Pure Descending Postural Distortion Patterns Resulting from Dental Pathomechanics

Frontal Plane Distortions (Maxilla Roll)

  • Current research (August 2019) suggests that a roll in the maxilla (maxilla distortion on the frontal plane) results in an Atlas Roll (C1 distortion on the frontal plane).  An Atlas Roll can destabilize the entire spine on the frontal plane (e.g., augmenting the scoliotic curves).  The sacrum tilts, unleveling the spine (observed as a functional leg length discrepancy when the patient is in the supine position). Frequently pain is felt in the pes anseranus (medial compartment of the knee) and lateral ankle (Peroneal muscles).


Transverse Plane Distortions (Maxilla Yaw)

  • Current research (August 2019)  suggests that yaw in the maxilla (maxilla distortion on the transverse plane) results in an Atlas Yaw (C1 distortion on the transverse plane).  
  • An Atlas Yaw (suspected when one observes asymmetrical head rotation) can destabilize the entire spine on the transverse plane, resulting in a transverse plane slippage or rotation of one vertebrae on top of another. This is most commonly occurs at the level of the sacral thoracic vertebrae (e.g., Spondylolisthesis).
  • The sacrum yaws, generating a shearing motion in the sacral-iliac articulation.  In time, this can lead to a sprain of the SI Ligament, clinically manifested as moderate to severe pain in the SacralIliac Articulation.


Sagittal Plane Distortions (Malocclusion)

  • Dr. Gerald Smith's research suggests that a malocclusion drives the temporal bones into an anterior (internal) rotation.  
  • Anterior (internal) rotation of the temporal bones drives the innominate bones into a posterior rotation (Lovett, 1905). Malocclusion (Descending Pattern)


Note: Distortions in the occlusion (maxilla) can occur in one plane or multiple planes concurrently.
