Temporal summation of nociceptive inputs may be an important pathophysiological mechanism in temporomandibular disorders (TMD) pain; however, it remains unknown how natural jaw function relates to underlying pain mechanisms. This study evaluated changes in pain and movement patterns during repeated jaw movements in patients with painful temporomandibular joints (TMJ) compared with healthy controls. Twenty patients with TMD with TMJ pain, and an anterior disk displacement without reduction and 20 age- and gender-matched healthy volunteers were included...

Cartilage fatigue may be a factor in the precocious development of degenerative changes in the temporomandibular joint (TMJ). This cross-sectional study estimated potential for cartilage fatigue via TMJ energy densities (ED) and jaw muscle duty factors (DF), which were combined to calculate mechanobehavioral scores (MBS) in women with (+) and without (-) bilateral TMJ disc displacement (DD). All subjects gave informed consent to participate and were examined using Diagnostic Criteria (DC) for Temporomandibular Disorders (TMD) and magnetic resonance (MR) and computed tomography (CT) images...

Temporomandibular joint (TMJ) anterior disc displacement without reduction (ADDwoR) is a common type of temporomandibular joint disorders. Most patients experience limited mouth opening and joint pain at the same time. The standpoint of physical therapy is the function of the joint instead of the displaced disc. The treatment aims to make symptoms disappeared and joint function regained through 3M techniques, including modality, manual and movement. For ADDwoR patients with limited mouth opening within 2 month, manual therapy may reposition disc and the following splint and movement therapy can maintain disc-condyle relationship...

Anterior disc displacement (ADD) of temporomandibular joint (TMJ) is regarded as one of the major findings in temporomandibular disorders (TMD). It is related to joint noise, pain, mandibular dysfunction, degenerative change and osteoarthritis. In the mean time, the pathological changes were found in synovial membrane and synovial fluid. Hyaluronic acid is a principal component of the synovial fluid which plays an important role in nutrition, lubrication, anti-inflammation and cartilage repair. The synthesis, molecule weight, and concentration of hyaluronic acid are decreased during TMD and cause TMJ degenerative changes...

Temporomandibular joint (TMJ) anterior disc displacement (ADD) is one of the most common TMJ disease. However, the treatment of ADD have been far from reaching a consensus. In this article, we focused on the following three aspects: ①The relationship between ADD and condylar resorption. ②Whether disc reposition can stop condylar resorption or even make condylar regeneration. ③Proposing a more reasonable treatment pattern, that is TMJ-jaw-occlusion comprehensive treatment protocol.

Anterior disc displacement (ADD) of temporomandibular joint (TMJ) is one of the common oral diseases. The TMJ can be remodeled after disc displacement. The author's recent studies show that remodeled bilaminar zone is similar to the disc in composition and functions. The remodeled condyle can match the disc-like bilaminar zone. The new disc-condylar relationship can, to a certain extent, restore the function of the TMJ. Based on these studies, the author believes that the adaptive remodeling in TMJ has important guiding significance for clinical treatment and discusses the views of the treatment decision for various stages of temporomandibular disorders...

Sounding takes the highest prevalence of the signs of temporomandibular disorders (TMD). The well accepted theory of the mechanism for temporomandibular joint (TMJ) sounding is the internal derangement typically characterized by disc displacement. However, according to literature, there are approximately one third of asymptomatic joints in population had disc displacement, and, on the other hand, there are one fourth of TMJ sounding patients had not signs or very limited signs of disc displacement. Replacing the displaced disc to the normal position via methods like surgical operation did not achieve satisfactory long-term outcomes...
