Abstract
The purpose of the current study is to establish the dynamic close-mouth view radiograph
method. Seven healthy volunteers were enrolled. Dynamic open-mouth and close-mouth
view radiographs were obtained. The odontoid lateral mass interval and the dynamic
atlantodental lateral shift (ADLS) were measured. The ADLS was 9.4±5.3% by the close-mouth
view, showing a significantly greater percentage than that of 5.3±4.0% by the open-mouth
view. The dynamic close-mouth view can be useful for diagnosis of atlantoaxial lateral
instability.
