title: [The interrelationships between dental parameters and electronic axiographic findings. A study on subjects with nonphysiological incisor relations].
abstract: The purpose of the present study was to discern possible relationships between dental parameters and the horizontal inclination of the condyle path. Two test groups of orthodontically untreated individuals with non-physiological incisor relationships, one group with enlarged and the other with reverse overjet, were selected for the study. An opto-electronic apparatus was employed to measure the horizontal inclination of the condyle path. The dental parameters were set by clinical examination and by measuring plaster casts. Both groups exhibited significant distribution deviations in the inclination of the condyle path and in the following parameters: "occlusal contacts of the front teeth during protrusion", "overbite", "resulting overjet", and "sagittal and vertical distance of the incisal edge of the lower incisors to the zero point of the upper incisors". Statistically no correlation between the dental parameters and the inclination of the condyle path was discerned. The influence of muscular guidance is in large measure the determining factor for the large variations in the TMJ registrations, and especially in their quantitative evaluation. The results were the same even when tracings were repeated a number of times with the same patient.
