“…The rationale for this evaluation comes from various observations, as, for example, the association between cervical posture and facial morphology (Solow and Tallgren, 1977;Solow and Siersbaek-Nielsen, 1986;Hellsing et al, 1987;Huggare and Cooke, 1994), the correlations between the surface electromyographic (sEMG) activity of the jaw muscles and that of the neck and trunk muscles (Huggare and Raustia, 1992;Holmegren et al, 1985), and the changes in sEMG activity of the sternocleidomastoid and upper trapezius (tonic and swallowing) soon after the wearing of an intraoral bite (an acrylic removable intra-oral device to reduce masticatory muscular spasm) by subjects with spasms in the mentioned muscles Moya et al, 1994).…”

“…8,9 Some authors investigated changes in the craniocervical relationship after a full-arch maxillary stabilization splint and reported significant extension of the head on the cervical column. 24,25 The results of this study indicate that insertion of CDs significantly affected the dynamic measurements of the NHP, and subjects showed cranial extension relative to the initial head postural measurements.…”

“…1,2,4,14,17e19 This position allows the clinician to evaluate the NHP and inclination of the cervical column and head. 25 It takes time for elderly subjects to adapt to changes in the oral cavity. 14,26,27 However, de Sousa et al 26 indicated that the interocclusal rest position remained constant from CD insertion throughout the assessment period of 3 months (short-term).…”

“…16e20 Several studies described significant associations between the NHP and the cervical column, 4,18 facial prognatism, 17 mandibular plane, 2 anterior facial height, 4,5,19 malocclusions, 1 sagittal height of dentoalveolar arches, 2 vertical-facial alteration of the face, 3 vertical dimension in the rest position, maximum voluntary clenching (MVC), initial occlusal contact, temporomandibular disorders, 19 muscle activity, 6 anteroposterior diameters of the pharyngeal airway, 21e23 and wearing of a full-arch maxillary stabilization splint. 24,25 Although the associations are well described for the above-mentioned structures, no evaluation of correlations between CDs and the NHP and how changes in the PAS affect the NHP were examined in detail. To clarify this relationship, the aims of this study were (1) to describe the morphology of the NHP in EPs with neutral occlusion and a normal craniofacial morphology and in the same patients after rehabilitation with CDs and (2) to evaluate the relationship between the PAS and facial morphology in EPs with and without CDs, taking into account the NHP.…”

Background/purpose: The purpose of the study was to evaluate the vertical and sagittal maxillomandibular relationship and differences in the natural head posture related to posterior airway changes in complete denture wearers using cephalometric radiographs. Materials and methods: Thirty-five complete denture wearers were evaluated cephalometrically at 3 stages. Cephalograms exposed in the natural head position at rest without a prosthesis (T 0 ), at rest with complete dentures (T 1 ), and in centric occlusion (T 2 ). Various postural and morphological landmarks were individualized on the radiographs. Results: Changes in the occlusal vertical dimension were associated with statistically significant alterations in head posture; from T 0 to T 1 extension of the head, from T 1 to T 2 flexion of the head, and cranial extension between T 2 and T 0 were significant (P < 0.001). Posterior airway dimensions significantly decreased from T 0 to T 1 and T 1 to T 2 (P < 0.001). The analysis of repeated measurements and Friedman tests were used to compare differences, and P values of <0.05 were considered significant. Conclusion: Airway protection maintenance with extension and flexion of the head is vital because any rehabilitation involves the head and neck region. Correlation coefficients indicated significant changes in dynamic measurements of the natural head position related to complete dentures. Immediate head extension and alterations of posterior airway dimensions were observed following airway obstruction because of the insertion of complete dentures.

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...
