Revising Average Condylar Inclinations Using Electronic Pantograph Assessment: A Cross-Sectional Study

Abstract

Introduction: Condylar inclinations produce a frame for the occlusal morphology of dental restorations. Applying arbitrary average values for the articulator settings has brought about more practicality to the prosthesis fabrication procedures. The present study aimed at determining the average sagittal condylar inclination (SCI) and Bennett angle (BA) using electronic pantograph and comparing the inclination quantities obtained from different methods to proposed average measurements. Materials and Methods: Using Cadiax Compact II, condylar inclinations were recorded in 50 participants, generally healthy without any signs of joint problems. The recorded average values were compared with proposed mean values using one sample t-test. The level of significance was set at P < 0.05. The available articles were also searched using electronic databases. Results: A statistically significant difference was observed in the mean SCI (41.66°) and the proposed average value (33°) (P < 0.05). The difference between BA mean value (10.10) and arbitrary proposed value (15) was even more pronounced (P < 0.05). Pantographic records show different values compared to average propositions for condylar inclinations. Conclusion: Ongoing controversies concerning the average values for articulator settings proposed a revision in traditionally used arbitrary settings as well as Hanau formulation on the sagittal and lateral inclination interrelationships.
