to assess FRC FPDs longevity through systematically reviewing contemporary clinical evidence. Population investigated comprised patients requiring replacement of a single missing anterior/posterior tooth. Intervention was FRC FPDs. No control/comparison selected. Outcome was longevity of FRC FPDs. The focus question was: 'What is the longevity of FRC FPDs used to replace one anterior or posterior tooth in patients?'
Randomised, non-randomised, controlled, prospective and retrospective clinical studies were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were applied. The Overall Strength of Clinical Recommendation (OSCR) was assessed using the Strength of Recommendation Taxonomy system. Survival of FPDs was assessed using the Kaplan-Meier method. Analysis of FPD-survival according to location and occurrence of different failures was performed using Logrank and Chi-square testing.
PubMed, MEDLINE, and Web of Science databases were searched between January 2007 and December 2015.
Nine studies were included, involving placement of 592 FRC FPDs in 463 patients. Follow-up periods ranged between 2 months and 8 years. Kaplan-Meier overall survival probability was 94.5% (95%C.I: 92.5%-96.5%) at 4.8 years. There was no significant difference in survival probability of anterior versus posterior FRC FPDs (P=0.278). Veneering material fracture/delamination occurred significantly more than other types of failures (Ps<0.05). A meta-analysis could not be performed. OSCR was moderate.
FRC FPDs demonstrated high overall survival with predictable performance outcomes. However, long-term performance remains unclear.
FRC FPDs are viable medium-term management alternatives for replacing single anterior or posterior teeth in patients.
通过系统回顾当代临床证据评估 FRC FPD 的耐用性。研究人群包括需要更换单个缺失的前牙/后牙的患者。干预措施为 FRC FPD。未选择对照/比较。结局为 FRC FPD 的耐用性。关注的问题是：“用于替换单个前牙或后牙的 FRC FPD 的耐用性如何？”
纳入了随机、非随机、对照、前瞻性和回顾性临床研究。应用了系统评价和荟萃分析的首选报告项目。使用推荐强度分类系统评估总体临床推荐强度（OSCR）。使用 Kaplan-Meier 方法评估 FPD 的存活率。使用 Logrank 和 Chi-square 检验分析根据位置和不同失败类型发生的 FPD 存活率。
在 2007 年 1 月至 2015 年 12 月期间，检索了 PubMed、MEDLINE 和 Web of Science 数据库。
纳入了 9 项研究，共涉及 463 名患者的 592 个 FRC FPD。随访期为 2 个月至 8 年。4.8 年时，Kaplan-Meier 总体生存率为 94.5%（95%CI：92.5%-96.5%）。前牙和后牙 FRC FPD 的生存率无显著差异（P=0.278）。贴面材料断裂/分层的发生率明显高于其他类型的失败（P<0.05）。无法进行荟萃分析。OSCR 为中度。
FRC FPD 总体具有较高的生存率和可预测的结果。然而，长期性能仍不清楚。
FRC FPD 是一种可行的中短期治疗选择，可用于替换单个前牙或后牙。
