This study was performed to investigate the pattern of condylar pressure distribution in the discs of a patient diagnosed with disc displacement without reduction.
This research consisted of a pre- and post-test observational clinical study. A patient diagnosed with disc displacement without reduction underwent treatment with an occlusal splint for 3 months. Finite element analysis employed a 3-dimensional model constructed from magnetic resonance images of the patient, taken both before the application of the splint and 3 months after its use.
The post-test model demonstrated a decrease in condylar pressure on the disc, with measurements dropping to 72 MPa from the pre-test level of 143 MPa. In the pre-test, the pressure distribution pattern was concentrated on the lateral posterior border, whereas in the post-test, it shifted toward the intermediate zone of the disc.
Utilization of a stabilization splint for 3 months resulted in decreased pressure and a marked change in the pressure distribution pattern on the temporomandibular disc.
本研究旨在调查一名被诊断为不可复性盘移位患者的髁突在关节盘中的压力分布模式。
本研究为一项前后测试的观察性临床研究。一名被诊断为不可复性盘移位的患者使用咬合板治疗3个月。有限元分析采用从患者的磁共振图像构建的三维模型，这些图像在使用咬合板之前和使用后3个月拍摄。
测试后模型显示髁突在关节盘上的压力降低，测量值从测试前的143MPa降至72MPa。在测试前，压力分布模式集中在外侧后缘，而在测试后，它向关节盘的中间区域转移。
使用稳定咬合板3个月导致颞下颌关节盘上的压力降低以及压力分布模式发生显著变化。
