Abstract: A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by two rods. The upper portion includes a rest for a patient's forehead, wherein the rest for the patient's forehead rest has an arched shape vertically sliding in a suitable seat inside a crossbeam supported by the rods. A method of use of a craniostat according to the invention is also described.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes an upper portion connected to a lower portion by rods. The upper portion includes a crossbeam and rests for a patient's temples, the rests being formed by two arches articulated with the crossbeam. The arches lean on the patient's temples, and are blocked by a control system, which, in one embodiment, is configured as oscillating levers. The blocking action is caused by shape friction generated at the time of activation via the control levers. A method of use of a craniostat is also described.

Abstract: A craniostat for an extraoral dental radiographic apparatus includes a chin rest and a bite, which are optionally removable. The bite has centering surfaces of pre-defined orientation with respect to a centering position of the bite and is blocked in a blocking position by tightening the centering surfaces against tightening surfaces also having a pre-defined orientation with respect to the bite centering position, so that in tightened condition the bite is also automatically brought in correct centering position on the sagittal plane. A method of use of a craniostat is also described.
