Correlations between posture and jaw relations
Danner, Horst-W. / Jakstat, Holger A. / Ahlers, M. Oliver
Interactions between posture and functioning of the craniomandibular system are well documented in research studies and case studies. For dentists who engage in functional diagnostics and treatment procedures, knowing these correlations is often a prerequisite for understanding the etiology and pathogenesis of craniomandibular dysfunction or disorder. Observing these correlations also helps prosthodontists to avoid problems related to the occlusal design and integration of dental restorations. A majority of the lawsuits on record following dental treatment concern reconstruction of the jaw relations or of occlusal surfaces. This article discusses the basic mechanisms of interaction between the static load acting on the body and the function of the spine and the jaw relations. Correlations are explained in such a way that they can be easily comprehended by dentists for whom judging someone's body posture is not part of their daily routine. The article focuses on malpositions leading to biomechanical stresses through a static load on the sagittal, frontal and transverse planes as well as on dysfunctions of the cervical spine and other spinal segments - particularly in the region of the sacroiliac joint - and their reciprocal effects with the craniomandibular system.

Keywords: malposition, dysfunction, vertebral column, cervical spine, sacroiliac joint, craniomandibular dysfunction
