摘要：

背景：由于铸造金属桩核弹性模量大，修复磨牙残冠残根时易造成根尖部根折，难以取出、生物相容性差等缺点。
目的：评价多个玻璃纤维桩修复磨牙残冠的临床效果。
方法：选择26例31颗磨牙残冠，经完善根管治疗后，选择两至三个根管制作玻璃纤维桩树脂核，然后进行氧化锆全瓷冠修复，随访观察治疗效果。
结果与结论：随访12~24个月，3颗全瓷冠出现颜色偏差，因后牙对美观影响不大，患者未提出异议；1颗冠崩瓷而重做外冠，1颗冠因邻接关系不良导致食物嵌塞而重做外冠，1颗冠因牙合龈距离低，聚合度过大冠脱落，经增加辅助固位型后重做外冠，重做外冠观察半年以上未见异常。其余病例修复体外形良好，边缘密合，X射线检查桩与根管密贴，无桩或根折，根尖根周牙槽骨无吸收影像。表明多纤维桩树脂核技术修复磨牙残冠能够获得良好的近期临床效果。

Abstract:

BACKGROUND: Cast metal posts with big elastic modulus and poor biocompatibility can result in apical root fractures that are difficult to remove during residual molar crown repairment. 
OBJECTIVE: To evaluate the therapeutic effects of multi-fiber posts on the restoration of the molar residual root and crown.
METHODS: A total of 26 patients with 31 molars were included. After satisfactory root canal therapy, the teeth were repaired using two or three glass fiber posts and zirconia-ceramic crowns.
RESULTS AND CONCLUSION: During 12-24 months of clinical follow-up, one had food impaction for bad adjacency, one had abscission of all-ceramic crown, one had porcelain collapse caused by hard food biting. No loosening, fracture and gap existed among fiber post, composite resin core, dentine and crown. No dislodgment or fracture of posts or roots was observed in restorations. Multi-fiber post and cores and all-ceramic crown are reliable and ideal materials in the restorations of molar residual root and crown.
