Network of telocytes in the temporomandibular joint disc of rats
Acta Histochemica, 2014The 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.

Tensile Properties of the Porcine Temporomandibular Joint Disc
Journal of Biomechanical Engineering, 2003Despite 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.

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 ...

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

Temporomandibular joint disc perforation: a retrospective study
International Journal of Oral and Maxillofacial Surgery, 2017The 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 ...

The viscoelastic properties of the human temporomandibular joint disc
Journal of Oral and Maxillofacial Surgery, 1996This 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, 2009Tractional 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.

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

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 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.
