• occlusal
  • The present study was carried out to evaluate the effect of the incrase in the vertical dimension, the change in occlusal area and region on masticatory muscle activity. (nii.ac.jp)
  • 1) Using a whole day EMG recording and analysis system, 24-hour masticatory electrornyograms were recorded with application of the plates to elevate the occlusal plane by 2,4, and 8mm as conditions 2,4, and 8, respectively, with the plate designed not to elevate the occlusal plane as condition 0, or without any plate as condition N. (nii.ac.jp)
  • 1) The nocturnal masseter muscle activites are significantly reduced when the interarch distance is increased by applicaton of the plates to elevate the occlusal plane widely above the rest position of the mandible. (nii.ac.jp)
  • 2) The nocturnal masseter muscle activies are decreased when given occlusal contact on one side. (nii.ac.jp)

  • functional
  • On the basis of well-founded clinical evaluations and taking into account special methodological recommendations, surface electromyography (EMG) enables the acquisition of valid and reliable quantitative data on the functional condition of the masticatory muscles as a euromuscular functional analysis.

  • teeth
  • This control of blood flow to the brain is determined by the trigeminal nervous system and is greatly influenced or controlled by input from the teeth, jaw muscles and related structures. (sleepandhealth.com)
  • Several symptoms are commonly associated with bruxism, including hypersensitive teeth, aching jaw muscles, headaches, tooth wear, and damage to dental restorations (e.g. crowns and fillings) to teeth. (wikipedia.org)
  • The large forces that can be generated during bruxism can have detrimental effects on the components of masticatory system, namely the teeth, the periodontium and the articulation of the mandible with the skull (the temporomandibular joints). (wikipedia.org)
  • Thus, the masticatory force constantly changes in eating time according to mouthful characteristic and size, so it has various effects on the maxilla and mandible through teeth in different moment. (wikipedia.org)
  • The caniniform teeth of the Neocnus were large and triangular, and its skull was deep and had a large, sagittal crest which, when used with the deep mandible likely allowed strong exertion by the masticatory muscles. (wikipedia.org)
  • fibres
  • Domestic dog breeds are a great model for studying the relationship between variation in muscle fibres and chewing performance. (mpg.de)
  • We use immunohistochemistry to quantify the distribution of muscle fibres. (mpg.de)
  • postural
  • In particular, improvements in postural stability and muscle strength have been observed as a result of voluntary jaw clenching. (frontiersin.org)
  • This could be due to the divergent motor demands associated with postural control and muscle strength on the one hand and the complex coordination of a golf swing on the other. (frontiersin.org)
  • pain
  • Symptoms of acute MMM include swelling of the jaw muscles, drooling, and pain on opening the mouth. (wikipedia.org)
  • The study showed that over 80% of all patients experiencing headaches also had masticatory muscle pain, or pain in the jaw muscles. (sleepandhealth.com)
  • This is critical information because referred muscle pain is a primary cause of all headaches It is the primary source of pain in tension headache and chronic daily headaches but is also implicated as a trigger or exacerbating factor in all headaches. (sleepandhealth.com)
  • Of the headache patients, 81.1% presented with masseter muscle pain and 47.8% with temporal muscle pain. (sleepandhealth.com)
  • This finding suggests that pericranial muscle pain may be an inducing factor of primary headache. (sleepandhealth.com)
  • A comparison between masticatory muscle pain patients and intracapsular pain patients on behavioral and psychosocial domains. (uky.edu)
  • voluntary
  • The electromyographic activities of the masseter and anterior temporal muscles were recorded during maximal voluntary clenching. (unicamp.br)
  • 1. During voluntary isometric sustained jaw pull exercise, the nuchal and sternocleidomastoid (SCM) muscles were also activated. (nii.ac.jp)
  • craniomandibular
  • In recent decades, numerous researches on human motor control have suggested the potential effect of dental occlusion and muscle activity of the craniomandibular system (CMS). (frontiersin.org)
  • Neck
  • In order to evaluate the effects of tonic vestibular reflex and the afferent impulses from the antigravity muscles of the extremities and of the trunk on an excitatory state of the neck, shoulder and back portions during the jaw exercise, 13 healthy adults were electromyographically examined in various body postures. (nii.ac.jp)
  • 4. These results might suggest that the effects of the jew exercise on the muscles of the neck, shoulder and back portions were modulated by an afferent input from the vestibular system and from antigravity muscles. (nii.ac.jp)
  • Some patients may also experience involuntary contractions of the wide muscle at the side of the neck (platysmal muscle). (wikipedia.org)
  • system
  • The study of masticatory force in different types of patients such as patients with polymyositis and dermatomyositis shows that hyposalivation and mucosal alterations can be related to the pathology of masticatory system. (wikipedia.org)
  • composition
  • Chewing force generation capabilities strongly depend on the mass, architecture and fibre composition of the jaw-moving muscles. (mpg.de)
  • performance
  • We are especially interested in the question how masticatory performance varies with changes in skull morphology. (mpg.de)
  • Potential benefits of jaw aligning appliances on muscle strength and golf performance have also been described. (frontiersin.org)
  • skull
  • By positioning the center of a stimulating coil at 9cm far inferolaterally from the vertex along a contour of the skull, four responses were induced from the ipsilateral masseter muscle. (nii.ac.jp)
  • different
  • In mammals, at least ten different myosin heavy chain (MYH) isoforms have been described from striated, smooth, but rarely in non-muscle cells. (wikipedia.org)
