Speed of Teeth Going Down

  1. Jun 17, 2011 #1
    1. The problem statement, all variables and given/known data
    How to calculate for the speed of molars and premolars going down. Lower jaw is stationary or don't move. Only the upper jaw, goes down. Upper jaw and lower jaw are connected by a pivot. The jaw was attached (the upper and lower part ) in the instron machine, with a load (2000 N) going down that pushes the upper jaw downwards. What parameters should I measure in order to derive this?


    2. Relevant equations
    Given:
    distance between the pivot and premolars= 78.3 mm
    distance between the pivot and molars= 56.5 mm


    3. The attempt at a solution
    I also measured the following:
    distance between upper and lower molar= 21.85 mm
    distance between upper and lower premolars= 23.23 mm

    I conducted compression test with compression rate of 1 mm/sec
    length of time of closure of molars= 33.03 sec
    length of time of closure of premolars= 26.25 sec
