Abstract
Recording centric and protrusive jaw relations in completely edentulous patients remain a critical yet challenging step in complete denture fabrication. Therefore, it is of interest to compare the consistency of jaw relation records obtained using Nick and Notch, intraoral Gothic arch tracing and extraoral Gothic arch tracing methods with split-cast mounting on a semi-adjustable articulator. Hence, twenty edentulous subjects (45–60 years) were evaluated and discrepancies were measured at right lateral, left lateral and anterior points using a digital Vernier caliper. Statistical analysis using one-way ANOVA and Tukey’s post hoc test demonstrated that the Nick and Notch technique exhibited the least discrepancy, while extraoral Gothic arch tracing showed the highest inconsistency, with intraoral tracing demonstrating intermediate values. The Nick and Notch technique was found to provide the most reliable jaw relation records, with intraoral Gothic arch tracing being more accurate than extraoral tracing, likely due to reduced muscular interference and closer approximation to the condylar rotational axis.
