目的：探讨使用新型数字化工作流程制作的一件式聚醚醚酮（PEEK）可摘局部义齿（RPD）的临床应用，并评估其体内重量和配合度以及患者满意度。
方法：选择15例后部分缺牙患者，每个病人接受两种类型的RPD,包括新颖的数字工作流程（测试组）和常规工作流程（对照组）。对于测试组，一件式RPD是通过扫描石材铸件并通过铣削PEEK圆盘通过三维（3D）方法设计的。称重每个RPD。使用聚乙烯基硅氧烷(PVS)复制品复制每组中的口腔组织和RPD之间的间隙,并通过3D分析测量。使用视觉模拟量表（VAS）评估患者的满意度。配对t检验用于比较体重的差异，每个RPD的间隙，两组之间的VAS值。采用单因素方差分析比较各组不同成分之间差距的差异。
结果：试验组的RPD小于对照组（p<0.01）。两组义齿基托间隙和坐垫间隙差异无统计学意义(p>0.05),但试验组主要接头的间隙明显小于对照组(p<0.05)。两组的舒适度和咀嚼效率的VAS评分无明显差异（p>0.05），但试验组的扣的美观性评分明显高于对照组（p<0.05）。
结论：使用新型数字工作流程制造的一体式PEEKRPDs的重量小于常规RPDs，并且表现出临床上可接受的内部配合。尽管PEEK扣环的美学外观优于对照，仍有改进的空间。
OBJECTIVE: To explore the clinical application of one-piece polyetheretherketone (PEEK) removable partial dentures (RPDs) fabricated using a novel digital workflow and to evaluate their weights and fits in vivo and patient satisfaction.
METHODS: Fifteen cases with posterior partially edentulous situations were selected, and each patient received two types of RPDs, including a novel digital workflow (test group) and a conventional workflow (control group). For the test group, one-piece RPDs were designed through three-dimensional (3D) methods by scanning stone casts and fabricated by milling PEEK discs. Each RPD was weighed. The gaps between the oral tissue and RPDs in each group were duplicated using a polyvinylsiloxane (PVS) replica and measured by 3D analysis. A visual analog scale (VAS) was used to evaluate the patient\'s satisfaction. Paired t-tests were used to compare the differences in the weight, the gaps of each RPD, and VAS values between the two groups. One-way analysis of variance tests was used to compare the differences in the gap among different components in each group.
RESULTS: The RPD in the test group weighed less than that in the control group (p < 0.01). No statistically significant differences in the gaps of denture bases and rests (p > 0.05) were found between the two groups, but the gaps of major connectors in the test group were significantly smaller than in the control group (p < 0.05). The VAS scores for comfortableness and masticatory efficiency were not significantly different between the two groups (p > 0.05) but the scores for the aesthetic appearance of the clasps in the test group were significantly higher than that in the control group (p < 0.05).
CONCLUSIONS: One-piece PEEK RPDs manufactured using a novel digital workflow weighed less than conventional RPDs and exhibited a clinically acceptable internal fit. Although the aesthetic appearance of the PEEK clasps was superior to the control, there is still room for improvement.
