摘　　要：目的评价ParaPost Fiber Lux玻璃纤维桩修复下颌前磨牙残根、残冠的临床效果。方法选择98例患者共123颗患牙,行完善的根管治疗后,随机分为两组：A组62颗牙行ParaPost Fi-ber Lux桩核系统修复,B组61颗牙行成品螺纹桩加树脂核系统修复,所有患牙完成桩核后制作金属熔附烤瓷全冠,随访1-2年,通过临床检查和X线检查记录修复效果。采用SPSS11.0软件包对残根、残冠成功率作χ^2检验。结果在随访中,A组有4颗出现牙龈充血、水肿,其余牙无松动,无折裂,冠边缘密合,牙周指数正常;B组有7颗牙发生修复体脱落,3颗牙根折,3颗出现牙龈充血、水肿。A组成功率（93.55%）高于B组（78.69%）,有统计学意义（P〈0.05）。结论 ParaPost Fiber Lux纤维桩系统修复下颌前磨牙残根、残冠,是一种较为理想的桩核修复系统。Objective To evaluate the clinical efficacy of ParaPost Fiber Lux system in prosthodontic treatment for the residual root and crown.Methods 123 teeth of 98 patients were selected to perform root canal therapies.The cases were divided into 2 groups randomly： 62 teeth in group A were restored with glass fiber reinforced posts and cores,and 61 teeth in group B were restored with screwed mental posts.All patients were followed up for 1 to 2 years after treatment.Results were statistically analyzed with SPSS11.0 software for Chi-square test.Results During the following up period,4 out of 62 teeth in group A were observed to have gingival hyperemia while others were functioned well with good marginal fit,while 7 crown loose and 3 root fracture and 3 gingival hyperemia were found in group B.The success rate of group A（93.55%） was higher than group B（78.69%）,there was a significant difference（P〈0.05）.Conclusion The ParaPost Fiber Lux system is promising in prosthodentics,because of its nice biologic property,natural aesthetic,convenience to be handle and wide application.
