Abstract
A change in the relative position of the elements of the temporomandibular joint, depending on the functional displacements of the lower jaw, can be mistakenly interpreted as subluxation and dislocation of the joint heads. An important condition that helps to avoid diagnostic errors in X-ray examination is the correct position of the patient's lower jaw at the time of exposure. Obtaining identical radiographs of the temporomandibular joint is achieved using a craniostat that unifies the styling.
