A guiding device (7) for positioning dental implants comprising a tubular guide (1) made from a radio-opaque material, of the diameter required to guide a drill for implant cavities, pivoted within a radio-transparent support (3) so as to be rotatable about a transversal axis. The inner support (3) is mounted within an outer radio-transparent support (4), and can be adjustable displaced relative to the outer support (4), along a straight line. The tubular guide (1) can be made to change its inclination within the couple of supports (3 and 4) by rotating about its fixed axis, and can also be shifted lengthwise by displacing the inner support (3) with respect to the outer support (4). The optimal position and inclination of the dental implant, as radiographically evaluated, results in a correction of the inclination of the guide tube (1) and/or in a correction of the shift thereof in the vestibule-oral direction, which corrections may be brought to the guiding device (7) before blocking it in the final position with a suitable filler. The invention also concerns a method of producing drill templates (8) for implant surgery which makes use of the adjustable guiding device (7) in order to obtain the correct position and orientation of the hole to be drilled in the patient's jaw bone. Further, the invention concerns a kit of instruments and devices for use together with the guiding device (7) in applying said method. |
