“…In a previous study, the loss of posterior teeth was accompanied by a significant decrease in the height of the condyle and an increase in the width of the condyle without alteration in its total volume (15). Some studies have investigated the morphological and morphometric relationship of TMJs with disc displacement using MRI (5,8,10,40,41). MRI is the gold standard for evidencing structural changes, especially in the soft tissues of the TMJ as it can detect the articular disc (8).…”

The temporomandibular joint (TMJ) is a synovial joint classified for its surface shape and complex biaxial movements as a ginglimoartrodial joint and presents the widest joint range of movements when compared with the other joints of the human body. The complexity of TMJ morphology has driven researchers to investigate its morphometric features and their relationship with temporomandibular disorders (TMD). Therefore, the knowledge of morphological and morphometric data of each bone component of the TMJ is of paramount importance for identifying bone changes related to the TMJ, in the presence of TMD in symptomatic and non-symptomatic patients. This literature review aims to assess previous studies on the TMJ bone structures morphological and morphometric findings and discuss what these findings implicate on TMDs. The assessed studies varied in sample size and categorization, and measurement methodologies [measurements done directly on specimen, image modality-computed tomography (CT), cone beam computed tomography (CBCT), magnetic resonance imaging (MRI)], study method of choice and main morphometric points). Morphometric measurements of the condyle, articular fossa and articular eminence were assessed in different planes (axial, sagittal and coronal). Male patients present higher condyle and glenoid fossa morphometric measurement values than female patients, however, when considering the articular eminence's inclination/steepness the gender difference is not conclusive. When more than one image method was assessed, a slight difference has been observed between the image modalities. It can be concluded that large, paired samples and longitudinal studies using non-ionizing images are still needed to assess the TMJ morphometric values and its association with internal disorders, age, ethnicity, and gender.

“…Most often the temporomandibular joint current MR images are obtained using 1.5-T MRI systems [31][32][33][34][35][36][37][38]. Manoliu et al [38] quantitatively and qualitatively compared MRI images of TMJ using two different protocols at 1.5 T and at 3.0 T. According to the authors, imaging at 3.0 T is recommended because of significantly better quality, visibility and delineation of anatomical structures, including articular disc and masticatory muscles.…”

Interdisciplinary Approach to the Temporomandibular Joint Osteoarthritis—Review of the Literature

2020

Background and objectives: There is an increasing number of patients applying for dental treatment who suffer from temporomandibular joint osteoarthritis (TMJOA). Osteoarthritis may be the cause of the pain in the area of temporomandibular joints, but its course may also be absolutely asymptomatic. The aim of this study was to present an interdisciplinary approach to TMJOA, including current diagnostics and treatment modalities on the basis of the available literature. Materials and Methods: PubMed and Scopus databases were analyzed using the keywords: ((temporomandibular joint AND osteoarthritis) AND imaging) and ((temporomandibular joint AND osteoarthritis) AND treatment). The bibliography was supplemented with books related to the temporomandibular joint. After screening 2450 results, the work was based in total on 98 publications. Results and Conclusions: Osteoarthritis is an inflammatory, age-related, chronic and progressive degenerative joint disease. Magnetic resonance imaging (MRI) and cone-beam computed tomography (CBCT), together with clinical symptoms, play significant roles in TMJOA diagnosis. Current MRI techniques seem to be clinically useful for assessment of bony changes in temporomandibular joint (TMJ) disorders. Treatment of TMJOA requires a complex, interdisciplinary approach. TMJOA treatment includes the cooperation of physiotherapists, rheumatologists, gnathologists, orthodontists and quite often also maxillofacial surgeons and prosthodontists. Sometimes additional pharmacotherapy is indicated. Thorough examination of TMJ function and morphology is necessary at the beginning of any orthodontic or dental treatment. Undiagnosed TMJ dysfunction may cause further problems with the entire masticatory system, including joints, muscles and teeth.

“…In the authors' opinion, patients' adaptability and susceptibility to pain were responsible for the uncommon results. Rabelo et al [30] found the association between anterior disc displacement and an increased size of anterior joint space. Almasan et al [24] noticed that, in cases with anterior disc displacement with reduction compared to the group with the normal position of the disk, only anterior joint space was significantly larger.…”

Background: Patients referred for orthodontic treatment often present symptoms of temporomandibular joints’ disorders (TMD), predominantly clicking. The objective was to analyze the morphology of the temporomandibular joints in cone-beam computed tomography (CBCT) images based on the presence of reciprocal clicking before orthodontic treatment. Methods: 105 participants took part in the study. 210 temporomandibular joints (TMJs) were allocated into one of two groups regarding the presence of reciprocal clicking. Morphology of condyle’s head, glenoid fossa, and articular eminence as well as condylar head position in the glenoid fossa and osteoarthritic changes in the area of the condylar head were examined for each TMJ in the CBCT images. Statistical analysis was performed with STATISTICA version 12.0. The following tests were performed: U-Mann Whitney, Kruskal-Wallis, t-Student, and chi-square. The statistical significance level was p = 0.05 for all the measurements included. Results: Significantly smaller condylar A-P dimension (p = 0.040) characterized temporomandibular joints with reciprocal clicking. Condyles were substantially more often positioned posteriorly (p = 0.043) and were significantly more often accompanied by subcortical cysts and pathologic osteoarthritic bone changes (p < 0.001). Conclusions: The early stages of internal derangements stay with alterations in morphology and position of TMJs as well as with the presence of osteoarthritic changes.
