The aim of this study was to compare the efficacy of two denture adhesives in edentulous patients wearing complete maxillary and mandibular dentures.
Twenty-four edentulous patients were treated with complete dentures following a standardized protocol. Resistance to dislodgement of both dentures was measured in simulated functional movements by means of a gnathometer and a dynamometer. These outcome measurements were assessed first without the adhesive and then after two successive 2-week periods of using a randomly assigned denture adhesive in a crossover experimental design. The adhesives used were a standard one (Kukident Classic) and a new adhesive with a similar formulation but different physical characteristics (Kukident Pro).
Twenty-four patients (mean age: 58 years) participated in this study. Gnathometer results demonstrated significant differences between the nonadhesive group and both the experimental adhesive (P = .008) and the control adhesive groups (P = .021). Differences between both adhesive groups were not significant (P = .161). Dynamometer results showed highly significant differences between the maxillary and mandibular dentures in both the nonadhesive group and the two adhesive groups (P =or< .0001). Similarly, highly significant differences were found when any of the adhesive groups were compared with the nonadhesive group (P = .0001). The patient subjective evaluation was very favorable for both adhesives.
This study confirms the predicted and expected improvement in the stability and retention of well-fitting complete dentures with the adjunctive use of adhesives. The observed and recorded improvements with the new adhesive as compared to the traditional one were not statistically significant.
本研究旨在比较两种义齿黏附剂对佩戴全口上下颌义齿的无牙颌患者的疗效。
24名无牙颌患者按照标准化方案佩戴全口义齿。通过测颌仪和测力计在模拟功能运动中测量两种义齿的抗脱位性。这些结果测量首先在不使用黏附剂的情况下进行，然后在交叉实验设计中，在连续两个为期2周的时间段内使用随机分配的义齿黏附剂后进行评估。使用的黏附剂一种是标准型（Kukident Classic），另一种是配方相似但物理特性不同的新型黏附剂（Kukident Pro）。
24名患者（平均年龄：58岁）参与了本研究。测颌仪结果显示，未使用黏附剂组与实验黏附剂组（P = .008）和对照黏附剂组（P = .021）之间存在显著差异。两种黏附剂组之间的差异不显著（P = .161）。测力计结果显示，未使用黏附剂组以及两个黏附剂组的上颌和下颌义齿之间存在高度显著差异（P =或< .0001）。同样，当将任何一个黏附剂组与未使用黏附剂组进行比较时，发现存在高度显著差异（P = .0001）。患者对两种黏附剂的主观评价都非常好。
本研究证实了辅助使用黏附剂能使合适的全口义齿的稳定性和固位力得到预期和期望的改善。与传统黏附剂相比，新型黏附剂观察到和记录到的改善在统计学上并不显著。
