目的：本研究的目的是研究用于远端可摘局部义齿辅助支撑的种植体应变。材料和方法：在平行和倾斜两个位置使用带应变片的种植体进行测试。研究了三种加载方案：加载器（LA）、棉辊人工牙（CR）和人工牙（UT），并通过Kruskal-Wallis检验比较应变（P = 0.05）。结果：CR组菌株显著大于UT组菌株（P < 0.05）。然而，在斜上观察到相反的情况。结论：UT的平行应变最小，CR的倾斜应变最大。
Purpose: The aim of this study was to investigate strain on implants used for adjunctive support of distal extension removable partial dentures. Materials and Methods: An implant with strain gauges was used for testing purposes in two positions, parallel and inclined. Three loading scenarios loading apparatus (LA), artificial teeth via cotton roll (CR), and artificial teeth (UT) were studied and strains compared via the Kruskal-Wallis test (P = .05). Results: Strain under CR was significantly larger than UT in parallel (P < .05). However, the opposite was observed in inclined. Conclusions: Strain in parallel was smallest for UT, whereas in inclined it was largest for CR.
