The purpose of this study was to show occlusion on the simple hinge articulator optionallymounted. Modelling of upper-lower jaw and simple hinge articulator were developed. This modelling ofupper-lower jaw inserting wax bite was mounted imaginary on the modelling of simple hingearticulator by use of the computer simulation. From changes of THA(transverse horizontal axis)-incisor distance, Balkwill angle and THA deviation, eight types were mounted respectively. Afterremoval of wax bite, upper-lower jaw position changing were compared with centric jaw relation. The results were as follows:1. The change of THA-incisor distance had influence on mostly a vertical shift of upper jaw.2. The change of Balkwill angle had influence on mostly a horizontal shift of upper jaw.3. Inferior type in the THA deviations was the least shift of upper jaw.The above results suggest that the simple hinge articulator optionally mounted effect a shift ofupper jaw.
