To compare the efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts.
Sixty-two single rooted maxillary and mandibular central incisor teeth in forty-four patients (15 males and 29 females; age range 15-32 years) were restored either with an ultrahigh molecular weight polyethylene (UHMWP) fiber post (Bondable Reinforcement Ribbon, DENSE, Ribbond, Seattle, WA, United States) or a zircon-rich glass fiber post (Snowpost, Lot H 040; Carbotech, Ganges, France). Then, direct resin composite restoration (Clearfil AP-X, Kuraray) was performed for both post systems in tooth color suitable. Patients were recalled for routine inspections at 6 mo, 1, 2 and 3 years.
The restorations were assessed during each recall evaluation according to predetermined clinical and radiographic criteria (periapical lesion; marginal leakage and integrity; color stability; surface stain and loss of retention of the post or the composite build-up material). The follow-up data showed no significant difference in these criteria between polyethylene fibre posts and zirconia-rich glass fibre posts.
The efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts were similar, suggesting that both types of fiber post can be used successfully to help retain resin composite restorations.
比较用聚乙烯纤维桩或富氧化锆玻璃纤维桩固位的树脂复合材料修复体的疗效。
对44例患者（15例男性和29例女性；年龄范围15 - 32岁）的62颗单根上颌和下颌中切牙，分别用超高分子量聚乙烯（UHMWP）纤维桩（Bondable Reinforcement Ribbon，DENSE，Ribbond，美国华盛顿州西雅图）或富锆玻璃纤维桩（Snowpost，批号H 040；Carbotech，法国甘热）进行修复。然后，对两种桩系统均采用与牙齿颜色匹配的直接树脂复合材料修复（Clearfil AP-X，可乐丽）。在6个月、1年、2年和3年对患者进行定期复查。
在每次复查评估时，根据预定的临床和影像学标准（根尖周病变；边缘渗漏及完整性；颜色稳定性；表面染色以及桩或复合树脂堆积材料的固位丧失）对修复体进行评估。随访数据显示，聚乙烯纤维桩和富氧化锆玻璃纤维桩在这些标准方面无显著差异。
用聚乙烯纤维桩或富氧化锆玻璃纤维桩固位的树脂复合材料修复体疗效相似，表明这两种类型的纤维桩均可成功用于辅助固位树脂复合材料修复体。
