3D-printed head phantom. (A) Axial views of phantom design with compartments and a built-in grid. (B) Dental model and mouth-guard field correction device are mounted on the 3D-printed phantom. A rubber stopper is inserted in an opening on the forehead for filling the phantom with a solution. (C) External device is added, and a saline bag is added dorsal to the dental model to mimic the cervical soft tissues. The intra-oral device and external device are separated by 5 mm of paper mimicking the upper lip.
