Recently, polyetherpolyetherketone (PEEK) has gained popularity as a dental biomaterial. However, there is a lack of consensus on its potential use as an endodontic post-core material. The aim of this review was to systematically critique and synthesize the evidence on PEEK-based post-cores in comparison to other materials. An electronic search was conducted on PubMed, Medline, Embase, ISI Web of Science, Ovid, Cochrane, and ClinicalTrials.Gov using relevant keywords. Seven studies were included in this review. Meta-analysis of fracture resistance was carried out on results reported in three studies. Overall, in most of the studies, PEEK post-cores performed similar to glass-fiber post-cores. The meta-analysis revealed no significant difference between the fracture strengths of PEEK and glass-fiber post-cores. However, in most studies, several sources of bias were identified. Within the limitations of this review, it may be concluded that mechanical and physical properties of PEEK posts are similar to those of glass-fiber post-cores. Nonetheless, long-term clinical studies are required to translate these conclusions into clinical practice.
近年来，聚醚醚酮（PEEK）作为一种牙科生物材料越来越受欢迎。然而，对于其作为根管桩核材料的潜在用途，目前尚无共识。本综述的目的是系统地批判和综合与其他材料相比，基于PEEK的桩核的相关证据。使用相关关键词在PubMed、Medline、Embase、ISI科学网、Ovid、Cochrane和ClinicalTrials.Gov上进行了电子检索。本综述纳入了七项研究。对三项研究所报告的结果进行了抗折性的荟萃分析。总体而言，在大多数研究中，PEEK桩核的性能与玻璃纤维桩核相似。荟萃分析显示，PEEK和玻璃纤维桩核的抗折强度之间没有显著差异。然而，在大多数研究中，发现了几个偏倚来源。在本综述的局限性范围内，可以得出结论，PEEK桩的机械和物理性能与玻璃纤维桩核相似。尽管如此，仍需要长期的临床研究将这些结论应用于临床实践。
