“…Current evidence underlines the existence of close interrelationships between the different components of the cranio-cervicalmandibular system, with coordinated activities of the mandibular, neck and trunk muscles (Armijo-Olivo and Magee, 2007;Ceneviz et al, 2006;Ferrario et al, 2003Ferrario et al, , 2006Ferrario et al, , 2007Learreta et al, 2007;Miralles et al, 2002;Pallegama et al, 2004;Tecco et al, 2007Tecco et al, , 2008Tecco et al, , 2011Zuniga et al, 1995). In healthy subjects, a quantitative assessment of these muscles during the performance of physiological jaw and neck movements may offer some knowledge about the normal mechanisms of their integrated action and nervous control (Armijo-Olivo and Magee, 2007;Ceneviz et al, 2006;Ferrario et al, 2003Ferrario et al, , 2006Forrester et al, 2010;Learreta et al, 2007;Miralles et al, 2002;Zuniga et al, 1995).…”

“…Respecto a la posición mandibular Zúñiga y cols. (90) estudiaron la influencia de la variación de la postura mandibular en la actividad EMG de los músculos esternocleidomastoideo y trapecio durante máximo apriete y observaron una significativa mayor actividad en posición retrusiva en ambos músculos. Este conocimiento podría ser de utilidad al indicar una férula oclusal que permita eliminar los contactos dentarios retrusivos.…”

RESUMENLas férulas o planos oclusales han sido utilizadas desde hace más de un siglo, generando controversia acerca de su verdadero valor terapéutico. Esto motivó una revisión histórica y actualizada que permitiera evaluar sus efectos de acuerdo a la evidencia científica. Se discuten múltiples aspectos como el concepto de relación céntrica y su determinación como punto de inicio de tratamiento en la rehabilitación oral; el uso de las férulas para deprogramar; su efecto sobre la conducta motora oral que conocemos como bruxismo; su efecto en la actividad electromiográfica tónica, durante la deglución y el máximo apriete en los músculos masticatorios y cervicales; su influencia en la eficiencia muscular; su efecto en la carga articular y las evidencias experimentales del uso de distintas férulas sobre signos y síntomas específicos como dolor y ruido articular. Se plantean desafíos para la investigación sobre cambios degenerativos en las articulaciones, en la relación craneovertebral y en la curvatura e inclinación de la columna cervical. Se concluye que es necesario utilizar una férula diseñada para el trastorno específico del paciente y que su verdadero valor terapéutico queda demostrado al mejorar algunos signos y síntomas, en músculos masticatorios y cervicales. El conocimiento parcial del mecanismo de acción de las férulas contribuye a que persista la controversia de su utilización en el tratamiento de ruidos articulares y para revertir cambios degenerativos en las articulaciones. Persiste el desafío de nuevas investigaciones, que sustenten el uso de estos dispositivos como un método eficaz para tratar a nuestros pacientes, utilizando protocolos de manejo y controles periódicos. ABSTRACTOcclusal appliances or splints have been used for over a century, generating controversy about their real therapeutic value. This led to an updated review to assess their effects according to scientific evidence. The concept of centric relation and its determination as a starting point of treatment; the use of splints to deprogram; their effect on the oral motor behaviour known as bruxism are discussed. Their effect on EMG activity during resting, swallowing and maximal clenching in the masticatory and neck muscles; their effect on muscular efficiency; their effect decreasing the joint overload; and experimental evidence of the use of several appliances on specific symptoms such as pain and joint noise, are also treated. The true challenge is to generate new knowledge about joint degenerative changes, the craniocervical relationships, tilt and curvature of the cervical spine.In conclusion, it`s necessary to use an occlusal appliance designed for the specific condition of the patient, and its real therapeutic value is demonstrated by the improvement of some signs and symptoms in masticatory and cervical muscles. However, the action mechanisms of occlusal appliances are not fully understood. The lack of scientific support contributes to the persistent controversy of the use of these appliances in the treatment of temporomandibula...

“…The interaction between the vestibular nuclei and trigeminal system, which is then employed by the visual system and used for postural control and maintenance, strengthens the interaction between the stomatognathic system and postural control [23,[32][33][34][35][36]. Through this mechanism, interactions occur not only at the position of the mandible and cranial bone, hyoid bone, cervical spine, and subhyoid structures, but also at the position of the shoulders and dorsal and lumbar spine in TMD patients [21,37,38].…”

Systematic Review of the Correlation Between Temporomandibular Disorder and Body Posture

Background:The aim of this study was to identify well-supported evidence to aid medical treatment of temporomandibular disorder or dysfunction (TMD) in Korea by analyzing the correlation between TMD and body posture in recent international research. Methods: We looked for recent clinical studies on TMD and body posture in Korean and English databases. Bias risk was estimated using the Risk of Bias Assessment Tool for Non-Randomized Studies and the Cochrane Risk of Bias Tool for assessing randomized controlled studies. Results: Nine clinical studies, published between 2005 and 2017, were analyzed. In each, TMD was assessed using the American Academy of Orofacial Pain diagnostic criteria and the Research Diagnostic Criteria for Temporomandibular Disorder. Six studies evaluated body posture using photographs, four studies used stabilometry, and one used both photographs and stabilometry. Conclusion: Six of the nine studies found a correlation between TMD and body posture. Well-designed randomized controlled trials are needed to provide more data to assess the validity of this correlation.
