Repeatability of the mandibular retruded position

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.
