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

Movements of the Temporomandibular Joint Disk

Seminars in Orthodontics, 2012
The etiology of temporomandibular joint (TMJ) disorders, including osteoarthritis, is largely unexplained. TMJ disk integrity is crucial, as its failure appears to precede degeneration of the joint. During mandibular function, the TMJ disk undergoes displacements and deformations, generating strains and stresses.

Biomechanical behavior of the temporomandibular joint disc

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2003
The temporomandibular joint (TMJ) disc is a poorly understood tissue that is commonly subjected to pathologies that can lead to a locked jaw and severe pain, making daily activities such as talking, laughing and eating almost unbearable. Tissue engineering is a potential treatment for various pathologies of the TMJ disc.

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 ...

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 ...

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.

Tensile Properties of the Porcine Temporomandibular Joint Disc

Journal of Biomechanical Engineering, 2003
Despite the significant morbidity associated with the temporomandibular joint (TMJ), little is known about the pathophysiology of this complex joint. TMJ disc degeneration plays a central role in the progression of TMJ disorders, and therefore disc regeneration would be a crucial treatment modality.

[Effect of temporomandibular joint disc perforation on expression of type Ⅰ collagen in temporomandibular joint disc cells].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 2017
Objective: To investigate the effect of temporomandibular joint (TMJ) disc perforation on expression of type Ⅰ collagen in TMJ disc cells. Methods: The fibroblastic-like cells from the surgical removed TMJ disc tissue (disc perforation or TMJ condyle hyperplasia) were cultured.

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 ...
