Modified 3D-printed screwdriver as a rescue innovation for activation of a mandibular external multi-vector distractor.

Device failures during critical medical procedures can jeopardize treatment outcomes. This report documents the innovative use of 3D scanning and resin 3D printing to fabricate a modified screwdriver to achieve effective activation of bilateral mandibular external multi-vector distraction devices on a patient undergoing counterclockwise craniofacial distraction osteogenesis. The modified screwdriver served as a rescue device, as the external midface device obstructed activation of the mandibular external distractors with the manufacturer-supplied activation screwdriver. By designing and fabricating a custom screwdriver, successful device activation and treatment continuation were ensured.
