A Comparative Evaluation of Sagittal Condylar Guidance Between Dentate and Edentulous Patients Using CBCT: An in Vivo Study

Objective: The purpose of this study was to compare the sagittal condylar guidance (SCG) angle between dentate and edentulous patients, right and left sides, and males and females. At the same time, the study aimed to explore any statistically significant relation in values of the (SCG) angles between different age groups. Methods: The study samples included 40 participants, 20 dentate patients (10 men and 10 women, aged from 20-49 years) were included. Similarly, 20 edentulous patients (10 men and 10 women, aged from 50-79 years) were taken on. (SCG) angles were measured for the right and left sides using (CBCT) with appropriate software. Independent samples t-test and ANOVA test were used to analyze the data. Results: The difference in (SCG) values between dentate and edentulous patients was statistically significant at p < 0.05. In contrast, the recorded values of (SCG) were comparable between the right and left sides, between males and females, with no statistical differences, p > 0.05. Furthermore, potential statistically significant differences between the values of SCG angles and different age groups in dentate and edentulous cases were not explored. Conclusions: There was no significant variation in the values of the SCG angles between the right and left sides simultaneously between males and females. However, a significant difference was detected in the value of SCG angles between dentate and edentulous cases. In contrast, statistically significant differences were not depicted in the values of SCG angles between different age groups in dentate and edentulous samples.
