Cranial strains and malocclusion: III. Inferior vertical strain.

This article describes the Inferior Vertical Cranial Strain, one of the seven possible cranial strains that are discussed in this series of articles. Clinicians have to understand cranial strains to better treat their patients. There is a major link between the malocclusion we see and the underlying physiology of the patients. With airway restriction, it is necessary to understand the cranial, postural and facial factors as well as the soft tissue contribution for a more effective overall treatment of the patient.
