Abstract
An improved caliper type of bite gauge, named KOM gauge, was devised. It is characterized by the three-point reference system including an additionally equipped reference arm to be placed on the forehead as a reference point. Compared with the two-reference system in the conventional caliper type gauges, the three-point reference system is much more advantageous for setting the device in place and stably supporting it during measurement.
The reproducibility of the record of the vertical dimension of occlusion was evaluated through the repeated measurements on the subjects having definite centric stop with their own natural dentition. Independently on the skill of the operator, KOM gauge reproduced the record significantly better than the conventional gauges tested. With the use of this improved gauge it is expected to minimize the risk of misestimating the vertical dimension of occlusion.
