摘要：
A tubular titanium dental implant having a round straight tube portion (1) and having an upper end (2) and a lower end (3). The lower end (3) is closed by the lower face (14) of the neck (4) of the implant. The right round tube portion (1) has two zones: an upper zone (5) having a slight over-thickness (6) and threads (7) arranged in a circular helix； a lower zone (8) having openings (9). The lower end of the right round tube portion (1) has slight depressions (17). The collar (4) of the implant carries on its surface (15) and at its center (10) a right cone (11) which has facets (13) towards its base (16) thus forming a straight regular polygon and at its center a thread (12). A hollow trepan will rotate a thin circular trench into the bone that will contain the right round tube portion (1). After osseointegration, the implant will be strongly immobilized externally, internally and openings obscured by bone. This implant can be placed in areas where the bone is thin and / or low density. Implant dentaire tubulaire en titane comportant une portion de tube rond droit (1) et pr?sentant une extr?mit? sup?rieure (2) et une extr?mit? inf?rieure (3). L'extr?mit? inf?rieure (3) est ferm?e par la face inf?rieure (14) du col (4) de l'implant. La portion de tube rond droit (1) pr?sente deux zones : une zone sup?rieure (5) pr?sentant une l?g?re sur-?paisseur (6) et des filets (7) dispos?s en h?lice circulaire ； une zone inf?rieure (8) qui pr?sente des ouvertures (9). L'extr?mit? inf?rieure de la portion de tube rond droit (1) pr?sente de l?g?res d?pressions (17). Le col (4) de l'implant porte ? sa surface (15) et en son centre (10) un tronc de c?ne droit (11) qui pr?sente vers sa base (16) des facettes (13) formant ainsi un polygone r?gulier droit et en son centre un filetage (12). Un tr?pan creux formera par rotation une fine tranch?e circulaire dans l'os qui contiendra la portion de tube rond droit (1). Apr?s ost?o-int?gration, l'implant s
