Analytical Approaches

The temporomandibular joint (TMJ) is a condylar synovial joint that, together with the masticatory muscles, controls mandibular movement during mastication. The rabbit is often used as a model species for studying the mechanisms of TMJ diseases, and in regenerative research. However, there are significant differences between rabbit and human TMJs that should be taken into account before using this model for experimental research. Here, we use several analytical approaches (radiography, computed tomography and magnetic resonance imaging) to enable a detailed description and analysis of the rabbit TMJ morphology. Moreover, possible surgical approaches have been introduced with a focus on available access into the rabbit TMJ cavity, which relate our findings to clinical usage.

Reduction Of Pain

Visualization of the temporomandibular joint (TMJ) is constantly evolving with the improvement of technology. Magnetic resonance imaging is commonly used to evaluate the TMJ due to the high contrast resolution and the ability to obtain dynamic images to demonstrate the functional capability of the joint. Aim - to determine the functional changes after TMJ splint therapy conducted at various stages of intra-articular disorders. Data and methods. We conducted a survey, clinical examination and MRI of TMJ of 37 patients with temporomandibular disorders (TMD). Two groups of patients were formed according to the received MR picture of TMJ. Results. The study highlighted that regression of pain in TMJ and masticatory muscles, and normalization of functional parameters after splint rehabilitation occur more often in the first group of patients, who have disorders of the articular disc of the TMJ. Conclusion. In both groups of patients we noted positive dynamics of functional parameters of TMJ, reduction of pain in TMJ and masticatory muscles. Though 36,8% of the second group of patients, who have bone remodeling of TMJ condyles, didn’t show dynamics of functional parameters. Consequently, the use of splint in one third of patients with temporomandibular joint condyles destruction is effective for TMJ and muscular pain reduction.

Therapy Strategies

Temporomandibular joint disorders (TMD) are a common health condition caused by the structural or functional disorders of masticatory muscles and the temporomandibular joint (TMJ). Abnormal mandibular movement in TMD patients may cause pain, chronic inflammation, and other discomfort, which could be relieved by a variety of drugs through various delivery systems. In this study, we summarized commonly used therapeutic agents in the management of TMD as well as novel bioactive molecules in preclinical stage and clinical trials. The emerging therapy strategies such as novel intra-TMJ delivery systems and implants based on tissue engineering are also discussed. This comprehensive review will strengthen our understanding of pharmacological approaches for TMD therapy.

This case report has the aim to present an adhesion of the temporomadibular disc to the articular eminence, diagnosed on magnetic resonance imaging images. A 37-year-old female patient with TMJ (temporomandibular joint) disk adhesion on the left side and complaining of bilateral otalgia over the last 2 years is reported in the present article. The patient did not complain of articular pain or clicking, or any other noises of any nature. Clinical observation showed that the patient had restricted jaw opening, with mandibular deviation the left side without correction during mandibular movement. Our diagnostic impression was of partial anterior disk displacement with reduction of the right side disc; and partial anterior disk displacement with reduction and disc disk adhesion with hypo-mobility of the condyle, on the left temporomandibular joint. The peculiarity of this reported case is the fact that besides the bilateral partial anterior disc displacement, there was also found an adhesion of the disc on the left side. In conclusion, the magnetic resonance imaging exam of the temporomandibular joint can be considered an exam of choice for the evaluation of disc positioning and its morphological alterations.

This article describes the methods of treatment of patients with osteoarthritis of the temporomandibular joint (TMJ OA) on the example of the study of 63 patients. Aim - development of an algorithm for complex treatment of patients with OA of the TMJ. Materials and methods. All patients were examined by the scheme, which included a survey, inspection, making diagnostic models, checking occlusal contacts, recording mandibular movement, electromyographic study of masticatory muscles, and CT scan of the TMJ. Results. All patients were divided into 3 groups. The treatment of patients of the first subgroup included selective polishing of the teeth, the use of non-narcotic analgesics, nonsteroidal anti-inflammatory preparations and physiotherapy The patients of the second subgroup received medical-diagnostic mouthguards, and the third subgroup of patients was treated by successive disocclusion of the teeth in combination with massage, physiotherapy and myogymnastics. Conclusions. Treatment of OA of the TMJ should be comprehensive and include orthopedic treatment, the use of drugs, physical therapy, massage and myogymnastics.

Relevant Role

Temporomandibular disorder (TMD) encompasses a set of disorders involving the masticatory muscles, the temporomandibular joint and associated structures. It is a complex biopsychosocial disorder with several triggering, predisposing and perpetuating factors. In the etiology of TMD, oral parafunctions, namely bruxism, play a relevant role. The study of bruxism is complicated by some taxonomic and diagnostic aspects that have prevented achieving an acceptable standardization of diagnosis. The aim of this study was to analyze the prevalence of temporomandibular disorders and bruxism in a Portuguese sample.
