The aim of this article is 3D analysis of the temporomandibular joint (TMJ) patient, who underwent surgery, during which the right TMJ was resected along with the ramus of mandible and consequently the joint was reconstructed with subtotal replacement. The main goal is to give a suitable formulation of mathematical model, which describes the changes of stresses in TMJ incurred after the surgery. The TMJ 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 geometry for the 3D models is taken from the CT scan date and its numerical solution is based on the theory of semi-coercive unilateral contact problems in linear elasticity. This article provides medical part with case report, discretion of treatment, than the methods of mathematical modeling and his possibilities are described and finally results are reported.

Anterior disc displacement without reduction (ADDwoR) is one of the most common types temporomandibular disorders (TMD), which is often characterized by joint pain, abnormal joint sounds, and limited mouth opening. Disc repositioning has been described as an effective method to reduce joint pain and improve range of motion. Yang's arthroscopic disc repositioning and suturing surgery has been reported to be the most stable technique with 95%-98% of success rate.

Musculoskeletal pain has a high prevalence of transition to chronic pain and/or persistence as chronic pain for years or even a lifetime. Possible mechanisms for the development of such pain states are often reflected in inflammatory or neuropathic processes involving, among others, cytokines and other molecules. Since biologics such as blockers of TNF or IL-6 can attenuate inflammation and pain in a subset of patients with rheumatoid arthritis, the question arises to what extent cytokines are involved in the generation of pain in human musculoskeletal diseases.

Metastases of the articular process, temporomandibular joint (TMJ), are rare findings. Their frequency is around 5% of patients with metastatic involvement of the mandible. The most common primary tumor is adenocarcinoma of the lung in women and adenocarcinoma of the prostate in men.

Background: Temporomandibular disorders (TMD) are a major cause of non-dental pain in the oral and facial regions.
Objective: This study aimed to determine the prevalence and severity of TMD and anxiety among academics and to investigate the relationship between TMD and its associated factors.
Design And Setting: This cross-sectional study included a sample of 295 academics undertaking health courses at a university in Brazil.

Background: Adolescent females have a high prevalence of temporomandibular joint (TMJ) anterior disc displacement (ADD), which can lead to condylar resorption and dentofacial deformity. Polycystic ovarian syndrome (PCOS) is a common endocrine disorder that disrupts bone metabolism. However, the effects of PCOS on bone remodeling especially after disc repositioning (DR) surgery are not well understood.
