摘要
目的 探讨前牙残根残冠使用玻璃纤维桩修复的临床效果。方法 选择2010年1月—2012年5月蚌埠医学院第二附属医院口腔科收治的因前牙大面积缺损需行桩核冠修复的患者76例共108颗患牙作为研究对象,所有患牙经完善的根管治疗后随机分为观察组60颗患牙和对照组48颗患牙,分别采用玻璃纤维桩和铸造金属桩修复,辅以全瓷冠恢复牙体形态,所有患者在修复完成后每隔6个月复查1次,观察记录2组患牙修复后能否行使咀嚼功能、牙龈有无着色、有无牙周袋形成、桩核是否松动脱落或折断及有无根尖周炎等情况,评价其临床效果。结果 108颗患牙在修复后1～2年的随访期间,观察组60颗修复体均未发现牙龈着色、牙周袋、根折及慢性根尖周炎等并发症,1颗修复体发生桩核折断,1颗修复体松动,1颗修复体脱落,共失败3颗,成功57颗,成功率为95%,对照组48颗修复体,1颗修复体发生松动,1颗修复体脱落,2颗牙根折裂,4颗修复体牙龈出现不同程度的灰色或青色,共失败8颗,成功40颗,成功率为83%,2组成功率比较差异有统计学意义（P〈0.05）。结论 玻璃纤维桩生物相容性好,具有良好的临床美学效果,修复前牙残根残冠的临床疗效明显优于铸造金属桩,是一种良好的桩核修复材料,能较好地满足临床需要。
Objective To study the clinical curative effect of glass fiber post applied in the restoration of residual roots and crowns of anterior teeth. Methods 108 anterior teeth of 76 patients in the Department of Stomatology in the Second Affiliated Hospital of Bengbu Medical College were selected. All the teeth had large area defects. And cast post and core on the restoration of the defects were needed for these teeth. All the teeth were randomly divided into the observation group 60 teeth and the control group 48 teeth after perfect root canal treatment. Glass fiber post and casting metal post restoration were respectively given to the two groups. And the all-ceramic dental crown restoration was given to them too. All of the patients were followed up for every 6 months after the restoration. Masticatory function,gingival color,periodontal pocket, secondary caries,the fall off of the pile nuclea,the break of pile nuclear and periapical periodontitis were compared. The clinical effect was evaluated. Results All the cases were followed up at least twelve to twenty-four months. In observation group,1 pile nuclear was found broken,1 restoration was loose and 1 restoration fell off. So the restoration of 57 teeth succeeded and three failed. And the success rate was 95%. There was 1 loose restoration,1 lost restoration,2 dental root fracture and 4 gingival discoloration in the control group. So the restoration of 40 teeth succeeded and eight failed. The success rate was 83%. There were statistically significant differences（ P〈0. 05） in the success rate of the two groups. Conclusion The glass fiber post restoration applied in the residual roots and crowns in anterior teeth had more better effect than that of metal post and could better meet the clinical needs.
