bone and a lateral force is applied to the coronal end of the body, that portion of the lateral force which is exerted by the compression moiety of each segment against the surrounding bone is greater than that portion of the lateral force which is exerted by the compression moiety of an adjacent segment disposed more proximate to the coronal end. Likewise, the angles of incidence and the surface areas of the tension moieties are chosen so that, when the body is implanted into bone and a lateral force is applied to the coronal end of the body, that portion of the lateral force which is exerted by the tension moiety of each segment against the surrounding bone is less than that portion of the lateral force which is exerted by the tension moiety of an adjacent segmen…
