This implant (1) includes a cavity (2), which may be open or closed, that has a certain predetermined geometric shape and that is made of the same material as the implant (1), which cavity (2) contains a material (3) whose density is different from that of the material of which the implant (1) is made, and which material (3) possesses certain characteristics suitable for allowing the said cavity (2) and/or the said material (3) to be detected and displayed by means of magnetic resonance, ionizing radiation of the CAT (computed tomography) type, CBCT (cone beam computed tomography), or any other similar radiological examination, with the resulting determination of the position and orientation of the implants in the mouth of the patient. |
