Procedure for Taking Pre and Post Stimulation DORAs
In order to determine changes in the bony parameters of the skull, it is necessary to fix the head in a positioning device for accurate comparisons of radiographs over time (Dental Orthogonal Radiographic Analysis method manufactured by Margraf Co., Jenkintown, PA). Following equipment is required:
Procedure – Pre Proprioceptive Stimulation (Important, take the film while the Patient is Standing)
Procedure – Post Proprioceptive Stimulation
Important: If multiple DORA Xrays are taken, it is necessary to eliminate any possible engramming between films which can result in a postural distortion. This can be done by removing the proprioceptive device (e.g., insole or dental orthotic) and have the patient walk around the room for five minutes.
The following four Cranial Xrays are taken when evaluating mixed postural distortion patterns originating from the feet and the occlusion:
DORA Analysis of Films (Clinical Example)
Statistical Analysis of Above Five (5) Angles, Pre and Post Stimulation:
Using a clear plastic ruler, draw a vertical line from the center of the nasion to the tip of the anterior nasal spine. This line should bisect the odontoid process along its longitudinal axis (See DORA Tutorial).
