Abstract
Biomechanical behaviour of temporomandibular joint (TMJ) disc was investigated by means of a tensile test. Articular discs derived from eight adult dogs were used as experimental materials. Each disc was further divided into medial, middle and lateral parts, in parallel to the antero-posterior direction. The whole articular disc exhibited a non-linear stress-strain relationship, where the point of inflexion was around 150 gf/mm2. It was found that elastic modulus of the disc was approximately 3.23 ± 0.85 kgf/mm2 and 6.34 ± 1.19 kgf/mm2 in lower and higher stress regions, respectively. In addition, mechanical properties of the articular disc varied in different areas of the disc. It is shown that the disc plays an important role in reducing stress induced in the TMJ space and its susceptibility to internal stress may be different in the lateral, middle and medial regions.
