Methods for minimizing the errors in mandibular model mounting on an articulator

Abstract

The study examines the errors that occur in mandibular mounting on a hinge-axis articulator using impression wax and an arbitrary hinge axis. The transfer of the model positions on the articulator was analysed mathematically. The error varied considerably as a function of the real hinge axis localization. It was influenced by the orientation of the occlusion plane and especially by the thickness of the impression wax. Analysis of the results provided clinical conclusions that help minimize localization errors.
