Abstract

An appliance was constructed to measure the maximum opening force, whereas, a gnathodynamometer was utilized to record maximum closing force of 44 subjects. The collected data was analyzed by computer, regardless of sex, to determine both the mean and the standard deviation of the opening forces, and the average right and left side closing forces. The data was also computed for the above mentioned variables to find out the mean and the standard deviation for both sexes. The Student's t test was utilized to determine if there were any significant differences in the before mentioned variables. A linear correlation analysis was made using data of age and measured forces to see if a relationship existed.

The following conclusions were obtained from this investigation.

  1. Right side and left side for each skeletal type did not show any important difference.
  2. Each skeletal type exhibited significant positive correlation between maximum opening and closing forces.
  3. Skeletal open and closed bite subjects did present significant difference in measuring the maximum opening and closing forces.
  4. Maximum biting and opening forces tend to be greater in males than females, but the results were only of borderline significance.
