[HIRANUMA-13] Comparative analysis of sagittal condylar guidance by using Protrusive Interocclusal Record and Cone Beam Computed Tomography
[Abstract]
Summary:
Background: Accurate simulation of the condyle-articular disc pathway and eminence slope is crucial for prosthodontics prognosis, as inaccuracies can lead to unstable occlusions and time-consuming clinical steps, and accurate radiographic methods could avoid these issues.
Objective:
To compare the sagittal condylar guidance by using Protrusive Interocclusal Records and Cone Beam Computed Tomography.
Materials and methods: The study was conducted in the Department of Prosthodontics of BSMMU from March 2021 to September 2023. Patients were enrolled and a cone beam computed tomography scan was obtained. The sagittal condylar guidance angle was measured using software and a protrusive interocclusal record was created using polyvinyl siloxane material.
Result: The study found no significant differences in Sagittal condylar guidance angles between protrusive interocclusal records and cone beam computed tomography. However, males had a higher SCG angle, which was significant in both methods. Age-wise distribution of SCG angle did not show a significant difference.
Conclusion: Cone beam computed tomography offers standardized, stable bone markers over clinical methods, reducing time and potential for inaccurate findings due to material instability, making it an ideal tool for programming semi-adjustable and fully adjustable articulators.
