摘要： 摘要：目的 评价石英纤维增强树脂桩核修复残根、残冠的临床应用效果。方法 选择2004年1月至2006年1月于济南市口腔医院修复科就诊的牙体缺损患者98例，共156颗患牙，均为经完善根管治疗的残根、残冠，随机分为石英纤维增强树脂桩核组（49例72颗患牙）和铸造金属桩核组（49例84颗患牙），金瓷冠修复后随诊3年。结果 石英纤维增强树脂桩核组无一例根折裂发生，仅有1颗修复体发生桩折断;而铸造金属桩核组发生根折4颗、铸造金属桩核脱落3颗，出现牙龈色素沉着8颗。石英纤维增强树脂桩核组3年修复成功率（71／72，98.6%）明显高于铸造金属桩核组（69／84，82.1%），二者差异有统计学意义。结论 石英纤维增强树脂桩核具有良好的美学效果，强度高，抗疲劳、抗腐蚀性及生物相容性好且不易造成根折，是残根、残冠修复的理想选择。

Abstract: Abstract：Objective To evaluate the clinical effects of restoration of residual crown and resalidual root with quartzfiber-reinforced composite post and core. Methods A total of 98 patients with 156 endodontically treated teeth who visited the Department of Prosthodontics of Jinan Stomatological Hospital were selected from January 2004 to January 2006. The patients were divided into quartzfiber-reinforced composite post and core group（49 cases with 72 defected teeth）and cast metal post and core group（49 cases with 84 defected teeth）randomly. All the teeth were restored with PFM crown. The therapeutic effects were observed after 3 years. Results During 3 years of clinical observation there was no one root fracture happening in quartzfiber-reinforced composite post and core group，only 1 post and core fractured. In cast metal post and core group 4 teeth were found root fracture，3 cast metal post and core were loose and 8 teeth were with gingival grey line. The successful rate of quartzfiber-reinforced composite post and core group（71／72，98.6%）was significantly higher than cast metal post and core group（69／84，82.1%），with significantly statistical difference in two groups. Conclusion Quartzfiber-reinforced composite post and core has excellent aesthetic performance;it has high-strength，fatigue-resistance，erosion-resistance and good biocompatibility without root fractures. So it is a good choice in the restoration of residual crown and residual root.
