To analyze bite force distribution in subjects with different occlusal characteristics.
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® 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.
ANOVA revealed significant differences in posterior/anterior bite force ratios between sagittal dental and skeletal relationships, overjet, and overbite groups ( < 0.05). No significant difference was found between different space analysis and transverse relationship groups ( > 0.05) or between genders ( > 0.05).
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.
分析不同咬合特征患者的咬合力分布。
本前瞻性研究纳入了 132 名（男 50 名，女 82 名）寻求正畸治疗的患者，根据安氏错牙合分类将他们分为四组。使用 T-Scan® III Version 7.0 记录他们的咬合力相对分布，并通过性别、安氏错牙合分类、覆牙合、覆盖、间隙分析、矢状和横向骨骼关系变量进行比较。
方差分析显示，后牙/前牙咬合力比值在矢状牙和骨骼关系、覆牙合、覆盖组之间存在显著差异（<0.05）。不同间隙分析和横向关系组之间（>0.05）或性别之间（>0.05）无显著差异。
安氏 III 类、覆牙合减少和覆盖减少的患者后牙的咬合力比其他组更高。在评估可能受到过度牙齿应力影响的牙体和牙周病理的患者时，尤其是在存在口腔功能紊乱和磨牙症的患者中，必须考虑到这一特征。
