We report alteration of the temporomandibular joint disk and the condyle position through the construction of a mandibular full-coverage occlusal appliance (often referred to as a disk repositioning appliance).
Forty-five joints with displaced disks with reduction were available for the study. We assessed these joints for disk recapture and the change of disk position with insertion of the appliance using magnetic resonance imaging.
Of the 41 joints that had a recaptured disk with insertion of the splint, 25 slid in a posterior direction, although the amount of movement was negligible. No disk slid posteriorly in the joints without splint capture.
On the basis of our results, we conclude that many of the occasionally displaced disks might have moved backward with successful treatment involving a disk-repositioning splint. However, the amount of the movement was negligible.
我们通过制作下颌全覆盖咬合矫治器（通常称为盘复位矫治器）来报告颞下颌关节盘和髁突位置的改变。
本研究纳入了45个可复性盘移位关节。我们使用磁共振成像评估这些关节在矫治器插入时盘的复位情况及盘位置的变化。
在插入夹板后盘复位的41个关节中，25个向后滑动，尽管移动量可忽略不计。在未用夹板复位的关节中，没有盘向后滑动。
基于我们的结果，我们得出结论，许多偶尔移位的盘在采用盘复位夹板的成功治疗中可能向后移动。然而，移动量可忽略不计。
