Abstract: Dental raising forceps for the posterior upper molars or their remains, in the upper arcade, which has a passive part (1) and a hinge (2) that are conventional, together with a contra-angled part in bayonet form (3), and which terminates in certain moving jaws (4), in a circumferential arch, concave on the inside and symmetrical, and the cross-section of which gradually diminishes until it terminates in two points, (assuming the shape of a pair of bull's horns) which makes it possible to insert it between the last two dental pieces and which when it is moved gives rise to the distal (backwards) luxation of the last molar and its consequent loosening.
