Abstract

|
|
The purpose of this study was to compare the replicability of centric relation made by means of self guided method, bimanual manipulation, chin-point guidance, leaf gauge method, gothic arch tracing. The EPA test of Arcus Digmaⓡ was employed for examining the reproducibility of centric relation. 10 adults with normal occlusion were participated in this study. In this limitation of study, the following results were obtained; Condyle position was different depending on different methods of guiding centric relation . Left and right temporomandibular joints showed a little different degree of repeatability. Bimanual manipulation using anterior jig was the most replicable. Chin point guidance provided the second most repeatable method, and Gothic arch tracing showed the third, the leaf gauge was the forth , the self-guided method was the worst.
