Class II MalocclusionLinked to Posterior Rotation of the Temporal Bones
Type II and Type III Malocclusions (Rothbarts Model)
The Pure ascending postural distortional patterns that result in Class II and Class III Malocclusions are due to the locked extension or flexion of the sphenoid bone. Either the Rothbarts Foot or the PreClinical Clubfoot Deformity can result in a Class II Malocclusion.

My January 2013 study based on 3D rendering of computer models suggests that
Class II Malocclusions can be the direct result of abnormal pronation.
In October 2013, I published a paper in the Journal of Craniomanidublar and Sleep Practice
that radiographically demonstrates this foot to cranial link.

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.
Ascending Postural Pattern
Postural distortions occur sequentially, from bottom to top.
