The purpose of this study was to determine the effect of oral moisturizing agents, denture adhesives, and surface treatments on the retention of an acrylic resin test base dislodged from the maxillary alveolar ridges of xerostomic radiotherapy patients. Acrylic resin test bases prepared for 10 edentulous xerostomia patients were subjected to 8 surface treatment methods: method 1 = untreated dry surface; method 2 = use of Biotène oral moisturizer; method 3 = use of Protefix denture adhesive; method 4 = combination of Biotène and Protefix; method 5 = sandblasting of test bases; method 6 = use of Biotène on sandblasted surface; method 7 = use of Protefix on sandblasted surface; method 8 = combination of Protefix and Biotène on sandblasted surface. After each treatment, a tensile testing apparatus was used to dislodge the inserted test bases, and force values (N) were recorded. A significant difference in retentive force was observed between the 4 Protefix groups and those that did not use denture adhesive (P < .001). There were no differences among the 4 combinations of denture adhesive treatments (P > .05). Sandblasting the denture surfaces did not increase retentive forces alone or in combination with any other treatments. Biotène oral moisturizing agent was used in 4 treatment methods, but only had a significant effect on increasing retentive force when used with a nonsandblasted surface (P < .05). Biotène had no effect on retentive force compared to a nonsandblasted surface without moisturizer or when it was used in combination with any other methods. Protefix denture adhesive offered the greatest improvement in retentive force. Sandblasting the intaglio surface did not improve retentive force. Biotène was reported to improve patient comfort but had minimal effect on retentive force; however, Biotène can be assumed to be a more advantageous method of increasing retention compared to sandblasting (P < .05).
本研究的目的是确定口腔保湿剂、义齿黏附剂和表面处理对从口干燥症放疗患者上颌牙槽嵴脱位的丙烯酸树脂试验基托固位力的影响。为10名无牙口干燥症患者制备的丙烯酸树脂试验基托接受了8种表面处理方法：方法1 = 未处理的干燥表面；方法2 = 使用保丽净口腔保湿剂；方法3 = 使用普特固定义齿黏附剂；方法4 = 保丽净和普特固定联合使用；方法5 = 试验基托喷砂处理；方法6 = 在喷砂表面使用保丽净；方法7 = 在喷砂表面使用普特固定；方法8 = 在喷砂表面联合使用普特固定和保丽净。每次处理后，使用拉伸试验装置使插入的试验基托脱位，并记录力值（N）。观察到4个使用普特固定的组与未使用义齿黏附剂的组之间固位力有显著差异（P < .001）。义齿黏附剂处理的4种组合之间没有差异（P > .05）。单独对义齿表面进行喷砂处理或与任何其他处理联合使用均未增加固位力。保丽净口腔保湿剂在4种处理方法中使用，但仅在与未喷砂表面联合使用时对增加固位力有显著影响（P < .05）。与未使用保湿剂的未喷砂表面相比，或与任何其他方法联合使用时，保丽净对固位力没有影响。普特固定义齿黏附剂在固位力方面提供了最大程度的改善。对组织面进行喷砂处理并未提高固位力。据报道，保丽净可提高患者舒适度，但对固位力影响最小；然而，与喷砂处理相比，保丽净可被认为是增加固位力的更有利方法（P < .05）。
