+The aim: To investigate the peculiarities of hinge axis trajectories in patients with condyle-disc complex intraarticular Temporomandibular Disorders (TMD) and determine the average coordinates of the reciprocal clicking location by axiography. Materials and methods: The results of axiographic examination of 151 patients (108 females and 43 males) with TMD confirmed by MRI were analyzed. This population included 44 persons with disc displacement with reduction (DDR), 45 persons with disc displacement with reduction and intermittent locking (DDRI), 62 persons with disc displacement without reduction (DDWR). Axiographic examination was carried out using CADIAX diagnostic device. Analysis of hinge axis movements was performed and the coordinates of articular disc reduction were determined. Results: The quality of hinge axis trajectories in persons with DDR, DDRI was defined mainly as average and in patients with DDWR as poor. Quantitative indicators of trajectories during protrusion-retrusion movements were not beyond the average level. The length of the mouth opening-closing trajectory in patients with DDRI and DDWR has shown a tendency to decrease. We found that on average the reciprocal closing clicking (disc reduction) occurs at a distance of 0-1.4 mm on the X-axis, 0.1-2.9 mm on the Z-axis, and 0-0.85 mm on the Y-axis. Conclusions: The obtained wide range of reciprocal clicking location parameters indicates the priority of a personalized approach when planning preliminary treatment in order to restore the disc-condylar complex of TMJ. |
