  • upper and lower jaw properties

    Dear All,

    I'm working on three-dimensional finite element models of the upper and
    lower jaw. Does anybody know of literature data on the mechanical
    properties of cortical and trabecular bone in these anatomical structures or
    has anybody performed some experiments to determine these properties?
    Especially data on trabecular bone is lacking (which is probably due to the
    problem of getting trabecular bone specimens of sufficient size from the jaws).
    And then a second question related to the same field : I'm looking for
    reference data for the musculatory system of the lower jaw : direction of
    the applied muscle forces relative to the jaw, force magnitude, muscle
    stiffness, point of attachment of the muscles. Can I find some kind of
    'standard' geometrical model in literature for the jaw muscles? Has anybody
    done EMG-measurements for different chewing or biting conditions
    I would appreciate any information on these topics. Thanks in advance.
