AIM
Temporomandibular disorders (TMD) refer to functional disorders of the masticatory system, temporomandibular joint (TMJ) and masticatory muscles. The main objective of this study was to determine whether and to what extent temporomandibular disorders (TMD) affect the maximum bite force (MBF).
METHODS
The present study included subjects with and without temporomandibular disorder. The presence of TMD was assessed by means of the Helkimo clinical dysfunction index analysis. We measured the maximum bite pressure (MBP) and occlusal contact area (OCA) by means of a Fuji Prescale Pressure measurement film. Based on the MBP and OCA values obtained, MBF values were determined.
RESULTS
The MBF values were significantly lower in patients with TMD compared to subjects without TMD (P Conclusion: TMDs have a significant impact on MBF and masticatory muscle action potential. More research is needed to determine the impact of reduced maximum bite force on the functional efficiency of the masticatory system.
目的
颞下颌关节紊乱病（TMD）是指咀嚼系统、颞下颌关节（TMJ）和咀嚼肌的功能紊乱。本研究的主要目的是确定颞下颌关节紊乱病（TMD）是否以及在多大程度上影响最大咬合力（MBF）。
方法
本研究纳入了患有和未患有颞下颌关节紊乱病的受试者。通过赫尔基莫临床功能障碍指数分析评估TMD的存在情况。我们使用富士预刻度压力测量膜测量最大咬压力（MBP）和咬合接触面积（OCA）。根据获得的MBP和OCA值，确定MBF值。
结果
与无TMD的受试者相比，TMD患者的MBF值显著更低（P结论：颞下颌关节紊乱病对最大咬合力和咀嚼肌动作电位有显著影响。需要更多研究来确定最大咬合力降低对咀嚼系统功能效率的影响。
