Temporomandibular joint sounds in patients with disc displacement

International Journal of Oral Surgery, 1985
Temporomandibular 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 ...

Biochemical analysis of the porcine temporomandibular joint disc

British Journal of Oral and Maxillofacial Surgery, 2006
Tissue 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

The viscoelastic properties of the human temporomandibular joint disc

Journal of Oral and Maxillofacial Surgery, 1996
This study evaluated the viscoelasticity of the human temporomandibular joint (TMJ) disc by comparing the moduli of elasticity generated by compressing disc specimens under two different loading rates.Twelve TMJ disc specimens 4.25 mm +/- 0.15 mm in diameter were obtained from fresh cadavers between 65 and 75 years of age.

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.

A model for temporomandibular joint disc repositioning surgery

Journal of Oral and Maxillofacial Surgery, 2001
The 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 ...

Lubricin in human temporomandibular joint disc: An immunohistochemical study

Archives of Oral Biology, 2012
To evaluate, immunohistochemically, the presence and distribution of lubricin in human temporomandibular joint (TMJ) discs without any degenerative changes, obtained from autopsies, in order to elucidate the TMJ lubrication system and disc tribology.Immunohistochemistry for lubricin detection was carried out on 34 TMJ discs.

Human temporomandibular joint disc cartilage as a poroelastic material

Clinical Biomechanics, 2003
The hypothesis was tested that a poroelastic material model is potentially able to describe the mechanical behavior of cartilaginous tissues in dynamic indentation experiments.Design. This hypothesis was tested by comparing the results from model predictions with results obtained from cyclic indentation experiments.The characteristics of cartilaginous ...

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.

Revue de stomatologie, de chirurgie maxillo-faciale et de chirurgie orale, 2017
Temporomandibular 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.

Microstructural, Micromechanical Atlas of the Temporomandibular Joint Disc

Journal of Dental Research
The temporomandibular joint (TMJ) disc is mainly composed of collagen, with its arrangement responding to efficient stress distribution. However, microstructural and micromechanical transformations of the TMJ disc under resting, functional, and pathological conditions remain unclear. To address this, our study presents a high-resolution microstructural
