The three-dimensional (3D) temporomandibular joint (TMJ) model derives from a study of the cranium by 3D virtual reality and mandibular function animation. The starting point of the project is high-fidelity digital acquisition of a human dry skull. The cooperation between the maxillofacial surgeon and the cartoonist enables the reconstruction of the fibroconnective components of the TMJ that ar...

A review of the extensive work by dentists Fonder and Smith to resolve temporomandibular joint (TMJ) syndrome shows awareness of the unity of the body and the effect of TMJ dysfunction on all body systems. However, the role of the craniosacral mechanism has not been appreciated sufficiently. Results of a retrospective study of 130 TMJ patients evaluated for craniosacral dysfunction over a 9-yea...

The TMJ, a structurally and functionally complex unit, is enclosed in an articular capsule, which extends from the articular eminence and mandibular fossa superiorly to the neck of the mandibular condyle inferiorly. The condyle is covered and protected by the TMJ disc as the disc slides between the mandibular fossa and articular eminence with joint movement. The presence of the TMJ disc reduces...

BACKGROUND Despite the diverse conservative and surgical modalities for the management of temporomandibular joint (TMJ) dislocation and the controversy that surrounds them, very little has been done within the East-African setup in terms of highlighting and provoking greater interest in the epidemiology and management of TMJ dislocation. OBJECTIVE To audit the pattern of occurrence, demograph...

Temporomandibular joint disorder (TMJD) is known for its mastication-associated pain. TMJD is medically relevant because of its prevalence, severity, chronicity, the therapy-refractoriness of its pain, and its largely elusive pathogenesis. Against this background, we sought to investigate the pathogenetic contributions of the calcium-permeable TRPV4 ion channel, robustly expressed in the trigem...

Injection of glutamate into the rat temporomandibular joint (TMJ) capsule can reflexly induce a prolonged increase in the electromyographic (EMG) activity of the jaw muscles, however, the characteristics of TMJ afferents activated by glutamate have not been investigated. In the present study, we examined the effect of glutamate injection into the TMJ capsule on jaw muscle EMG activity and the e...

BACKGROUND Temporomandibular joint (TMJ) involvement occurs in up to 80% of patients with juvenile idiopathic arthritis (JIA). Currently there are no standardized procedures regarding diagnosis and treatment of this common complication of JIA. The aim of the study was to assess the current clinical practices in many countries regarding diagnosis and treatment of TMJ involvement in JIA. Pediatri...

Neurons responsive to stimulation of the temporomandibular joint (TMJ) region were recorded from superficial laminae at the trigeminal subnucleus caudalis/upper cervical cord (Vc/C(2)) junction region of cycling female rats under barbiturate anesthesia. To determine if receptive field (RF) properties or sensitivity to algesic chemicals of TMJ units vary over the estrous cycle, animals were sele...

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...
