title: The effect of altering the vertical dimension of occlusion on biting force.
abstract: The effect of altering the vertical dimension of occlusion (VDO) on the biting force was studied in six men and seven women. The biting force was registered with a newly designed gnathodynamometer that uses two strain gauges cemented on its surfaces and a Wheatstone bridge connected to a chart recorder. Biting force was measured for each subject at the following three positions of vertical dimension: position 1, VD < VDO; position 2, VD = VDO; and position 3, VD > VDO. The recorded force at these positions was statistically different for all of the subjects. All subjects exerted significantly greater biting force when VD > VDO Men exerted greater biting forces than women, but this difference was not statistically significant.
