Abstract

In a computerized program based on the conditions in the Dentatus articulator, those errors were calculated and graphically represented which resulted from the inaccurate registration of the following parameters: Sagittal and caudal distance of incisal point to condyle axis, condyle dise put into relation to 2 mm laterotrusion of a molar point. In both the frontal and the horizontal plane, the individual parameters led to differently great errors which influenced the working and the balancing sides differently. The greatest errors occur when changing the angle of the inclination of the mandibular condyle path and the sagittal and caudal distance of incisal point to condyle axis. Errors of several tenths of a millimeter in the frontal plane are potential disturbing factors.
