Abstract

The new methodology presented in this article is simple, reliable, and accurate. The testing casts represented a reasonable simulation of human dentition. The artificial mouth reproduced major mandibular movement in a physiologic manner and applied controlled load instead of static load. The abutment movement sensor and the strain-gauge configurations suggested showed a higher level of sensitivity, accuracy, and reproducibility. This method was intended to be used for in vitro studies of RPD designs. It allowed recording of occlusal forces around the abutment tooth in the three axes of motion simultaneously.
