“…28 In the present patients the prevalence of TMJ clicking was 11% (3/28 TMJs) at T3 and 25% (7/28 TMJs) at T4 (Table 3), and was thus of the same magnitude as that found in subjects representing normal populations. 22,30,31 Summarizing our results, there was no indication that any of the long-term follow-up findings on TMJ disorders were related to Herbst therapy.…”

Objective: To analyze radiographic signs of temperomandibular joint (TMJ) osteoarthritis and clinical TMJ symptoms in patients 6 years and 32 years after treatment with a Herbst appliance. Materials and Methods: Fourteen patients were derived from a sample of 22 with Class II division 1 malocclusions consecutively treated with a banded Herbst appliance at the age of 12-14 years old (T1-T2). The subjects were reexamined after therapy at the ages of 20 years (T3) and 46 years (T4). The TMJs of the 14 patients were analyzed radiographically (conventional lateral tomography at T3 and cone-beam computed tomography at T4) and clinically/anamnestically at T3 and T4. Results: Six years after Herbst therapy, signs of osteoarthritis were seen in one patient. At the 32-year follow-up, two additional patients had developed signs of osteoarthritis. At the 6-year followup, TMJ clicking was present in two patients, though none of the patients reported TMJ pain. At the 32-year follow-up, six patients had TMJ clicking and one patient had TMJ pain. Conclusions: This longitudinal very-long-term follow-up study after Herbst therapy revealed only minor problems from the TMJ. The TMJ findings 6 years and 32 years after Herbst treatment corresponded to those in the general population. Thus, in the very long term, the Herbst appliance does not appear to be harmful to the TMJ. (Angle Orthod. 2015;85:735-742.)

“…These measurements can only be used if the disc is displaced in an antero-lateral direction. According to different studies, antero-lateral disc displacement is less frequent than antero-medial disc displacement [13,15,17]. We have not compared our results with the studies that have used only static high-resolution US.…”

High-resolution ultrasonography in assessing temporomandibular joint disc position

et al. 2018

Aims: The purpose of this study was to determine the diagnostic value of high-resolution ultrasonography (US) in temporomandibular joint (TMJ) disc displacements.Materials and methods: A number of 74 patients (148 TMJs) with signs and symptoms of TMJ disorders, according to the Research Diagnostic Criteria for Temporomandibular Disorders, were included in this study. All patients received US and magnetic resonance imaging (MRI) of both TMJs 1 to 5 days after the clinical examination. MRI examinations were performed using 1.5 T MRI equipment (Siemens Avanto, Siemens, Erlangen). Ultrasonographic examination was performed on a Hitachi EUB 8500 (Hitachi Medical Corp., Tokyo, Japan) scanner with L 54 M6.5-13 MHz linear transducer.Results: MRI depicted 68 (45.95%) normal joints, 47 (31.76%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 34 (22.97%) with degenerative changes. US detected 78 (52.7%) normal joints, 37 (25%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 21 (14.19%) with degenerative changes. Compared to MRI, US showed a sensitivity of 93.1%, specificity of 87.88%, accuracy of 90.32%, a positive predictive value of 87.1% and a negative predictive value of 93.55% for overall diagnosis of disc displacement. The Youden index was 0.81.Conclusions: Based on our results, high-resolution ultrasonography showed high sensitivity, specificity and accuracy in the diagnosis of TMJ disc displacement. It could be a valuable imaging technique in assessing TMJ disc position. The diagnostic value of high-resolution ultrasonography depends strictly on the examiner’s skills and on the equipment used.

“…The TMJ can be affected by osteoarthritis, rheumatologic diseases, gout, luxation, ankyloses, benign or malignant tumors, and infections. TMJ internal derangement, defined as when the disk is improperly positioned in relation to the condylar-fossa complex, affects between 7.9% and 44% of the population, although few affected individuals develop clinical symptoms requiring medical attention [8][9][10][11].…”

A disease-focused view on the temporomandibular joint using a Delphi-guided process

et al. 2020

View full text Add to dashboard Cite

Temporomandibular joint (TMJ) disease classification and subsequent treatment selection are highly debated subjects within dentistry and medicine. Several suggestions for diagnostic classification and treatment algorithms have been proposed thus far without achieving a clear gold standard. A universally accepted diagnostic classification is essential for therapeutic decision-making as well as a prerequisite for prognostic evaluation and is necessary for achieving research results that are reproducible, comparable, relevant, and applicable in the clinical setting. Often, problems of the TMJ are viewed as mere symptoms or as a syndrome-like group of conditions, without clear demarcation, impeding individualized treatment planning. A Scandinavian group of experienced TMJ surgeons participated in an iterative, structured group discussion process in accordance with the Delphi method, aiming to produce recommendations for a standardized patient clinical evaluation in relation to TMJ dysfunction. Guided by this standardized evaluation, a disease-focused and simplified diagnostic classification scheme is herein suggested.

Temporomandibular Joints in Asymptomatic and Symptomatic Nonpatient Volunteers: A Prospective 15-year Follow-up Clinical and MR Imaging Study

Abstract: Volunteers with mild symptoms had a prevalence of disk displacement of the same magnitude as that reported in patients, although most volunteers, symptomatic as well as asymptomatic, maintained their TMJ status during 15 years.
