Background: Studies of mandibular movement trajectories have provided a good understanding of the motion of the condyle but little information on the geometric relationships of the disc because they have not related the movements to anatomic structures. Objective: This study investigated the morphology and kinematic characteristics of the Temporomandibular Joint (TMJ) using Cine-MRI and ARCUSdigma systems. Methods: For this study population, preliminary clinical diagnoses were asymptomatic in 15 cases, unilateral anterior disc displacement with reduction (ADDWR) in 17 cases, and unilateral Anterior Disc Displacement Without Reduction (ADDWoR) in 14 cases. Patients were investigated with Cine-MRI and ARCUSdigma systems during physiological opening and closing of the mouth. Results: In these groups, there were 13 healthy subjects, 19 patients with unilateral ADDWR and 14 patients with unilateral ADDWoR classified by Cine-MRI. (1) To assess morphology by MRI, disc deformities were evaluated as follows: biplanar, rounded, thickening in the posterior band, lengthened and folded. (2) The opening trajectory for healthy subjects was close to the closing trajectory. Conversely, the incisal and condylar trajectories during opening and closing were obviously bounced, deviated or shortened in the ADDWR and ADDWoR groups. The pathway of the kinematic axis was not parallel, and the condylar trajectory had an inflexion. (3) The mean values of the incisal and condylar paths of the ADDWoR group were significantly different from those in the healthy group (P<0.05), whereas there were no significant differences between the ADDWR and the healthy group (P>0.05). Conclusion: This study combined analysis of the condylar pathways and disc-condylar relationship to provide good visualization of morphology and kinematics during jaw movement. This process helps improve our understanding of the complexity of disk-condylar movements in subjects with TMJ internal derangement and may also contribute to our knowledge of the etiology of TMJ internal derangement.

“…For this instance, new sequences were started to apply especially for bone marrow and inflammatory changes of TMJ in different studies. Several studies used frequency-selective fat-suppressed (FS) T2W sequence and found it to be more sensitive than fast spin-echo (FSE) T2W images in detecting marrow alterations and stated to be used instead of FSE T2W images [ 15 – 17 ] while the others used several sequences such as half-Fourier acquisition single-shot turbo spin-echo (HASTE) [ 18 – 20 ], fast low-angle shot (FLASH) [ 21 , 22 ], steady-state free precession (SSFP) (true fast imaging with steady-state precession (true FISP) [ 23 ], balanced fast field echo (bFFE), balanced turbo field echo (bTFE), and fast imaging employing steady-state acquisition sequence (FIESTA) [ 24 ] especially for dynamic imaging of TMJ.…”

“…3D FIESTA sequence is an ultrafast pulse sequence and used for imaging of small structures such as cranial nerves (trigeminal neuralgia) [ 25 ], internal auditory canal [ 26 ], middle ear, or joints [ 24 ] in the literature. 3D FIESTA and FIESTA-C combine 3D volumetric data acquisition with fluid-sensitive steady-state imaging which adds phase cycling to the excitation pulse to minimize the build-up of artifacts in the residual transverse magnetization [ 24 – 26 ].…”

Aim. Osteonecrosis can affect the mandibular condyle, and bone marrow edema may be a precursor in osteonecrosis development in temporomandibular disorder (TMD) patients. Early detection of bone marrow changes is crucial for occurring osteonecrosis. The purpose of this study was to compare the diagnostic value of fast spin-echo T2 weighted (FSE-T2W), fat-suppressed T2W (FS-T2W), and three-dimensional (3D) fast imaging employing steady-state acquisition (FIESTA-C) MR sequences for early detection of bone marrow changes as well as TMJ soft tissue alterations. Methods. A total of 60 joints with TMD were included in this study using a 1.5T MR machine (Signa HDxt, GE, Milwaukee, USA) using a dual surface TMJ coil. Qualitatively, the images were interpreted by two observers for disk configuration, disk position, joint fluid, and bone marrow changes. Quantitatively, signal intensity ratios (SIR) in the TMJ condyle, retrodiscal tissue, disk, and muscle were also measured using all tested sequences. Kappa coefficients were calculated to assess both intra- and interobserver agreements for each image set. The SIR of each sequence was compared using a one-way ANOVA Bonferroni-Dunn test. Results. Overall intraobserver kappa coefficients ranged between 0.35 and 0.88 for joint fluid and between 0.22 and 0.82 for bone marrow changes diagnosis, suggesting high intraobserver agreement for FS-T2W and 3D FIESTA-C sequences than FSE T2W sequence ( p < 0.05 ). 3D FIESTA-C showed higher agreement values for disk configuration and position detection than other sequences. Conclusions. 3D FIESTA-C sequences can be used and incorporated into routine MRI protocols for obtaining high-resolution TMJ MR images due to the short acquisition time and 3D nature of the sequence. Additional studies should be done for dynamic TMJ imaging with this sequence.

“…Previous studies have focused on recording kinematic trajectories by a variety of approaches 7,8 such as dynamic magnetic resonance imagining (MRI). Dynamic MRI produces an accurate and intuitive view for capturing the motion of TMJs, 9,10 but the frequency is too low. Electronic-magnetic motion analysis systems can depict the trajectories of designated points, including the middle of condyles and lower incisor points during a motion, 11,12 but all test subjects share the same condylar distance, which disagrees with reality.…”

Temporomandibular joints (TMJs) constitute a pair of joints that connect the jawbone to the skull. TMJs are bilateral joints which work as one unit in conducting daily functions such as speaking, mastication, and other activities associated with the movement of the jaw. Issues associated with the TMJs may arise due to various factors—one such factor being the internal load on the TMJ. These issues may contribute to temporomandibular disorders (TMD). This study aims to evaluate the mandibular trajectories and the associated stress changes during the process of opening the mouth on the TMJs of an asymptomatic subject. The mouth opening motion was recorded by a motion capturing system using models of the mandible and maxilla constructed based on the computed tomography (CT). Two discs constructed based on magnetic resonance imaging (MRI). Finite element analysis was performed on the relative motion of the mandible to the maxilla and validated. The process modelled by these displacements provided less than 10% error in terms of deformation. The simulation results indicate that the lateral intermediate zone—the head and neck of the mandible—and the articular eminence sustained the most significant stresses during the mouth opening motion. The results also suggested that the stresses increase as the range of opening increases with the greatest von Mises stress, tensile, and compressive stress found at the position of maximal opening.
