The signs and symptoms of temporomandibular dysfunction (TMD) may contribute to reduce bite force and muscular activity. The aims of this study were to compare bite force in complete denture wearers with TMD (TMD group) and without TMD (healthy group).The TMD group consisted of 9 individuals, who had worn a maxillary and a mandibular complete removable denture for more than 10 years. The healthy group consisted of 9 participants who wore dentures and had satisfactory interocclusal and maxillomandibular relationship. Helkimo Index was used to analyze the dysfunction level. Maximum bite force was measured using a digital dynamometer with capacity of 100 kgf and adapted to oral conditions.The TMD group presented smaller mean bite force values than the healthy group, though without statistical significance (p>0.05). This outcome suggests that the TMD signs and symptoms and the structural conditions of the dentures did not affect the maximal bite force of complete denture wearers.
颞下颌关节紊乱病(TMD)的体征和症状可能会导致咬合力和肌肉活动降低。本研究的目的是比较患有TMD的全口义齿佩戴者(TMD组)和未患TMD的全口义齿佩戴者(健康组)的咬合力。TMD组由9名个体组成,他们佩戴上颌和下颌全口可摘义齿超过10年。健康组由9名佩戴义齿且具有满意的咬合间关系和颌间关系的参与者组成。使用赫尔基莫指数分析功能紊乱程度。使用容量为100千克力并适应口腔条件的数字测力计测量最大咬合力。TMD组的平均咬合力值低于健康组,尽管无统计学意义(p>0.05)。这一结果表明,TMD的体征和症状以及义齿的结构状况并未影响全口义齿佩戴者的最大咬合力。
