A study to evaluate the influence of condylar and incisal guidance in canine guided and group function occlusal schemes

Abstract

Aims: This study aimed to evaluate the combined influence of condylar and incisal guidance in canine-guided and group function occlusal schemes. Settings and Design: In vivo - Cross sectional study. Materials and Methods: A total number of 88 subjects were selected and classified into two groups: 44 subjects with canine guided and 44 subjects with group function occlusal schemes. Condylar and incisal guidance tracings of both the groups were recorded using SAM AXIOQUICK RECORDER (School Articulator Munich) and evaluated. Statistical Analysis Used: Kolmogorov–Smirnov test and Shapiro–Wilk test were employed to test the normality of data. Independent sample t-test and Mann–Whitney U-test was performed for quantitative variables. Results: The condylar and incisal guidance among canine-guided individuals was 31.38 ± 12.01 and 55.83 ± 14.04, respectively, while in group function individuals, it was 29.44 ± 12.65 and 43.74 ± 20.27. Conclusions: Within the limitations of the present study, condylar guidance was similar in subjects with both schemes of occlusion, whereas steeper incisal guidance was noticed in canine-guided individuals as compared to group function.
