Repeatability of the centric jaw relation recorded with the one-handed push-back technique was tested on six subjects. Condylar positions were radiographically recorded using cold cure acrylic indices to lock the jaws in centric. This was done on two occasions with an interval of 1 week between recordings. Utilizing the subtraction technique, the radiographs of these condylar positions were compared. Intra-individual differences were not found to be significant and it may be concluded that centric relation registered with the push-back technique results in accurate and consistent repositioning of the condyles in the glenoid fossa.
采用单手后推技术记录的正中颌位关系的重复性,在6名受试者身上进行了测试。使用冷固化丙烯酸树脂指标通过放射成像记录髁突位置,以将颌骨锁定在正中位。在两次记录之间间隔1周的情况下进行了两次这样的操作。利用减法技术,对这些髁突位置的X线片进行了比较。未发现个体内差异具有显著性,因此可以得出结论,采用后推技术记录的正中关系可使髁突在关节窝中实现准确且一致的重新定位。
