AU - Takano-Yamamoto, T.. AU - Sugimoto, T.. PY - 2004/5/15. Y1 - 2004/5/15. N2 - Immunohistochemistry for vanilloid receptor subtype 1 (VR1), vanilloid receptor 1-like receptor (VRL-1) and P2X3 receptor was performed in the rat temporomandibular joint (TMJ). Blood vessels in the articular disk and capsule, the synovial membrane and the fibrous tissue around the condylar process were innervated by VR1- or P2X3 receptor-immunoreactive (ir) nerve fibers. However, VRL-1-immunoreactivity (ir) could not be detected in the TMJ. Retrograde tracing and immunohistochemical methods revealed that 25%, 41% and 52% of TMJ neurons in the trigeminal ganglion (TG) exhibited VR1-, VRL-1- and P2X3 receptor-ir, respectively. VR1-ir TMJ neurons were mostly small to medium-sized, whereas VRL-1- and P2X3 receptor-ir TMJ neurons were ...

PMID: 9610308 To study the role of the nervous system in temporomandibular joint arthritis, substance P-, calcitonin gene-related peptide-, and neuropeptide Y-like immunoreactivity in the trigeminal ganglia and temporomandibular joint of rats was examined. Arthritis was induced in female Lewis rats through bilateral injection of a suspension of heat-killed Mycobacterium butyricum in paraffin oil into the temporomandibular joint. Control rats received paraffin oil via the same route. Tissues were collected for neuropeptide extraction 28 days after injection and analyzed by radioimmunoassay and reverse-phase high-performance liquid chromatogrpahy. Calcitonin gene-related peptide was significantly increased in the arthritic trigeminal ganglia. Substance P, calcitonin gene-related peptide, and neuropeptide Y in the arthritic temporomandibular joint were significantly increased as compared to controls. The results of this study show that sensory and sympathetic neuropeptides may possibly be ...

You may not have heard of it, but you use it hundreds of times every day. It is the Temporo-Mandibular Joint (TMJ), the joint where the mandible (the lower jaw) joins the temporal bone of the skull, immediately in front of the ear on each side of your head. A small disc of cartilage separates the bones, much like in the knee joint, so that the mandible may slide easily; each time you chew you move it. But you also move it every time you talk and each time you swallow (every three minutes or so). It is, therefore, one of the most frequently used of all joints of the body and one of the most complex ...

TMJ refers to the Temporo-mandibular Joint, or jaw joint. You have a pair of these joints, one on each side of the head between the lower jaw (mandible) and the side (temporal) bone of the skull, just in front of the ear.The TMJs function is to allow the lower jaw to move so that you can chew and swallow, speak, yawn and do all the other normal jaw movements. This joint also allows you to clench and/or grind your teeth. The temporo-mandibular joint is a synovial joint and includes ligaments, tissue between the jawbone and the ear canal and a fibrous disc which sits between the head of the mandible (condyle) and the joint surface (articular surface) of the skull.. TMD stands for Temporo-Mandibular Disorders and includes a whole range of conditions which can affect the joint. Some clinicians will use the term TMJ to refer to these disorders.. The temporo-mandibular joint is different from the bodys other joints. The combination of hinge and sliding motions makes this joint among the most ...
Tumoral calcinosis is an uncommon clinicopathological condition which is characterized by the formation of calcium salt deposition in intra-articular or peri-articular soft tissues. It usually presents as a focal growth of hard tissue, either solitary or multiple, beneath the skin and connective tissue. Diagnostic techniques mainly include clinical and radiographic evaluation. The most commonly involved locations include the hip, elbow, shoulder and knee. Involvement of the head and neck regions are far less common. There have been 5 case reports of temporomandibular joint involvement in the literature so far. We present a case report which describes the diagnosis and management of a 59 year old female patient with chronic right temporomandibular joint pain and localized bony hard swelling over the right pre-auricular region. Patient retained normal range of motion and mouth opening. Computed tomography taken showed a radio-opaque juxta-articular ovoid mass over the right pre-auricular region in close

AU - Augustyn, G. T.. PY - 1986. Y1 - 1986. N2 - Magnetic resonance imaging of the temporomandibular joint (TMJ) was performed on two normal volunteer subjects and two symptomatic subjects using a 0.15 T resistive magnet. A spin echo pulse sequence with a TE of 38 ms and a TR of 500 ms was employed. The TMJ meniscus is a low signal structure, and the bilaminar zone behind it is a relatively high signal structure. In normal closed mouths, the demarcation between meniscus and bilaminar zone is located at the vertex position above the mandibular condyle. When the condyle translates, the posterior portion of the meniscus bulges into the joint space. Dislocated meniscus can be identified by a gray mass anterior to the condylar head. The joint space is filled with the higher signal of the bilaminar zone. In ...
This study examined the clinical and radiological effects of intra-articular tenoxicam injection following arthrocentesis and compared them with arthrocentesis alone in patients with disc displacement without reduction (DDwoR). 24 temporomandibular joints (TMJs) in 21 patients with DDwoR were studied. Patients were divided randomly into Group A in which only arthrocentesis was performed (14 TMJs in 14 patients) and Group AT which received arthrocentesis plus intra-articular injection of tenoxicam (10 TMJs in 7 patients). Patients were evaluated before the procedure, on postoperative day 7, then 2, 3, 4 weeks, and 2, 3, 4, 5, 6 months postoperatively. Intensity of joint pain was assessed using a visual analog scale. Maximum mouth opening was recorded at each follow-up. TMJ sounds and palpation scores were noted as positive or negative. Magnetic resonance imaging (MRI) was performed before and 6 months after treatment in both groups. Disc form, disc location during neutral position, reduction with ...

N2 - Aims: To test the effects of occlusal force (OF) angle on the variations in predicted muscle and temporomandibular joint (TMJ) forces during unilateral molar bites. Methods: The craniomandibular (CM) geometries of 21 individuals were determined from lateral and posteroanterior cephalometric radiographs. These geometries were used in a numerical model based on minimization of muscle effort. This model was previously validated for this subject group through the use of jaw tracking and electromyographic data. The model predicted muscle and TMJ forces associated with static OFs on the right mandibular first molar. OF angle was varied from vertical to 40 degrees in the buccal and lingual directions, in increments of 10 degrees. Results: ...

Orofacial pain associated with osteoarthritis (OA) in the temporomandibular joint (TMJ) is a significant clinical problem [1]. The pathophysiologic and cellular mediators that underlie the development of such chronic orofacial pain are not well understood, nor has a relationship to mechanical loading been defined. Several experimental models have been developed to examine causative factors in TMJ OA progression and joint pathology. Such models often involve intra-articular injections or surgical manipulation of tissue structures in order to alter joint kinematics and stability [2-6]. For example, severing of the discal attachments followed by anterior displacement of the disc has been employed in a rabbit model, while disc perforation and scraping of the condylar surface have been used in sheep models to induce OA symptoms [2,3]. A limitation of the above approaches is that they introduce artificial damage to the joint structures and do not approximate the clinical disorder of ...
In spite of the practical importance of having a detailed knowledge of knee joint innervation to understand the pathophysiologic aspects, little information is now available concerning the density and pattern of the nerve fibres which are distributed to it. The present study has been designed to investigate the density and distribution of nerve fibres and receptor corpuscles in the knee joint articular capsule, cruciate and collateral ligaments in the rat, using the acetylcholinesterase (AChE) histochemical in toto staining technique. The investigation was performed on male Wistar rats of 3 months of age, some of which had been treated with capsaicin to deplete their afferent C fibres of their content of neuropeptides. AChE-positive nerve fibres and different types of receptor corpuscle endings were found within articular capsule and ligaments. The highest density of AChE-positive nerve fibres was noticeable in the fibular collateral ligament followed by the tibial collateral ligament, the ...

e-mail: [email protected] Physiological aspects of the masticatory function. In the undisturbed masticatory system, the teeth are in neutral occlusion with each other (Figure 1). That is why, the most important is the natural contact of the cusps and fissures of the antagonist teeth, in order that all the eccentric movements wont bring any disturbance (Figure 2). The temporo-mandibular joints are in statics but also in dynamics of the same growth-related geometry, in order to have the temporo-mandibular joints as "distal pairs of occlusion".. When loaded during chewing, the involved teeth will be depending on the consistency of the alimentary bolus to be crushed, and they will be deflected spatially within their physiological mobility (Figure 3). This requires the elastic and damping properties of the periodontal apparatus. In this area there are nerve endings, on which on which are generally mechano-receptors (Figure 4).. The capture caused by the respective bolus changes the position ...

MONJE GIL, F.. Mandibular distraction and the temporomandibular joint. Rev Esp Cirug Oral y Maxilofac [online]. 2004, vol.26, n.4, pp.221-227. ISSN 2173-9161.. Abstract: Patients with severe craniofacial abnormalities often require multiple and complex surgical procedures to reconstruct maldeveloped hard and soft tissues of the maxillofacial complex. An important advance in reconstructive surgery is mandibular lengthening by gradual distraction, which takes advantage to be less agressive surgery than some osteotomies. With this technique, a bicortical osteotomy is made at the angle of the deficient mandible, and an expansion appliance is placed across the osteotomy line. Although the applied forces have been shown to lengthen the mandible effectively in the region of the application, their effects on the proximal and distal mandibular segments, including the temporomandibular joint region, have not been analyzed systematically. In this article, we study several experimental and clinical papers ...
The aim of the paper is a stress-strain analysis of the temporomandibular joint (TMJ) with subtotal replacement. The temporomandibular joint is a complex, sensitive and highly mobile joint which works bilaterally so each side influences the contralateral joint and because of this the distribution of the stresses is changed in the healthy joint as well. Detailed knowledge about function these are necessary for clinical application of temporomandibular joint prosthesis and also help us estimate the lifetime of the prosthesis a possibilities of alteration in the contra lateral joint components. The mathematical model of TMJ with replacement is based on the theory of semi-coercive unilateral contact problems in linear elasticity. The numerical solution is based on finite element approximation. The obtained numerical results will be discussed ...

What is TMD?. Temporo-mandibular joint (TMJ) is a hinge joint that connects your lower jaw to the skull, which are in front of each ear. It allows you move your lower jaw when you talk and chew.. Temporo-mandibular disorders (TMD) are problems associated with your TMJ and muscles that control it.. Symptoms of TMD. 1. Clicking or popping sounds in the TMJ when you open or close your mouth. This may or may not be painful. 2. Pain or tenderness in your TMJ area, neck and shoulders when you chew, speak, or open your mouth wide. 3. Difficulty in opening mouth and chewing. 4. Jaws may get locked when you open too ...
TMJ syndrome: Disorder of the temporo-mandibular joint(s) causing pain usually in front of the ear(s). TMJ Dislocation: Excessive contraction of the lateral pterygoids may cause the jaw to dislocate anteriorly (pass anterior to the anterior tubercles. This could happen during yawning or when taking a large bite. Also sideway blows to the chin when the mouth is open dislocates the TMJ on the side that receives the blow. TMJ dislocation is frequently accompanied by fracture of the mandible. Posterior dislocation of the TMJ is uncommon due to the resistence by the postglenoid tubercle and the strong intrinsic lateral or temporomandibular ligament. Care must be taken during repair in regards to the facial and the auriculotemporal nerve; injury to the auriculotemporal nerve leads to laxity and instability of the TMJ ...

In the course of the average week at my clinic, I see at least five people complaining of TMJ pain.. TMJ stands for temporomandibular joint. This is the spot that your jaw bone meets with your skull just underneath your ears.. The complaints will range from acute to chronic. Some patients will just wake up with pain or immobility of their jaw, or it will be an accumulative response over many weeks or months.. The TMJ is an unusual joint. It is not the ball and socket type of joint that we think of. Rather, it is a joint that glides having an unusual range of motion. When one studies the anatomy of the jaw, it becomes apparent that there is a very intimate relationship between the muscles of the jaw and the first three vertebra, or bones of the neck. If there is an aberration within the first three vertebra of the neck this will, in turn, have a direct effect on the temporomandibular joint and its subsequent range of movement. Patients will often complain of unusual movement or a lack thereof, ...
CBCT images of asymptomatic adult TMJs commonly show degenerative bony alterations. Accordingly, such radiographic findings should be used with care and only as a supplement to clinical assessment.
Methods Fourty nine patients with a mean age 37.57±15.14 years were recruited to the study. Patients were evaluated for complaints and clinical findings and then randomly allocated to three treatment groups. All patients got education and learned TMJ exercises to perform as home exercise program. The patients in the first group (n=17) received pharmacotherapy (non-steroidal anti-inflammatory drugs for a duration of 10 days with anti-inflammatory doses), the second group (n=15) received physical therapy comprising superficial local heat and TENS for 10 sessions; the third group (n=17) received hyaluronic acid injection to TMJ. The main outcome measures were pain at rest and movement of jaw assessed by VAS; and mouth opening distance. Oral health impact profile (OHIP-14) was used in all patients to assess peoples perceptions of the social impact of oral disorders on their well-being. All the measurements were performed at baseline, at the end of therapies, one month and three months after ...
Of course it does. The list of tolerated problems in pedigree dogs which will be reproduced should be revised and updated.. Truths. 1. The evaluation of occlusion contains several important criteria that include shape and symmetry of the skull, the function of the temporo-mandibular joint (TMJ), and finally position and number of the teeth.. 2. The tongue pushes teeth forward as the upper lip pushes them backward. Dental interlock controls this phenomenon. 3. Complete dentition in dogs consists of 42 teeth. Acceptance of missing dentition leads to having this problem established in the population. 4. The cause of persistent deciduous teeth may be their malposition as well as malocclusion of permanent teeth during eruption.. 5. Until the somatic development of the animal is completed changes in occlusion may be observed. The final reliable evaluation of occlusion is performed at an appropriate age (usually 9-10 months in small, 10-12 months in medium, and 12-14 months in large breeds).. 6. ...
Pain during chewing, yawning or laughing may indicate problems of the musculature and temporo-mandibular joint (the joint between the lower jaw and the skull). If severe problem in these areas exists, you may need to see an oral surgeon.. Orthodontic treatment (concerned with movement of teeth) could help bring the teeth into a proper occlusal relationship, and may have to be involved in full mouth restoration.. The evolving trend of dental tourism encourages patients to travel for cheaper procedures and get treated in the best possible manner. Full mouth restoration is an expensive desire to fulfill for many but due to the emergence of modern dental clinics offering costly procedures like Straumann teeth implants and Zimmer teeth implants in Thailand, Mexico or India at a price unheard of in developed nations like the US or the UK, patients are encouraged to cover huge distances to get that happy curve on their faces.. ...
Ball And Socket Joints: Example- The hip joints. Before we can begin to unravel the nature of this disorder, let us take a quick look at what the Temporomandibular Joint is , and where it can be found within your body. The Temporomandibular Joint belongs to Hinge Joint category. This is the joint that connects the lower jaw to the upper jaw. This joint is of vital importance to the body, as it enables the opening and closing of the mouth. Functions like eating and talking, and even yawning, are possible thanks to the smooth working of this joint.. However, as is the case with any part of our body, this joint too can suffer damage, and not work as smoothly as it once did. This disorder often occurs as the outcome of a damaged jaw or joint from an accident , or as a result of sustaining an injury, like a whiplash, on the muscles of your head and neck. Another probable cause is the onset of Arthritis. This is a highly painful disorder, and it can last for any amount of time-period, ranging from ...
