Abstract: A guide for guided surgery on zygomatic bone implants for dental prostheses includes a half-bushing and a complementary half-bushing which are connected by a pair of bars. The half-bushings and the bars define a common longitudinal median axis between them; the half-bushings have a U-shaped or semicircular cross-section with mutually opposite concavities directed toward the median axis; the half-bushings and the bars form a seat in which it is possible to insert a work member, such as a burr and a subsequent implant, which can move only along the median axis and rotates about an axis of rotation that coincides with the median axis.

Abstract: An external drive apparatus for bendable collar implants includes a male fastener and a female driver. The male fastener is constructed as a rigid and integral unity including an implant screw, a collar, and a male screw-top drive. The female driver supports a female screw-top drive. The female driver is configured for application of an implantation torque to the implant screw via the male screw-top drive which is disposed distally away from the collar.

Abstract: A medical apparatus for orienting and guiding a medical implement includes a mechanical mechanism that includes a first mechanism portion and a second mechanism portion. The first mechanism portion includes a contact element for disposition on a selected emplacement on a portion of a body, and the second mechanism portion includes an operation module for guidance and support of the medical implement. The mechanical mechanism permits displacement of the contact element and the operation module relative to each other in bidirectional motion of translation along a segment of a straight line, and maintains the medical implement in permanent aim at the selected emplacement. The operation module also supports an implement guide for support an implement drive which includes a motorized drive for operating medical implements coupled thereto.

Abstract: An apparatus for implantation of a zygomatic implant in coincidence with an implantation vector includes a dedicated dental tool and a dental implantation guide including a guide shell configured to conform to and to be releasably affixed to a portion of a maxillary bone. The guide shell supports a plurality of guides including an anterior guide and a posterior guide which together form a pair of guides that are distanced apart relative to each other, are configured to be aligned with the implantation vector, and are configured as concave troughs for support of a cylindrical body, the cylindrical body being at least one of the zygomatic implant, the dedicated dental tool, an implantation drill, and a preliminary drill.
