An articulated chin rest is assembly is provided for supporting the chin of a patient under monitored anesthesia care, sedation, general anesthesia, or other medical procedure to ensure that their airway is unobscured. The assembly may comprise a clamp adaptable to grip a variety of structures, a first and a second length of rigid material sequentially and rotatably connected to the clamp, and a chin rest finally rotatably connected to the second length of rigid material. Means for rotatably linking the clamp, first and second lengths of rigid material, and chin rest allow each element to rotate in three dimensional space so that the assembly mechanically mimics, and is ultimately usable in place of, an anesthesiologist's hand for tilting the patient's head and securely supporting the patient's chin.
