Abstract
Three-dimensional analysis of condylar registrations, i. e. centric relation, muscular postition and Gothic Arch registrations, were carried out clinically.
The condylar points on the intercondylar axis of the upper articulator member were located most anteriorly by centric relation records and anteriorly by the muscular position records to the position in the intercuspation. It means that the condyle positions in the TMJs can be registered most posteriorly by centric relation records and anteriorly by Gothic Arch tracings to the intercuspal position of the subjects.
The three methods did not show the significant difference on the reproducibility of the registrations. The reproducibility on the antero-posterior and on the medio-lateral directions were better than on the cranio-caudal direction of the condylar position.
