AIM: Numerous studies have shown how the disc displacement, which usually occurs in an antero-medial direction, can be a factor contributing to temporomandibular joint (TMJ) pain and dysfunction. The aim of this study was to ascertain, through a critical review of the literature, current knowledge relating to anterior articular disc (ADD) in the rabbit that constitutes an extremely suitable animal model for studying the human TMJ.
METHODS:An electronic search of the MEDLINE database was performed without applying time or language restrictions and using the following key words: TMD, anterior disc displacement, rabbit, bilaminar zone. This was followed by a manual search. The articles identified were assessed to verify their pertinence, or otherwise, to the topic of investigation.
RESULTS: The articles examined were divided into the following groups according to the topic (histological and/or functional) they dealt with: experimental animal models, joint changes, elastic fibers, collagen, chondrocytes and nervous tissue.
CONCLUSION:The papers reviewed covered many aspects, both microscopic and histochemical, of the dysfunctional picture o anterior ADD, furnishing a vast body of useful information, not only from the point of view of the results recorded, but also as regards the various surgical and analytical methods used.
