A device (1) for dental implantation is described, i.e. a device suitable to be implanted into the maxillary or mandibular bone (in place of the root of a lost tooth) to support a prosthetic stump to which the crown of an artificial tooth or other dental prosthesis is secured. The edge profile of the neck final surface, subject of the present invention, to which the prosthetic stump is applied, basically corresponds to that of the margin of the alveolar bone crest in a state of parodontal health: in correspondence to the front and back faces of the implanted device (1), the edge (6) of the final surface (5) of its neck (3) has a curved profile with its convexity directed towards the base of the bone (9) whereas, in correspondence to the side faces, the edge (6) of the final surface of its neck (3) has a curved profile with its concavity directed towards the base of the bone (9).
Cette invention concerne un dispositif d'implant dentaire (1), c'est-à-dire un dispositif susceptible d'être implanté dans l'os maxillaire ou mandibulaire (à la place de la racine d'une dent perdue) et pouvant supporter un moignon prosthétique sur lequel vient se fixer la couronne d'une dent artificielle ou autre prothèse dentaire. Selon cette invention, le contour de la surface finale du collet sur lequel est appliqué le moignon correspond fondamentalement au bord de la couronne alvéolaire osseuse en état de santé parodontale: En face des faces avant et arrière du dispositif d'implant (1), le bord (6) de la surface définitive (5) du collet (3) présente un profil incurvé dont le côté convexe est tourné vers la base se l'os (9) alors qu'en face des faces latérales, ce même bord(6) présente un profil incurvé dont le côté concave est tourné vers la base de l'os (9).
