Abstract

Extra-oral radiographs of dry skulls on scientific or forensic context have head position as a critical procedure. The aims of this article are to present a multi-purposed head-positioning device, and to describe the new method of image acquirement using the device to adequately keep the head in a correct and safe position during radiological or tomographic exam. The design was created from an average-sized skull and then tested in 20 others with different morphologies, sizes, weights, and structural state of preservation. A series of digital and analog orthopantomographies followed by a cone-beam computer tomography were obtained to assure that the correct positioning standards and anatomical visualization were achievable. The developed device properly kept adult skulls in position for all extra-oral radiographic exams, providing to operators a secure and facilitated way to achieve the proper position standards. The device did not impair the visualization of the anatomical structures neither on radiographs nor in cone-beam computer tomography.
