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: 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.

Abstract: Apparatus for precisely measuring the location of points on working media, such as a PCB, includes: a base panel having a surface area at least equal to that of the largest working medium to be measured, a reference mark, and a grid of fiducial marks each located at precisely-known locations with respect to the reference mark; a coarse positioning device movable over the base panel; a fine positioning device carried by and movable over the coarse positioning device; and a holder for holding a working medium substantially in contact with the base panel. The apparatus further includes first measuring means for measuring the location of a preselected point on the coarse positioning device with respect to a preselected fiducial mark of the base panel; and second measuring means carried by the fine positioning device for measuring the location of a point to be measured on the working medium with respect to the preselected point on the coarse positioning device.
