Reversing poor posture (postural distortions) in children over the age of 8-9 may require a multi-disciplinary approach even when the postural problem is initiated by abnormal foot motion.
In order to understand the inherent limitations of treating the foot only (e.g., Rothbarts Foot or PreClinical Clubfoot Deformity), a brief discussion of the pathodynamics engaging the feet and teeth is presented below.
I. Ascending pattern. Postural distortions occur sequentially, from bottom to top.
Rothbarts Foot will drive the innominates anteriorly (externally)
Anterior rotation of the innominates can drive the temporal bones into an posterior (external) rotation, the more pronated foot being ipsilateral to the more posteriorly (externally) rotated temporal bone (Rothbart, 2008).
Posterior (external) rotation of the temporal bones can force the sphenoid bone into an extended and side bent position (unleveling the pupils).
This can unbalance the maxilla resulting in a:
Loss of vertical facial dimension
Narrowing of the Curve of Spee (dental arch) (See Photo Left below), which can crowd the teeth and, if severe enough
'Block out' the emergence of the primary cuspids (See Photo Right below)
Narrowing of the Curve Blocked out teeth
of Spee
Posterior rotation of the temporal bones can place the sphenoid in extension which can narrow the Curve of Spee and push the maxilla forward (Class II Malocclusion)
In some cases, Structural malocclusion can be corrected using postural therapy(Guaglio, 1990)
Type II and Type III Malocclusions
The Pure ascending postural distortional patterns that result in Type II and Type III Malocclusions are due to the locked extension or flexion of the sphenoid bone resulting from either the Rothbarts Foot or the PreClinical Clubfoot Deformity (See Rothbarts Triad below).

II. Descending Pattern. Postural distortions occur sequentially from top to bottom
Pure Descending Postural Distortional Patterns Resulting from Dental Pathomechanics
FrontalPlane Distortions (Maxilla Roll)
My current research (August 2011) 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).
TransversePlane Distortions (Maxilla Yaw)
My current research (August 2011) also suggests that a 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 sacraliliac articulation. In time, this can lead to a sprain of the SI Ligament, clinically manifested as moderate to severe pain in the SacralIliac Articulation.
SagittalPlane Distortions (Maxilla Pitch) – pathomechanics needs to be clarified
Note: Distortions in the occlusion (maxilla) can occur in one plane or multiple planes concurrently.
III. Mixed Pattern. Postural Distortions resulting from both Ascending and Descending Patterns occurring concomitantly
Multi-disciplinary approach is required to: (1) stabilize the foot pathomechanics and (2) stabilize the occlusal imbalances.
If treatment is only directed towards stabilizing the foot (i.e., Rothbarts Foot or PreClinical Clubfoot Deformity) or only directed towards stabilizing the malocclusion (and resulting Atlas Roll), rotational distortions in the sacrum (and innominates) may persist.
Orthodontic Intervention
Braces should never be used until the posture is stable.
If the teeth are straightened in the presence of a forward head position, the forward head position or cervical curve may become locked in place and intractable to postural therapy.
Terminology
Correlating Terminology used by Orthopedists and Podiatrists to the Terminology used by Dental Orthopedists (and airplane pilots):
Oleski SL, Smith GH, Crow WT 2002. Radiographic Evidence of Cranial Bone Mobility. Cranio, 2:1, 34. Observations (Oleski Et al, 2002):The mean angle of change
measured at the atlas was 2.58 degrees, at the mastoid was 1.66 degrees, at the
malar line was 1.25 degrees, at the sphenoid was 2.42 degrees, and at the
temporal line was 1.75 degrees. 91.6% of patients exhibited differences in
measurement at 3 or more sites, (pre vs post therapy). This study concludes that cranial bone mobility
can be documented and measured on x-ray.
