The debate continues surrounding the use of disc removal (discectomy) as the primary surgical treatment for patients suffering from severe temporomandibular joint disorders. Furthermore, the effectiveness of pre-clinical animal models for predicting the response of the joint to discectomy in humans remains uncertain. This review compares the results of(More)
Magnesium has recently been explored as a potential biomaterial for degradable orthopedic implants but its effect on fibrocartilage remains unknown. The objective of this study was to assess the effect of high concentrations of magnesium ions on the matrix production of goat costal fibrochondrocytes in vitro. Cells were cultured using a scaffoldless(More)
The preponderance of temporomandibular joint (TMJ) disorders involving TMJ disc injury inspires the need to further explore tissue engineering strategies. The objective of this study was to examine the potential of poly (glycerol sebacate) (PGS), a biocompatible, biodegradable elastomer, as a porous scaffold material for the TMJ disc. Goat fibrochondrocytes(More)
The aim of this study was to make a comparison of the compressive properties of the goat temporomandibular joint (TMJ) disc to the mandibular condylar cartilage (MCC) and to explore the transversely isotropic biphasic model. Samples taken mediolaterally from three regions of the TMJ disc and MCC were tested in unconfined compression at strain levels ranging(More)
Animal models for temporomandibular joint disorder (TMD) or degradation are necessary for assessing the value of current and future tissue engineering therapies. After reviewing the literature, it is quite apparent that most TMD animal studies can be categorized into chemical approaches or surgical/mechanical approaches. Overall, it was found that the top(More)
