PURPOSE The purpose of this study was to evaluate the safety and efficacy of intra-articular corticosteroid injections (IACIs) of the temporomandibular joint (TMJ) in children with juvenile idiopathic arthritis (JIA) when administered by an oral and maxillofacial surgeon without imaging guidance. MATERIALS AND METHODS This was a retrospective study of children with JIA, seen at a single cente...

PURPOSE Although mechanical overloading of the temporomandibular joint (TMJ) is implicated in TMJ osteoarthritis (OA) and orofacial pain, most experimental models of TMJ-OA induce only acute and resolving pain, which do not meaningfully simulate the pathomechanisms of TMJ-OA in patients with chronic pain. The aim of this study was to adapt an existing rat model of mechanically induced TMJ-OA, t...

The TMJ articulation is a very complex system with muscles, ligaments and cartilage. The latest option is TMJ arthoplasty. The present work studies the behavior of a commercial fossa in a total TMJ implant. The most critical region is the first two screws in the condyle and the cranium. The fossa component presents some critical aspect in the stress observed. The contact point with the fossa co...

Introduction The temporomandibular joint (TMJ) is a possible localization of arthritis in patients with Juvenile Idiopathic Arthritis (JIA), with an estimated prevalence around 50%. Despite the decreasing involvement in the last years, maybe due to the current treatment strategies, TMJ remains one of the most clinically under recognized affected joints in JIA patients. The clinical examination ...

Relatively few patients develop such severe degenerative temporomandibular joint (TMJ) disease that they require total joint replacement. Current indications include those conditions involving condylar bone loss such as degenerative (osteoarthritis) or inflammatory joint disease (ankylosing spondylitis, rheumatoid, and psoriatic). Ankylosis of the temporomandibular joint (TMJ) secondary to anky...

The aim of this investigation was to study the effect of intra-articular (i.a.) corticosteroid injections (IACIs) in the temporomandibular joint (TMJ) on mandibular development in antigen-induced TMJ arthritis. Ten-week-old female New Zealand white rabbits (n = 42) were randomly divided into four groups: group A, control (no injections); group B, placebo (repeated i.a. TMJ saline injections); g...

Although some patients with temporomandibular joint (TMJ) disorders are successfully treated by nonsurgical means or by arthrocentesis or arthroscopic surgery, there is still a group of patients who do not respond to these procedures and for whom an arthrotomy and disc surgery (discoplasty) are necessary. Arthroscopy is an important diagnostic and therapeutic modality in the treatment of TMJ di...

Aims: To determine the association between more advanced stages of temporomandibular joint intra-articular disorders (“TMJ intraarticular status”), representing a transition from normal joint structure to TMJ disc displacement with and without reduction (DDwR and DDwoR) to degenerative joint disease (DJD), and patient-reported outcomes of jaw pain, function, and disability (“TMD impact.”) Metho...

In this paper we investigate the relation between lateral crossbite disorders and the sounds generated by the Temporomandibular Joint (TMJ). TMJ vibrations are recorded clinically by palpation and auscultation and also electronically by accelerometers. TMJ signals are filtered, amplified, digitized and stored on a computer. Based on joint time-frequency moments calculated from evolutionary spec...
