目的：采用随机、交叉设计的临床试验，研究单个种植体固定的下颌覆盖义齿的患者满意度和咀嚼效率。方法：将单个种植体放置在下颌中线，随机分配螺柱(Locator)或磁性(Magfit)附着体。在佩戴附着体前和3个月后评估患者的满意度，包括患者的舒适度、言语、咀嚼能力和固位力，以及通过咀嚼花生测量的咀嚼效率。在放置替代附着体3个月后再次评估患者满意度和咀嚼效率。结果：患者的总体满意度、舒适度、言语、咀嚼能力和固位力在放置后均有显著改善(p<；0.05)。Locator组和Magfit组的咀嚼效率也都有所提高(p<；0.05)。两种附着体在患者总体满意度、舒适性、言语和保持能力方面没有统计学上的显著差异(p>；0.05)。Locator附着体的咀嚼能力明显好于Magfit附着体(p<；0.05)，但两种附着体的咀嚼效率差异无统计学意义(p>；0.05)。结论：使用Locator附着体和Magfit磁性附着体的下颌种植覆盖义齿的临床效果显著改善。两种附着体的咀嚼效率无明显差异。(C)2012 Ltd.保留所有权利。
Objectives: To study patient satisfaction and masticatory efficiency of single implant-retained mandibular overdentures using the stud and magnetic attachments in a randomized clinical trial with a crossover design.Methods: Patients received a single implant placed in the midline of the mandible and either a stud (Locator) or a magnetic (Magfit) attachment, assigned at random. Patient satisfaction, including patient comfort, speech, chewing ability and retention, and masticatory efficiency measured by chewing peanuts, were assessed before and 3 months after attachment insertion. Patient satisfaction and masticatory efficiency were evaluated again 3 months after insertion of the alternate attachment bodies. The outcomes were compared before and after insertion of the attachments and between the two types of attachments using Wilcoxon signed rank tests.Results: Patient overall satisfaction, comfort, speech, chewing ability, and retention improved significantly after insertion of both types of attachment bodies (p < 0.05). Masticatory efficiencies also increased in both the Locator and the Magfit groups (p < 0.05). There were no statistically significant differences in patient overall satisfaction, comfort, speech, and retention between the two types of attachments (p > 0.05). The Locator attachments performed better in perceived chewing ability than the Magfit (p < 0.05), but there was no statistically significant difference in masticatory efficiency between the two attachment types (p > 0.05).Conclusions: Clinical outcomes were significantly improved in single implant-retained mandibular overdentures using either the Locator or the Magfit magnetic attachments. There was no difference in masticatory efficiency between the two attachment types. (c) 2012 Ltd. All rights reserved.
