  • 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)

  • fibers
  • MMM is caused by the presence of 2M fibers in the muscles of the jaw. (wikipedia.org)
  • MMM is a disease where the immune system in a dog will start attacking the muscle fibers in his/her head because the body starts to think the fibers are bad. (pets.ca)
  • Indeed, the thickness of the hypodermis, crosstalk from different muscles, the instrumental noise and the position of the electrodes relative to the muscle fibers and the motor point can influence the sEMG signal. (stomaeduj.com)
  • periodontal
  • Headches are a Trigeminal Nerve Disorder and the largest input to the trigeminal nervous system are the jaws, the jaw muscles, the jaw joints, the teeth and the periodontal ligaments. (sleepandhealth.com)
  • This includes soft tissue anatomy (e. g. muscle, periodontal ligament) and functional performance parameters such as bite force which natural selection also acts upon. (mpg.de)
  • Bleck used a gnathodynamometer and also found out the close relation between periodontal tissue and masticatory force. (wikipedia.org)
  • Dr. Shreder, using local anaesthesia (to ignore the periodontal response) measured the maximum possible force of the masticatory system and discovered the differences in the produced force, which was approximately doubled. (wikipedia.org)
  • lateral
  • Trauma or aging of the ligaments that oppose the ac)on of the lateral pterygoid muscle are stretched or torn so when the muscle contracts the ligaments cannot return the disk to its proper position and a resulting pop upon opening and/or closure is seen. (brainscape.com)
  • Other muscles, usually associated with the hyoid such as the sternohyomastoid, are responsible for opening the jaw in addition to the lateral pterygoid. (wikipedia.org)
  • 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)
  • How do the jaws and teeth covary to achieve masticatory efficiency? (mpg.de)
  • 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)
  • efficiency
  • Bite force and occlusion are the masticatory performance parameters which are directly linked to the efficiency of food intake and processing. (mpg.de)
  • chronic
  • In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus). (wikipedia.org)
  • 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)
  • 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)
  • atrophy
  • That being said, there are other reasons for the head muscles to atrophy, and maybe your dog has something other than MMM. (pets.ca)
  • After speaking to the vets , they do not want to put my dog on prednisone because they believe he really doesnt have MMM, since the muscle atrophy is only on one side. (pets.ca)
  • Im very hopeful though, because a nerve tumor usually comes with an array of symptoms and he has absolutely none other than the muscle atrophy. (pets.ca)
  • anterior
  • Methodology: To evaluate the repeatability of the normalized indexes describing masticatory muscles sEMG, the standardized cutaneous myoelectric activity of Temporalis Anterior and Masseter muscles was recorded twice during a one week interval (Acquisition sessions T1 and T2) in 20 young healthy adults. (stomaeduj.com)
  • Study design Standardized cutaneous myoelectric activity of Temporalis Anterior and Masseter muscles was acquired twice with a one-week interval (Acquisition sessions T1 and T2) in 20 young healthy adults. (stomaeduj.com)

  • 1. During voluntary isometric sustained jaw pull exercise, the nuchal and sternocleidomastoid (SCM) muscles were also activated. (nii.ac.jp)
  • 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)
  • groups
  • In all these functions several muscle groups are involved and coordinated by the central nervous system under the influence of peripheral inputs. (stomaeduj.com)
  • This muscle draws down the corner of the mouth and lower lip or other muscle groups. (wikipedia.org)
  • However, the reflexive and autonomic functions of these muscles groups are usually intact. (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)
  • 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)
  • zygoma
  • In addition, it has spike-like upper incisors and large molar teeth, especially the last upper molars, and a strong zygoma that supports powerful chewing muscles. (wikipedia.org)
  • structures
  • As a result of muscle actions, muscle fascia of the chewing side elevates all structures , such as pelvis, which is lifted and rotated forward, resulting in a transference of the body weight to the leg of the opposite side. (wilsonaragao.com.br)

  • mouth
  • Treatment: in acute phase: Heat therapy Analgesics A soft diet Muscle relaxants (if necessary) Note: When acute phase is over the patient should be advised to initiate physiotherapy for opening and closing mouth. (wikipedia.org)
  • condition
  • This systematization proves that the condition of producing a maximum masticatory force by a person is using the general subgroup of this systematization. (wikipedia.org)
  • side
  • Meanwhile, the condyle on the chewing side (work side) is moved to the side and slightly backwards by the masseter and temporalis muscles, within the limits of elasticity of the TMJ joint capsule, which it is also informed to the brain by movement and position proprioceptors within the TMJ joint capsule.
