“…Regarding the type of disc displacement, the proportion of patients with DDWoR was higher than that of those with DDWR (20.6% vs. 14.2%). This is consistent with the findings of previous studies ( 4 , 21 ) . However, a study involving 218 symptomatic TMD patients showed a higher incidence of DDWR ( 5 ) , perhaps because the most common age group was 16-25 years (accounting for 37% of the sample), constituting a younger population than that evaluated in the present study, given that DDWR is more common in younger patients and represents the initial stage of TMJ abnormalities.…”

“…Clinical examination is insufficient to diagnose TMJ changes ( 1 ) . MRI is the best method for diagnosing TMD; in addition to providing excellent routine static images, it has the ability to analyze disc position and condylar excursion throughout the dynamic process of mouth opening and closing by obtaining multiple static images in series ( 2 , 21 ) .…”

Objective: To assess changes in the articular surfaces of the temporomandibular joint (TMJ) and in condylar translation, as detected by magnetic resonance imaging (MRI), determining whether such changes correlate with disc displacement. Materials and Methods: We retrospectively analyzed the MRI scans of 2076 TMJs of 1038 patients with symptoms of temporomandibular disorder. We attempted to determine whether articular disc deformity and changes in condylar translation, as well as changes in the articular surfaces of the condyle, glenoid fossa, and articular eminence, correlated with disc displacement. Results: Disc displacement with reduction was associated with changes in the shape of the articular eminence. Disc displacement without reduction was most strongly associated with disc deformity, condylar degeneration, glenoid fossa degeneration, and effusion. Neither decreases nor increases in condylar translation were associated with disc deformity, degenerative bone changes, or disc displacement. Conclusion: Changes in the shape of the articular eminence seem to predispose to progression of internal derangement of the TMJ.

“…For imaging evaluation of the TMJ, the MRI is considered the gold standard, since it allows obtaining soft tissue images of excellent contrast and has the advantage of being a free ionising radiation test 14‐16 . While computerised tomography (CT) is considered the most accurate of traditional radiographic techniques to obtain images of TMJ and evaluate hard tissues, 17 recently, conical beam CT (CBCT) has been developed as an alternative to conventional CT for dental and maxillofacial diagnosis, with the benefit of lower ionising radiation for the patient 18 .…”

The temporomandibular joint (TMJ) is part of the craniofacial complex and is made up of a large number of structures and elements, making its operation complex, so that small alterations can cause a wide variety of functional problems. 1. These problems are known as temporomandibular disorders (TMD), a generic term covering a group of musculoskeletal and neuromuscular conditions that affect the TMJ, the masticatory muscles and all associated tissues. 2,3 AbstractTemporomandibular joint disc displacement is common in the world's population and could be associated with bone and functional characteristics of the temporomandibular joint. The aim of these study was to analyse the association between temporomandibular joint disc position evaluated by magnetic resonance imaging (MRI) and the inclination of the mandibular condyle evaluated by computed tomography (CT).One hundred and seventy temporomandibular joints (TMJ) were retrospectively analysed. The temporomandibular disc position was evaluated by MRI and classified into three types: normal (N), disc displacement with reduction (DDWR) and disc displacement without reduction (DDWoR). The mandibular condyle measurements evaluated by CT included horizontal, sagittal and coronal inclination. ANOVA followed by post hoc Tukey's test was used to evaluate the interaction between condylar inclination and disc position. There was an association between disc position and the horizontal and sagittal condylar inclination (P < .05). There are statistically significant differences in the mean of horizontal and sagittal inclination of the mandibular condyle between the DDWoR and the other disc positions (P = .002 and P = .004). Disc position was not statistical associated with coronal inclination of condyle (P > .05). These results indicate that the inclination of the mandibular condyle may be different in TMJ with various disc position. A more medial horizontal inclination and a more posterior sagittal inclination of the mandibular condyle are associated with DDWoR. K E Y W O R D Scomputed tomography, magnetic resonance imaging, mandibular condyle, temporomandibular joint, temporomandibular joint disc |The TMD are a major health problem, affecting more than 50% of the world's population at some point in their lives and usually occurs in children, youth and adults of all ages and gender. 4,5 TMD can be classified into two major categories: temporomandibular joint disorders and masticatory muscle disorders. 2,3 Among the disorders of the TMJ are the alterations of the intra-articular mobility and the disorders of the disc-condyle complex. 2,6 Disorders of the disc-condyle complex consist of an abnormal position of the articular disc with respect to the mandibular condyle and the articular eminence. [7][8][9] Abnormal disc position or disc displacement has often been diagnosed in patients of diverse populations and can occur even in the growing population and is considered to be a condition that may worsen over time. 10,11 It has been observed that disc displacement of the TMJ is ab...

Temporomandibular joint disorder (TMJ) is a complex and multifactorial functional disorder. Best approach in the treatment of TMJ disorders needs in detail proper diagnostic study. Joint vibration analysis (JVA) device, a new age technology and one of the most important diagnostic tools, is used for detecting intra-articular sound vibrations. Every type of vibration in different frequencies shows us the status of joint. Evaluation can be made after analyzing the results applying to a diagram. Like Combining of the sound vibration diagnostic techniques with other examination methods may be very meaningful in efforts of treating TMJ problems. Another diagnosis method is the evaluation of chewing movements. Best chewing efficiency is the most important purpose of masticatory system. Final product is a very important indicator for the efficiency of the mastication, and chewing pattern. T-Scan digital occlusal analyzing system is another important occlusal diagnostic instrument. Digital occlusal analysis system is currently the most powerful method of TMD clinics for treatment of patients with muscle pain dysfunction syndrome. Digital occlusal analysis system allows us to perform the MPDS treatments, splint and occlusal rehabilitation. The three important diagnostic systems are described in this chapter.
