| Objective: The protrusive record is one of the most important records created in prosthodontic rehabilitation, as well as management of temporomandibular joint disorder or sleep apnea, or maxillofacial rehabilitation. The aim of this study to evaluate the accuracy of George gauge in protrusive records. Methods and Material: This clinical trial includes a total of 12 dentulous subjects aged 20 to 40 years with no signs of muscular disease or temporomandibular joint disorders were chosen. For each patient, two different protrusive records were created, one with and one without the George gauge, using polyvinyl siloxane materials. The accuracy of these two protrusive records was evaluated through measuring the amount of midline shift in both records with a digital calliper. Then these Protrusive records were used to programme the articulator and determine the specific horizontal condylar angle (HCI) value, as well as panoramic radiographs to compare clinical and radiographic values. Paired sample t- test, and ONE WAY ANOVA test was used for parametric data analysis. SPSS Ver.23 was used for statistical analysis. Results: The findings revealed a statistically significant difference in the accuracy of the protrusive record when done conventionally versus with the aids of George Gauge, with George Gauge providing a more accurate record. The angle obtained via panoramic radiographs was steeper than the angle obtained clinically. Conclusions: The George gauge aids in accurate and simple registration of protrusive records. The condylar guidance angles determined by radiographs were greater than those determined by clinical methods using protrusive records. | ||||
