Dynamic Shear Properties of the Temporomandibular Joint Disc

Journal of Dental Research, 2003
Shear stress might be an important factor associated with fatigue failure and damage of the temporomandibular joint disc. Little information, however, is available on the dynamic behavior of the disc in shear. Since the disc is an anisotropic and viscoelastic structure, in the present study the dependency of the dynamic shear behavior on the direction ...

Consequences of Viscoelastic Behavior in the Human Temporomandibular Joint Disc

Journal of Dental Research, 2007
The consequences of the viscoelastic behavior of the temporomandibular joint disc were analyzed in simulated jaw open-close cycles. It was hypothesized that viscoelasticity helps protect the underlying bone, while augmenting the smoothness of articular movements.

Calcifications of the disc of the temporomandibular joint

Journal of Oral Pathology & Medicine, 1999
Calcified lesions of the temporomandibular joint discs obtained from 135 human cadavers were studied. Calcifications were observed in 92 of 250 discs by soft x‐ray radiography. Studies by light and electron microscopy and x‐ray diffraction revealed that there were two different types of calcification in the discs: apatite crystal deposition with or ...

Ultrastructure of the bovine temporomandibular joint disc

Archives of Oral Biology, 1994
Electron micrographs of tissue samples taken from the peripheral zones of bovine temporomandibular joint discs showed a preponderance of thicker collagen fibrils (mean diameter 97.6 +/- 18.9 nm), occupying a greater portion of the extracellular matrix (49.7 +/- 4.6%) and more closely spaced (mean fibril separation 38 +/- 7.2 nm) than fibrils from the ...

Proteome Analysis of Temporomandibular Joint with Disc Displacement

Journal of Dental Research, 2022
Disc displacement without reduction is a common disorder of the temporomandibular joint, causing clinical symptoms and sometimes condylar degeneration. In some cases, bone regeneration is detected following disc-repositioning procedures. Until now, however, systems-wide knowledge of the protein levels for condylar outcome with disc position is still ...

The Effect of Removal of the Disc on the Friction in the Temporomandibular Joint

Journal of Oral and Maxillofacial Surgery, 2006
The amount of friction in the temporomandibular joint (TMJ) is dependent on the joint components, including the synovial fluid, disc, and articular surface cartilage. As friction in the TMJ is less than in other (discless) joints, we hypothesized that this is caused by the presence of the disc.The frictional coefficient of the TMJ was first measured in

The function of the disc of the temporomandibular joint

The Journal of Prosthetic Dentistry, 1975
A study of the structure of the discs of the temporomandibular joints of three mammals showed marked differences among them. Since the animals selected had different basic patterns of mastication, it may be that each disc has become modified to different functions in different mammals.

Mechanisms of disc displacement in the temporomandibular joint

Australian Dental Journal, 1989
AbstractThe sign of ‘clicking’ in the temporomandibular joint is not a normal phenomenon. It is, in fact, often the first indication of potential myofascial pain or temporomandibular joint pain dysfunction syndrome and as such should be detected early and diagnosed correctly.

Chondrocyte apoptosis in temporomandibular joints with disc displacement

Journal of Oral and Maxillofacial Surgery, 2002
We sought to study the presence of apoptosis in cartilage from rabbit temporomandibular joints with disc displacement (DD), and to examine the relationship between chondrocyte apoptosis and chondrocyte proliferation.Thirty Japanese white rabbits were used in this study. The right joints of 20 rabbits were subjected to surgical DD.

Clinical Predictability of Temporomandibular Joint Disc Displacement

Journal of Dental Research, 1999
Single items from a typical clinical examination have proved disappointing in their predictive value for temporomandibular joint (TMJ) disc displacement. Only one criterion (the 12 o'clock) is used to diagnose normal disc position. According to this criterion, the posterior band of the disc should be located at the top of the condyle, at the 12 o'clock
