目的探讨玻璃纤维根管桩内固定治疗前牙根折的临床效果。方法选择2008年2月至2010年2月于创伤后24h至10d来淄博市中心医院口腔科就诊的前牙根折或冠根联合折患者28例(36颗患牙)。患牙经初步外固定及一次法根管治疗7d后,行高强度玻璃纤维根管桩根管内固定,使牙根两断端重新连接,冠完好者自体冠再黏结,冠折裂者行烤瓷冠修复。结果术后随访2年,28例患者36颗患牙中,成功26例34颗牙,成功率94.4%。结论采用高强度玻璃纤维根管桩内固定治疗创伤性前牙根折是一种快速、有效的新技术,值得应用推广。
Objective To investigate the clinical effect of fiberglass root canal internal fixation for anterior root fracture. Methods From February 2008 to February 2010, 28 cases (36 teeth) of anterior root fracture or canopy root fracture were treated in Department of Stomatology, Zibo Central Hospital from 24 to 10 days after trauma. After initial external fixation of tooth and primary root canal treatment for 7 days, the root canal of high-strength glass fiber reinforced plastic was fixed with root canal, the two ends of root were reconnected, Porcelain crown repair. Results The patients were followed up for 2 years. Twenty-six teeth of 28 patients succeeded in 26 cases and 34 teeth, the success rate was 94.4%. Conclusion The treatment of traumatic anterior root fracture with high-strength glass fiber reinforced plastic post is a rapid and effective new technique, which deserves to be popularized.
