An inlay for connection to a dental implant, including implant connection geometry, for connecting the inlay to the implant and, coronal of the implant connection geometry, a post portion extending along a longitudinal axis, the post portion having a circular symmetric external surface and including at least one protrusion extending radially beyond said external surface, wherein the post portion further includes longitudinally extending grooves which extend radially inward of said external surface and are located directly adjacent to and on either side of the at least one protrusion such that the proximal end of said at least one protrusion is located radially inward of said external surface. The inlay is used in combination with an overlay including an accommodation cavity for housing the post portion of the inlay, the accommodation cavity having a circular symmetric cavity wall and at least one groove dimensioned such that the one or more protrusion of the inlay can be housed in the one or more groove of the overlay in order to inhibit relative rotation between the components.
