Abstract


Background:  The aim of this study was to compare the horizontal condylar angles set in the Hanau articulator by use of intraoral protrusive record to those angles found using a panoramic radiographic image. Materials and Methods: Ten completely edentulous patients from either sex free of signs and symptoms of temporomandibular disorder were selected for in vivo study. For all patients, the protrusive records were obtained while doing extra oral gothic arch tracing and when the mandible moved forward by approximately 6 mm. The condylar guidance angles obtained were tabulated. A panoramic radiographic image of each patient was made and radiographically the angle was determined by cephalometric tracing Result: The comparison of mean condylar guidance angles between the right side of the protrusive record method and the right side of the panoramic radiographic method and the left side of the protrusive record method and left side of the panoramic radiographic method (p = 0.513and p = 0.118, respectively) were not statistically significant (p < 0.05) Conclusion: within the limit of this study, it was concluded that protrusive condylar guidance obtained by radiographic method can be used as an adjunct to protrusive method and error increases as if used independently to programme semi adjustable articulator.
