A dental prosthesis (1) with an angled inner bore (2) is proposed, formed by a first hole (7) and a second hole (26) connected by an angled connection area (29) formed with an angle between 0º and 180º. An outer area (31) and side areas (32) of the angled connection area (29) form an elbow (40) devoid of protruding edges directed towards the interior of the inner bore (2). Said elbow (40) facilitates the insertion and extraction of a screw through the inner bore (2) during the assembly or disassembly of the dental prosthesis (1) on a dental implant. Some methods of manufacturing said dental prosthesis (1) are also proposed.
