Abstract

The aim of this study was to evaluate the change in occlusal force at denture dislodgement (OFD) in patients with poorly fitting complete dentures after improvement. In 91 patients, OFD was recorded before treatment, immediately after fitting the renewed denture (direct effect), and 1 week, 1 month, and 6 months later (adaptation). OFD increased significantly (P < .01) after optimizing the dentures and was dependent on patients' gender and age. The greatest changes occurred within the first week. It can be concluded that the increase in OFD is not only induced by the optimized denture, but also-and to an even greater extent--by adaptation.

摘要

本研究的目的是评估义齿贴合不佳的全口义齿患者经改善后义齿脱位时的咬合力（OFD）变化。对91例患者在治疗前、重新佩戴义齿后即刻（直接效应）以及1周、1个月和6个月后（适应性变化）记录OFD。优化义齿后，OFD显著增加（P <.01），且与患者的性别和年龄有关。最大的变化发生在第一周内。可以得出结论，OFD的增加不仅是由优化后的义齿引起的，而且在更大程度上是由适应性变化引起的。
