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 artificia l tooth or other dental prosthesis is secured. The edge profile of the neck final surface, subject of the present invention, to which the prosthetic stu mp 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 ba ck 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 ba se of the bone (9) whereas, in correspondence to the side faces, the edge (6) o f the final surface of its neck (3) has a curved profile with its concavity directed towards the base of the bone (9).
