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...

“…So far, various stimuli have been used, e.g., auditory [7], electrical [10,11], vibratory [9], and taste [8]. There is evidence that contingent electrical lip stimulation or auditory feedback can be used to suppress SB events [7,10]. A recent study also reported [11] that the use of contingent electrical stimulation on the temporalis muscle caused a reduction of 54-55% jaw muscle EMG events per hour of sleep and that the reduction lasted for some days even when the stimulator was turned off.…”

“…SB has been associated with a multitude of effects such as tooth wear (attrition), fracture and/or failure of fillings, restorations, and implants, muscle hypertrophy, pain in teeth, jaw muscles, and the temporomandibular joints, and temporomandibular disorders (TMD) [4]. Many different treatment options for SB have been suggested, for example, occlusal appliances [5], pharmacological therapy [6], biofeedback or contingent stimulation [7][8][9][10][11], hypnotherapy [12], massed practice [13], and muscle relaxation [14].…”

Objective: To evaluate variation of electromyographic (EMG) activity and sensitivity between different sites of anterior temporalis (AT) muscle. Material and methods:Sixteen healthy subjects (eight men: 28.8 ± 5.2 year old and eight women: 29.1 ± 3.9) participated in one experimental session. EMG activity during masticatory muscle contraction was recorded from nine sites at the AT muscle in 3 x 3 grid with 1 cm between. The subjects maintained steady 30% of maximal voluntary contraction (MVC) using visual feedback. The surface EMG electrode was moved sequentially between these nine test sites and the contractions were repeated. One site was tested four times to assess test-retest variability. The sensory threshold to electrical stimulation and impedance was also measured at the same sites as the placement of EMG electrodes. Results:The 30% MVC force values did not differ between sites (P = 0.863) or within the same site (P = 0.995) due to the feedback. The EMG activity during 30% MVC was highest at the anterior-superior site (P < 0.05) with a marginal difference within the same site (P = 0.044). Impedance was higher at the posterior-superior, posterior-middle, and posterior-inferior sites (P < 0.05). The sensory threshold was highest at the posterior-superior site (P < 0.05). Conclusions: These findings showed that electrodes close to the hairline have higher impedance and sensory thresholds and should be Acta Odontol Scand 13/03/2012 3 avoided. The anterior-superior site produces the highest EMG activity and lower sensory thresholds and can be recommended as the optimal site to place the electrode for contingent stimulation.
