Comparison of occlusal bite force distribution in subjects with different occlusal characteristics

Objective To analyze bite force distribution in subjects with different occlusal characteristics. Methods This prospective study included 132 candidates (50 males, 82 females) seeking orthodontic treatment, who were divided into four groups based on Angle's classification of malocclusion. T-Scan (R) III Version 7.0 was used to record their relative distribution of bite forces, which were compared using gender, Angle's occlusal classification, overjet, overbite, space analysis, sagittal, and transverse skeletal relations variables. Results ANOVA revealed significant differences in posterior/anterior bite force ratios between sagittal dental and skeletal relationships, overjet, and overbite groups (p< 0.05). No significant difference was found between different space analysis and transverse relationship groups (p> 0.05) or between genders (p> 0.05). Conclusion Subjects with Class III, decreased overjet and decreased overbite displayed higher bite force in posterior teeth compared to other groups. This feature must be considered when evaluating patients with dental and periodontal pathologies that might be affected by excessive tooth stress, especially in subjects with oral parafunctions and bruxism.

Automated summary

This study aimed to analyze the distribution of bite forces in individuals with different occlusal characteristics. The study found that subjects with Class III malocclusion, decreased overjet, and decreased overbite had higher bite forces in the posterior teeth compared to other groups.
