Bennett angle at different Angle’s classes of occlusion

Purpose: The Bennett angle is an important parameter during prosthodontic rehabilitation. Existing data about impact of different occlusion types on the values of the Bennett angle are scarce. The purpose of this study was to investigate effect of different occlusion types on the Bennett angle values. Materials and Methods: Study included 98 participants (26.0 ± 5.2 years) divided into four study groups: Angle’s class I, Angle’s class II, subdivision 1, Angle’s class II, subdivision 2 and Angle’s class III. All recordings were obtained using ultrasound jaw tracking device with six degrees of freedom. After paraocclusal tray was fixed on the lower jaw, every subject had to make three protrusive, three left and right laterotrusive movements. From the laterotrusive movements, device’s software automatically calculated Bennett angle values for left and right joints, and data were statistically analyzed. Results: One-way ANOVA did not show differences between different Angle’s classes of occlusion for the Bennett angle values. Average Bennett angle value for all participants was 7.7°. Conclusions: Our results suggest that different Angle’s classes of occlusion do not have impact on the Bennett angle values. Average value of the Bennett angle is 8°, and should be used for average articulator settings.
