Abstract

INTRODUCTION: One of the main nerves involved in the neurological control of the stomatognathic system is the trigeminal nerve, or cranial nerve V. There are anatomical relationships that suggest the influence of portions of the trigeminal system in the coordination of posture and sight. Therefore, the sensory information from the proprioceptive receptors of the stomatognathic system can be processed with information from the vestibular and oculomotor systems; consequently the changes occurring in the stimulation of the trigeminal nerve can influence and eventually lead to imbalances in both vestibular and oculomotor systems. The existence of postural muscles chains also can explain that disorders in the function of the masticatory muscles and swallowing can be transmitted to the distal muscles by its close relationship with the muscles of the neck. These postural muscles work as a unit and are interdependent. Changes in proprioception and the trigeminal afferents, such as those occurring on the periodontal ligament after tooth loss, seem to lead to an imbalance in the postural muscles chains and consequently lead to postural changes. OBJECTIVES: Contribute to the systematization of the existing information in order to encourage the scientific discussion around this topic. METHODS: A literature search was conducted using the search engine PubMed for publications related to the keywords: "occlusion", "posture", "trigeminal nerve", "proprioception", "stomatognathic system", "balance". Inclusion criteria were articles published between 2000 and 2015 in order to achieve a significant amount of information but at the same time updated and with scientific accuracy, articles previously published were included due to their significance. CONCLUSION: Evidences continue to accumulate that neuroanatomical and musculoskeletal changes resulting from tooth loss carry risks of development of postural disorders. Recent studies show the potential role of dental occlusion and trigeminal afferent stimuli to maintain postural control.
