Abstract
OBJECTIVE
This study was performed to determine the maximum voluntary molar bite force (MVMBF) in relation to age, sex, lip competency, midline shifting, dental and skeletal malocclusion, overjet, overbite, and crowding.
METHODS
One hundred Saudi patients with orthodontic malocclusion aged 14 to 25 years (51 male and 49 female patients) were investigated in this cross-sectional study. The baseline MVMBF on the right and left side was evaluated in all patients before commencing any orthodontic treatment. The MVMBF was registered with a portable occlusal force gauge in the first molar region during maximal clenching.
RESULTS
The MVMBF significantly varied with respect to all nine confounding variables. The MVMBF significantly increased with an age of >18 years, male sex, right-side lip competency, no midline shift, dental and skeletal Class I malocclusion, normal overjet, normal overbite, and mild crowding.
CONCLUSION
All nine variables examined in the present study significantly influenced the MVMBF.
摘要
目的
本研究旨在确定最大自主磨牙咬合力（MVMBF）与年龄、性别、唇功能、中线移位、牙颌和骨骼错颌畸形、覆颌、覆盖和拥挤的关系。
方法
本横断面研究调查了 100 名沙特正畸错颌患者，年龄在 14 至 25 岁之间（51 名男性和 49 名女性患者）。在开始任何正畸治疗之前，所有患者的右侧和左侧基线 MVMBF 均用便携式咬合力计进行评估。在最大紧咬时，MVMBF 在第一磨牙区用便携式咬合力计记录。
结果
MVMBF 与所有九个混杂变量显著相关。MVMBF 随年龄>18 岁、男性、右侧唇功能正常、无中线移位、牙颌和骨骼 I 类错颌畸形、正常覆颌、正常覆盖和轻度拥挤而显著增加。
结论
本研究中检查的所有九个变量均显著影响 MVMBF。
