两种方法修复大面积牙体缺损的临床效果对比 　　[摘要] 目的 探讨纤维桩与传统铸造金属桩核修复大面积牙体缺损的临床效果。 方法 选取本院2010年6月～2012年8月收治的116例牙体大面积缺损患者，随机均分为实验组和对照组，实验组患者行纤维桩修复，对照组患者行传统铸造金属桩核修复。比较两组患者治疗成功率和不良缺陷发生率的差异。 结果 实验组患者治疗成功率为87.93%（51/58），显著高于对照组的60.34%（35/58）（P0.05）；实验组不良缺陷发生率为15.52%（9/58），低于对照组的58.62%（34/58），两组比较差异有统计学意义（P0.05）。 结论 纤维桩修复大面积牙体缺损效果显著优于传统铸造金属桩核修复，治疗成功率高，不良缺陷少，值得临床推广使用。 　　[关键词] 纤维桩；传统铸造金属桩核；牙体缺损；临床效果 　　[中图分类号] R783.3 [文献标识码] A [文章编号] 1674-4721（2013）11（b）-0012-02 　　Comparative on clinical efficacy of two methods for the restoration of large area of defective tooth 　　ZHAO Kun-xiang YU Qin XU Cui-rong LI Shu-qin 　　Department of Stomatology，Hospital of Integrative Chinese Western Medicine in Nanchang City，Nanchang 330003，China 　　[Abstract] Objective To investigate the clinical efficacy of fiber post and traditional cast metal post for the restoration of large area of defective tooth. Methods 116 cases of patients with large area of defective tooth selected in our hospital from June 2010 to August 2012 were randomly divided into experimental group and control group.The experimental group were received fiber post restoration.The control group were received traditional cast metal post restoration.The treatment success rate and adverse defects rate of two groups were compared. Results The treatment success rate of experimental group was 87.93% （51/58），which was significantly higher than 60.34% （35/58） of control group （P0.05）.The adverse defects rate of experimental group was 15.52% （9/58），which was significantly lower than 58.62%（34/58） of control group （P0.05）. Conclusion Fiber post restoration is more effective than traditional cast metal post restoration for large area of defective tooth with high treatment success rate and low adverse defects.It′s worth of clinical widely used. 　　[Key words] Fiber post；Traditional cast metal post；Defective tooth；Clinical efficacy 　　大面积牙体缺损是临床常见症状。牙齿缺损常见的原因是龋病，其次为外伤、磨损、楔状缺损、酸蚀和发育畸形[1-2]。发育畸形常见的为釉质发育不全、斑釉牙及过小牙等[3]。轻度釉质发育不全者牙冠呈白垩色或褐色斑，严重者则出现牙冠形态不完整，釉质钙化不
