Abstract: A transfer jig for implant dental surgery uses a tubular post and a tubular coping which is attachable and detachable from the post by a snap-fit attachment. The post has a hexagonal portion for location in a hexagonal socket in an implant and a frusto-conical portion which is a seat for the coping. The coping has a diametrically opposed pair of slots in its end that seats on the post to receive a diametrically opposed pair of pins with a snap-fit, the pins being mounted on the post so that the coping is precisely located relative to the hexagonal portions. The coping also has apertures formed through its tubular wall through which dental impression material is forced to form structural links when a dental impression is taken.
