The diagnosis and treatment of occlusal disharmonies requires an understanding ofthe
variables that affect occluding tooth contacts. Quantitative recordings of tooth contacts
and near tooth contacts are necessary for detailed analysis of occlusion. In this
study, different thicknesses of registration strips were used to assess the influence
of occlusal force and mandibular position on tooth contacts and clearance. This assessment
was made for nonworking side molars and working side premolars. There was a significant
decrease in clearance with increased occlusal force on both the nonworking and the
working sides. A significant increase of clearance was noted as the mandible moved
to the most lateral position on the nonworking side. These results indicate that the
variables of occlusal force and mandibular position represent potential sources of
disparity in the recording of tooth contacts. These variables should be considered
when occlusal examination procedures are conducted.
