Creation of disc displacement in human temporomandibular joint autopsy specimens

Biomechanical and biochemical outcomes of porcine temporomandibular joint disc deformation

“…Therefore, the mechanical integrity of the posterior attachment to the condyle may play an important role in the progression of displacement. This is supported by Eriksson et al showing displacement can be induced with superficial incisions to that region (40) as well as clinical findings where perforations are noted predominantly in the inferior posterior attachments (41, 42). A biomechanical study by Murphy et al showed that high strains in porcine TMJ disc posterior attachments were observed in the anterioposterior direction, leading to the conclusion that compromise of these attachments may contribute to displacement (19).…”

Clinical diagnosis and treatment of temporomandibular disorders in children and adolescents: a case series

“…Persistent microtrauma can also result in ligament elongation, leading to slow development of disc displacement 13,22 . In addition to trauma, various mechanical and physiologi-cal factors such as abnormal stress or strain of the condyle and/or retrodiscal ligaments, muscle hyperactivity, and malpositioning of the joint related to growth could cause displacement 23,24 . DDWoR associated with persistent limited jaw opening, TMJ pain, and degenerative joint disorder (DJD) should be addressed appropriately.…”

Structure-Function Relationships of Temporomandibular Retrodiscal Tissue

“…It has been postulated the RDT limits pathologic anterior disc displacement (Osborn 1985;Eriksson et al 1992), which would require the RDT to possess some inherent stiffness. Given its low tensile moduli and generally loose and disorganized ultrastructural arrangement, it is unlikely the RDT mechanically resists pathologic disc displacement.…”

“…Approximately 30% of all temporomandibular joint disorders (TMJDs) involve degenerative changes to the TMJ disc (Ahmad et al 2009;Schiffman et al 2010), typically including anterior disc displacement (Larheim et al 2001;Dias et al 2012). The temporomandibular retrodiscal tissue (RDT) has been postulated to restrict pathologic anterior disc displacement during jaw movement (Osborn 1985;Eriksson et al 1992). However, RDT biomechanics and ultrastructural arrangement are poorly understood, with no determination of physiologic regional variations in tensile properties or fiber organization.…”
