“…However, Bassi et al [8] believe that the MSS appears to be more reliable than the FS, as increasing the thickness of the palate vault causes a marked lowering of the mandible during speech. Woda et al [23] also argue that habitual mandibular positions are variable, but some physiological conditions exist, which influence craniomandibular position. Consequently, in this study, we found that patients with TMD demonstrate a tendency for daytime airway collapse (Fig.…”

Patients with temporomandibular dysfunction (TMD) require antero-posterior (AP) correction of mandibular position inter alia. Determination of the limit of the AP correction using a sibilant phoneme registration (SPR) protocol is essential in not increasing muscular tonus. The aim of this study is to investigate the effect of a SPR protocol on the upper airway. Using acoustic pharyngometry data, mean airways of 46 adults undergoing treatment for TMD were reconstructed in 3-D and analyzed using finite element analysis and principal components analysis. When the mean baseline functional residual capacity (FRC) airway was compared to the mean collapsed residual volume (RV) airway, a 25% reduction in the 3-D upper airway was demonstrable (p < 0.01). When the mean baseline FRC airway was compared to the mean airway with SPR (FRC-SPR), a 12% increase was found at the oropharyngeal junction of the 3-D airway, but this finding failed to reach statistical difference. Similarly, when the mean FRC-SPR airway was compared to the mean RV-SPR airway, the amount of collapse was reduced to 16% but again no statistical difference was found. In contrast, when the mean RV airway was compared to the mean RV-SPR airway, a 15-18% increase was found (p< 0.05). It is concluded that the use of a SPR protocol may be useful in improving upper airway RV in patients, during treatment for TMD.

“…A musculatura suboccipital, de acordo com a literatura [7], está apenas relacionada à postura da cabeça. Entretanto, os dados revelaram que houve ativação dessa musculatura diante da sobrecarrega nos exercícios da língua em sujeitos Classe II/2ª divisão.…”

ResumoEste estudo tem por objetivo investigar o comportamento dos grupos musculares dos suprahioideos e suboccipitais frente à dor relacionada a exercício para fortalecimento da língua em sujeitos com distintos padrões oclusais. A amostra foi constituída por 11 indivíduos Classe I e 19 Classe II/2ª.divisão de Angle, ambos os gêneros, faixa etária de 18 a 59 anos. Foi investigado a postura da cabeça, atividade elétrica muscular e relato das sensações durante os exercícios. Os sujeitos realizaram por quatro vezes sucções de 10 ml de água com a língua por meio de um canudo. Os dados revelaram nos sujeitos Classe II/2ªdivisão, maior lateralização da cabeça (p<0,001), assimetria na atividade elétrica nos grupos musculares dos suprahioideos (p<0.05) e suboccipitais (p<0,0004) e relato de sensação de dor durante a realização do exercício (p<0,01). Revelando provavelmente a existência de um ponto gatilho do grupo muscular dos supra hioideos para a região suboccipital que pode estar associado a uma compensação da postura mandibular. Palavras-chave: eletromiografia, maloclusão, cervicalgia. AbstractThe study aims to investigate the muscular groups of suprahyoid and sub occipitals behavior in front of the pain related to tongue strengthening exercise in subjects with distinct occlusal patterns. The sample was composed of 11 individuals Class I and 19 Class II/2 nd . Angle division, both genders, age range from 18 to 59 years. Head posture, muscular electrical activity and reporting sensations during the exercises were investigated. The subjects suctioned three times 10 ml of water through a straw using the tongue. The data revealed greater head lateralization (p<0.001), asymmetry in the electrical activity in the muscle groups of the suprahyoid (p <0.05) and sub occipital (p<0.0004) in the Class II/2 nd division subjects, furthermore sensation of pain was reported during the exercise realization (p<0.01). It shows the probable existence of a trigger point from the muscle group of the suprahyoid to the sub occipital region that may be associated with a compensation of mandibular posture.

“…On the other hand, it is possible that the patients tend to push the lower jaw forward because of displacement of the tongue by the registration plates while recording the functional area. One way to counter this phenomenon is to ask the patient to retract the mandible during the tapping movements [20]. But the difference of more than 3 mm between the muscular dependent neuromuscular position and the more joint-related centric relation seems to be very high and therefore be a risk to rehabilitate the patient in a too protrusive position.…”
