Occlusion and facial pain.

I Klineberg

    Australian Dental Journal
    |February 1, 1978
    PubMed
    Summary

    Occlusion influences jaw muscle activity and myofascial pain through neurological mechanisms. While occlusal therapy may help acute pain, chronic pain involves complex psychophysiological factors beyond occlusion.

    Area of Science:

    • Neurology
    • Dental Science
    • Pain Management

    Background:

    • Occlusion, or how teeth fit together, is analyzed for its role in jaw muscle hyperactivity and myofascial pain.
    • Neurological mechanisms linking occlusal variations and anxiety to jaw muscle activity are explored.

    Purpose of the Study:

    • To analyze the role of occlusion in the etiology of reflex jaw muscle hyperactivity and myofascial pain.
    • To propose neurological mechanisms explaining the influence of occlusal morphology and anxiety on jaw muscle activity and pain.

    Main Methods:

    • Analysis of the role of occlusion in jaw muscle hyperactivity and myofascial pain.
    • Proposal of neurological mechanisms involving segmental and suprasegmental influences.
    • Evaluation of controlled occlusal therapy for acute myofascial pain.

    Main Results:

    • Occlusal variations and anxiety states significantly affect jaw muscle activity and contribute to myofascial pain.
    • Controlled occlusal therapy can alter neurological control, potentially resolving acute muscle hyperactivity.
    • Chronic myofascial pain dysfunction is not primarily occlusal, involving complex psychophysiological mechanisms.

    Conclusions:

    • Occlusal factors are crucial in acute myofascial pain linked to jaw muscle hyperactivity.
    • Chronic myofascial pain involves intricate psychophysiological mechanisms, with occlusion playing a lesser primary role.
