A Comparison of Loading on a Single or Double Temporomandibular Joint

Abstract

This research is a continuation of our previous study on temporomandibular joint (TMJ). The aim of the research is to investigate the mechanical behaviour of the TMJ, in response to cyclical loading caused through actions of speech and mastication. This study investigates whether a difference exist between the left and right side TMJ simulation and discover a method to reproduce the action of the upper jaw bones on the lower jaw bones as much natural as possible. A set of in vitro experimental tests have been performed on a fresh sheep jaw bone to examine the hypothesis of the study. The study was concluded that the amount of loading is effective on the displacement/elongation of the TMJ.
