the lingual wing and the buccal wing each have a distal end, a proximal end, an upper side and a lower side; wherein said lingual wing and the buccal wing are curved upwards on their distal ends;
the lingual wing has a first protrusion on the lower side and a first inverted ledge on the upper side of its proximal end and the buccal wing has a second protrusion on the lower side and a second inverted ledge on the upper side of its proximal end, wherein the first protrusion and the second protrusion form a funnel shape protrusion to be seated and extended circumferentially around the abutment, the lingual wing and the buccal wing forming a single integral piece configured to be separated apart from one another along a wing shearing line and a funnel shearing line,
