1. A device for guided surgery on zygomatic bone implants for dental prostheses, the device comprising:
at least one guide comprising a first half-bushing and a second half-bushing which are complementary and connected by a pair of bars;
wherein:
the first and second half-bushings and the bars define a common longitudinal median axis between them;
the first half-bushing is spaced apart from the second half-bushing in a direction along the median axis with the pair of bars therebetween such that the first and second half-bushings do not overlap each other when viewed from a direction perpendicular to the median axis;
the first and second half-bushings have a U-shaped or semicircular cross-section with mutually opposite concavities directed toward the median axis; and
the first and second half-bushings and the bars are arranged such that an implement used during the guided surgery, when received by the first and second half-bushings, is movable only along the median axis and is rotatable about an axis of rotation that coincides with the median axis.
