(1) Background: An alternative material to precious metal alloys are non-precious metal alloys. The material properties of these are different and, therefore, their clinical, biological and mechanical behaviors may also differ. Hence, the purpose of this in vivo investigation was to analyze the clinical and patient-reported outcomes of patients restored with non-precious metal alloy double crown-retained removable partial dentures (NP-D-RPDs). (2) Methods: Partially edentulous patients were restored with non-precious metal alloy partially veneered NP-D-RPDs. Survival rates, success rates, failures and patient-reported outcomes were investigated and statistically evaluated. (3) Results: A total of 61 patients (65.6 ± 10.8 years) were included and clinically and radiographically examined. The mean follow-up time was 25.2 ± 16.5 months. In total, 82 NP-D-RPDs and 268 abutment teeth were examined. The overall survival rate of the NP-D-RPDs was 100% after a mean follow-up time of 2.1 years. The overall success rate was 68.3%. The overall satisfaction with the NP-D-RPDs was 94.3%. (4) Conclusions: Non-precious metal alloy partially veneered NP-D-RPDs seem to be an efficient alternative to precious metal alloy RPDs with excellent patient-reported outcomes.
(1) 背景：非贵金属合金是贵金属合金的一种替代材料。这些材料的性能不同，因此它们的临床、生物学和力学行为也可能不同。因此，本体内研究的目的是分析使用非贵金属合金双冠固位可摘局部义齿（NP-D-RPDs）修复的患者的临床和患者报告的结果。(2) 方法：为部分牙列缺损患者使用非贵金属合金部分贴面NP-D-RPDs进行修复。对生存率、成功率、失败情况和患者报告的结果进行调查并进行统计学评估。(3) 结果：共纳入61例患者（65.6±10.8岁），并进行了临床和影像学检查。平均随访时间为25.2±16.5个月。总共检查了82副NP-D-RPDs和268颗基牙。NP-D-RPDs的平均随访2.1年后总体生存率为100%。总体成功率为68.3%。患者对NP-D-RPDs的总体满意度为94.3%。(4) 结论：非贵金属合金部分贴面NP-D-RPDs似乎是贵金属合金RPDs的一种有效替代方案，患者报告的结果良好。
