Comparative Analysis of Sagittal Condylar Guidance Recorded by Intraoral Gothic Arch Tracing and Panoramic Radiograph in Completely Edentulous Patients

Abstract

To compare the intraoral gothic tracing method with panoramic radiographs in patients requiring complete dentures. The present study was conducted on 20 edentulous subjects of both genders. Hanau Wide-Vue semi-adjustable articulator was used to record sagittal condylar guidance in all patients. Panoramic radiographs were taken in all patients and Frankfurt horizontal plane was traced on both sides of orthopantomogram (OPG) and second plane was marked by joining the most superior and most inferior point on the glenoid fossa curvature. Frankfort's horizontal plane was crossed with this line to record radiographic condylar guidance angle. NNT software was used to record the condylar guidance angle. Mean ± standard deviation (SD) clinical SCG (25.15 ± 3.24) and radiographic seismocardiography (SCG) (27.54± 5.01) was non significant (p > 0.05) on left side. Mean ± standard deviation (SD) clinical SCG (26.84 ± 3.69) and radiographic SCG (29.3 5 ± 4.58) was significant (p < 0.05) on right side. The SCG did not show difference in values recorded by both methods on both sides. The difference in values in both sides by clinical method and radiographic method was non-significant (p > 0.05). There was correlation between sagittal condylar guidance obtained by both intraoral gothic arch method as well as radiographic method done on digital panoramic radiographs. Correct centric jaw relation determines the success of the complete denture. Radiographic and clinical methods provide sufficient minute details necessary for the betterment of management.
