| Abstract | ||
| Introduction: Many techniques have been described in the literature for molding of the Neutral zone. Gothic arch tracer attached to neutral zone record used for accurate registration of centric relation. Material and method: This study was passed on 10 edentulous patients to compare the accuracy of centric relation using intra-oral Gothic arch tracer attached to two different neutral zone records. The first method includes, recording of neutral zone for each arch separately without vertical stopper then orientation of the occlusal plane on the articulator (indirect method), the other method record the neutral zone at predetermined vertical relation, using upstanding flange, then orient the occlusal plane intra- orally (direct method). Result: within this study, the indirect method of neutral zone exhibit a statistically more accuracy in registration of the centric relation using the Gothic arch tracer compared to the direct method. Conclusion: recording the neutral zone of each arch separately give more accurate registration of the centric relation than that using upstanding flange. | ||
