摘要
目的:探讨对纵折后牙采用Vitapex结合桩核冠修复治疗的可行性。方法:对29例纵折后牙,通过Vitapex控制根分叉区感染,促进骨质愈合,常规根管治疗,结扎患牙后行铸造桩核内固定,全冠固定修复。治疗后随访30～42个月,根据临床、X线检查和患者主诉评价修复效果。采用SPSS10.0软件包对相关数据进行χ2检验。结果:29例纵折患牙成功修复27例,临床成功率达93.1%。失败病例中,1例因重度牙周炎而拔除,1例因再次折裂而拔除。根据患牙折裂后就诊时间不同(<1d,1～7d,8～30d)进行比较,组间存在差异,说明折裂后越早治疗,成功率越高。结论:Vitapex结合桩核冠修复,对保存折裂后牙疗效满意。
PURPOSE： To study the possibility of treatments of vertically fractured teeth with Vitapex and post-core crown. METHODS： 29 vertically fractured teeth were involved in this study, all the traumatized teeth were treated with Vitapex to control the furcation involvement and accelerate the healing of bone tissue, with root canal therapy and postcore crown to fix. The clinical effects were investigated in the following 30 to 42 months. The restorative results were evaluated with clinical examination, radiological examination and chief complaints of the patients.The data were analyzed with SPSS10.0 software package for Chi-square test. RESULTS： The outcomes of restorations in 27 teeth were satisfactory. The success rate was 93.1%. Only two restorations were failed due to severe periodontitis and refracture. The difference between the groups was statistically significant based on different times to treat after fracture （〈lday, lday- 7days,8-30days）. The results demonstrated that the earlier to treat the fractured teeth, the better results we got. CONCLUSION： Vitapex and post-core crown is a promising therapy for vertically fractured teeth.
