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

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.

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

Network of telocytes in the temporomandibular joint disc of rats

Acta Histochemica, 2014
The phenotypes of the temporomandibular joint (TMJ) disc cells range from fibroblasts to chondrocytes. There are relatively few reported studies using transmission electron microscopy (TEM) to determine the ultrastructural features of these cells.

A microscopic survey of the human temporomandibular joint disc

Journal of Oral Rehabilitation, 1997
summary The articular disc of the temporomandibular joint was studied in a foetuses and children group (GI), a dentate group of adults (GII) and an edentulous, elderly group of humans (GIII) by light microscopy. The main, constituent bundles of type I collagen fibres are stratified and are orientated sagittally, transversely and obliquely in the ...

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 ...

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.

Tractional Forces on Porcine Temporomandibular Joint Discs

Journal of Dental Research, 2009
Tractional forces on the temporomandibular joint (TMJ) disc predispose tissue fatigue. This study tested the hypotheses that tractional forces: (1) increased with stress-field velocity ( V) and aspect ratio ( AR, contact area diameter/cartilage thickness), and compressive strain (ε); and (2) varied depending on cartilage thickness.

Temporomandibular joint disc perforation: a retrospective study

International Journal of Oral and Maxillofacial Surgery, 2017
The aim of this study was to evaluate disc perforation diagnosed in patients undergoing arthroscopy of the temporomandibular joint (TMJ). A retrospective analysis of 33 patients with disc perforation (35 joints) was performed. Patients and joints were divided into two groups: those with distal perforation (DP; perforation of the retrodiscal tissue, or ...

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.
