Spatial analysis of condyle position according to sagittal skeletal relationship, assessed by cone beam computed tomography

One of the temporomandibular joint disorders that mostly occurs is disc displacement with reduction. Disc displacement that causes the displacement of condyle position can be evaluated by using radiograph. The Cone Beam Computed Tomography (CBCT-3D) is a radiograph equipment which is able to capture the condyle position from many directions. This research was aimed to see the condyle position in patients with disc displacement with reduction symptoms. This research was conducted to 11 patients with symptoms of disc displacement with reduction and 3 patients without symptoms of disc displacement with reduction as the counterpart. What was conducted to the sample was the radiographic imaging using CBCT-3D radiography, followed by measuring the joint space distance in the sagittal and coronal directions. The result of the research was analyzed using the T-test. Statistically, the result of the test showed a significant difference ( = 0.05) between patients with disc displacement with reduction symptoms and the patients without symptoms, in sagittal and coronal views. The conclusion led to the difference in condyle positions in patients with the disc displacement with reduction and patients without the symptoms which meant there was a condyle position displacement that caused the distance alteration in joint space in sagittal and coronal directions.

<p>ABSTRACT: The aim of the study was to investigate the condylar position within the articular cavity in patients with temporomandibular disorders with signs and symptoms of functional articular disorders through images made with cone beam computed tomography (CBCT) on the sagittal plane. Methods: CBCT temporomandibular joints images of 62 patients (13 men and 49 women, average age, 39.7 years) with signs and symptoms intra-articular diagnosed by the Craniomandibular index were analyzed using the measurement method recommended by Kawamura and Ikeda (2009). We obtained the linear measures of posterior space (PS), superior space (SS), and the anterior space (AS) to determine the condyle position for each joint. Results: The average of the measurements of PS, SS, were respectively 1.9 mm (DP 0.5), 3.1 mm (DP 0.9), and 2.0 mm (DP 1.0). Conclusion: This study found that the subjects with intra-articular TMD when compared with the excellent condylar relationship established by Ikeda and Kawamura (2009) presented a more posterior and inferior condylar position.</p>

In this article, we evaluate the effectiveness of Cone Beam Computed Tomography, through a case study, in assessing the complication of intracranial bleeding during an endovascular treatment of brain arteriovenous malformation when compared to Multislice-Detector Computed Tomography performed immediately after the procedure. The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.
