Effect of interocclusal appliance on masticatory
performance of patients with bruxism.
 Laskin (1969) reported that the etiological factor that cause of temporomandibular joint disorder is muscular hyperactivity induced by abnormal contraction and relaxation of various masticatory
muscles, psychological stress and parafunctional oral habits, that may lead to muscular fatigue, causes spasm, and restricted jaw movements resulting in temporomandibular joint dysfunction, further noted that this disorder may cause occlusal disharmony, deformation in articulation leading to alteration in muscular activity.
With advancement in preventive and restorative dentistry for the management of caries and periodontal disease, tooth loss remains a concern especially in older population.1 Tooth loss affects orofacial soft and hard tissue architecture compromising aesthetics, masticatory
efficiency, phonetics and oral health related quality of life.2 Various treatment options are available for replacement of edentulous jaws, which includes removable complete dentures, implant retained over denture, implant supported hybrid over dentures and implant supported fixed bridges.3-5 Removable complete dentures have been the cost-effective treatment since decades.
performance in bats has been estimated analyzing bite force in relation to body size and masticatory
Justifying the electromyographic findings of asymmetries of muscular electrical activation when there is a chewing side preference, there is description of musculoskeletal imbalances secondary to the chewing preference, reflecting in one side with more muscle work when compared with the contralateral side; having the possibility of a functional impairment of the stomatognathic system, generating unbalance of strengths during the masticatory
act, besides musculoskeletal misfits as well as misfits of the muscular electrical potential .
The first signs of destruction appear in components of the masticatory
system that have the lowest level of tolerance.
[2-4] Previous studies have addressed bite force in human beings, in the attempt to evaluate and understand masticatory
system function, considering that bite force is a component of the chewing function.
or aesthetic deficits were apparent at the 1-year follow-up.
With regard to masticatory
function, in Cases 1 and 3, the chewing function scores with the conventional resection denture were 20 and 45, respectively.
Temporomandibular disorders (TMD) are defined as a musculoskeletal disorder affecting the TMJ, the masticatory
muscles, and associated structures including dental occlusion and the cervical spine [2, 3].
Temporomandibular disorders (TMDs) is a collective term that involves several clinical problems affecting the masticatory
muscles, temporomandibular joints and associated structures (1).
Consequent head and neck computed tomography revealed hypoxic--ischaemic encephalopathy and fatty degeneration of masticatory
