Abstract: This implant comprises a body (1) consisting of a smooth head (2) and of a cylindrical rod (3) threaded over the whole of its length, and whose end (13) is rounded, straight longitudinal grooves moreover being made starting from the rounded end (13) over part of the length of the threaded rod (3), and one or several diametral transverse holes (15) being formed at the halfway point or a lower point of the body (1) of the implant; these features permit a more intimate immobilization of the implant with the osseous elements in the bone socket (alveolus), and they contribute to limiting the compression of the bone and therefore oppose its becoming brittle through demineralization; the undestroyed osseous debris is collected in the grooves (14) and in the hole (15), which thus permits an ossification and a transvascularization the implant, the hole (15) moreover limiting the dehiscence of the bone from its smooth head (2).
