Ultrastructure of the bovine temporomandibular joint disc
Archives of Oral Biology, 1994Electron 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 ...

Dynamic Shear Properties of the Temporomandibular Joint Disc
Journal of Dental Research, 2003Shear 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

Dynamic Properties of the Human Temporomandibular Joint Disc
Journal of Dental Research, 2001The cartilaginous intra-articular disc of the human temporomandibular joint shows clear anteroposterior variations in its morphology. However, anteroposterior variations in its tissue behavior have not been investigated thoroughly. To test the hypothesis that the mechanical properties of fresh human temporomandibular joint discs vary in ...

[Temporomandibular joint disc surgery].
Revue de stomatologie, de chirurgie maxillo-faciale et de chirurgie orale, 2017Temporomandibular joint (TMJ) disorders are a common disease and may be responsible for major functional and painful repercussions. Treatment is not consensual. The literature highlights the role of conservative treatments (physiotherapy, analgesics, splints) in a first attempt.

Temporomandibular Joint Soft-Tissue Pathology, I: Disc Abnormalities
Seminars in Ultrasound, CT and MRI, 2007The internal derangements are the most common noninflammatory abnormalities of the disc, observed even in asymptomatic subjects. Because the temporomandibular joint shows large adaptative and compensatory mechanisms over dysfunctional disc motion, these disorders may be asymptomatic or minimally evident for a long time.

Chondrocyte apoptosis in temporomandibular joints with disc displacement
Journal of Oral and Maxillofacial Surgery, 2002We 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.

Biochemical analysis of the porcine temporomandibular joint disc
British Journal of Oral and Maxillofacial Surgery, 2006Tissue engineering can be a boon in treating lesions of the disc in the temporomandibular joint (TMJ). Unfortunately, little is known about its biochemical content, so we analysed the discs of six slaughtered pigs. We measured the content and distribution of total DNA, glycosaminoglycan, and collagen. The mean (S.D.) content of DNA was 0.14% (0.08%) of

Dynamic compressive properties of porcine temporomandibular joint disc
European Journal of Oral Sciences, 2003This study aimed to evaluate the effect of the strain frequency and amplitude on the compressive properties of the porcine temporomandibular joint disc and to determine the time‐dependent changes associated with energy dissipation. Seven discs were used for compressive cycle tests, including various frequencies and magnitudes of compressive strain ...

A model for temporomandibular joint disc repositioning surgery
Journal of Oral and Maxillofacial Surgery, 2001The present study establishes a model of reversible anterior disc displacement using the rabbit craniomandibular joint (CMJ) and examines the period required for successful disc repositioning surgery.The left CMJ was exposed surgically in 27 animals and a suture positioned at the posterolateral portion of the disc was pulled in an anterior direction ...

Temporomandibular joint sounds in patients with disc displacement
International Journal of Oral Surgery, 1985Temporomandibular joint sounds have been viewed as signs of different pathological changes. However, the correlation between joint sounds on the one hand and function and morphology of the joint on the other, are not well documented. We have therefore presurgically recorded sound from 35 operated joints with disc displacement and have studied ...
