Examples of Class II Occlusion as a result of abnormal foot motion.  Note the long, narrow craniums (flexed sphenoid bone).

Loss of vertical facial dimension (Rothbart 2008)

The Ascending Postural Distortion Patterns can result in Class II Malocclusions.

  • Class II Malocclusions are due to a sphenoid bone locked flexion

Either the Rothbarts Foot or the PreClinical Clubfoot Deformity can result in a Class II Malocclusion.

Rothbarts Triad  resulting from Gravity Drive pronation

  • Posterior (External) Temporal Rotation 
  • Flexion Sphenoid Bone
  • Class II Malocclusion ‚Äč
  • A Loss of vertical facial dimension (See Face Photo below)
  • Narrowing the Curve of Spee which can crowd the teeth (See Photo Before), and if severe enough
  • 'Block out' the emergence of the primary cuspids (See Photo Below)

Narrow Curve of Spee

Ascending Postural Distortion Pattern

  • Rothbarts Foot or the PreClinical Clubfoot Deformity will drive the innominate bones into an anterior (internal) rotation, the more anteriorly rotated innominate bone being ipsilateral to the more pronated foot.
  • Anterior rotation of the innominate bones can drive the temporal bones into a posterior (external) rotation, the more posteriorly rotated temporal bone being ipsilateral to the more anteriorly rotated innominate bone.
  • Posterior rotation of the temporal bones can force the sphenoid bone into a flexed and side bent position (unleveling the pupils) resulting in:

Sphenoid - Occlusal Link

  • When the sphenoid is locked in flexion, the Curve of Spee narrows
