背景：纤维桩具有与天然牙本质接近的弹性模量，在受外力时能够与根管壁保持广泛面接触，与牙本质形成一同质的整体，使应力沿根管壁均匀传导，减少根折的发生。目的：观察纤维桩3种使用方法在前牙漏斗状残根修复中的临床效果。方法：选择48例上前牙根管呈漏斗状患者，随机分为3组，分别采用单根纤维桩、复合树脂重塑根管后应用纤维桩及纤维桩主桩加辅桩进行桩核冠修复，随访2年，观察桩核松动、折断和牙根折断情况。结果与结论：单根纤维桩组发生桩核松动4例、桩核折断4例，修复成功率为64%；复合树脂重塑根管后应用纤维桩组发生桩核松动2例、桩核折断1例，修复成功率为90%；纤维桩主桩加辅桩组发生桩核松动2例，修复成功率为93%。单根纤维桩组修复成功率低于复合树脂重塑根管后应用纤维桩组与纤维桩主桩加辅桩组(P <0.05)，复合树脂重塑根管后应用纤维桩组与纤维桩主桩加辅桩组修复成功率差异无显著性意义。表明使用单根纤维桩直接修复漏斗状残根临床效果不佳，复合树脂重塑根管和纤维桩主桩加辅桩修复前牙漏斗状根管临床效果较好，且纤维桩主桩加辅桩的修复方法临床操作更简单。
揹景：纖維樁具有與天然牙本質接近的彈性模量，在受外力時能夠與根管壁保持廣汎麵接觸，與牙本質形成一同質的整體，使應力沿根管壁均勻傳導，減少根摺的髮生。目的：觀察纖維樁3種使用方法在前牙漏鬥狀殘根脩複中的臨床效果。方法：選擇48例上前牙根管呈漏鬥狀患者，隨機分為3組，分彆採用單根纖維樁、複閤樹脂重塑根管後應用纖維樁及纖維樁主樁加輔樁進行樁覈冠脩複，隨訪2年，觀察樁覈鬆動、摺斷和牙根摺斷情況。結果與結論：單根纖維樁組髮生樁覈鬆動4例、樁覈摺斷4例，脩複成功率為64%；複閤樹脂重塑根管後應用纖維樁組髮生樁覈鬆動2例、樁覈摺斷1例，脩複成功率為90%；纖維樁主樁加輔樁組髮生樁覈鬆動2例，脩複成功率為93%。單根纖維樁組脩複成功率低于複閤樹脂重塑根管後應用纖維樁組與纖維樁主樁加輔樁組(P <0.05)，複閤樹脂重塑根管後應用纖維樁組與纖維樁主樁加輔樁組脩複成功率差異無顯著性意義。錶明使用單根纖維樁直接脩複漏鬥狀殘根臨床效果不佳，複閤樹脂重塑根管和纖維樁主樁加輔樁脩複前牙漏鬥狀根管臨床效果較好，且纖維樁主樁加輔樁的脩複方法臨床操作更簡單。

BACKGROUND:The elastic modulus of the fiber post is close to that of the dentine, so they can form a homogeneous whole and share the masticatory force, which can ease the stress concentration of dentine and prevent from tooth fracture. OBJECTIVE:To observe clinical effects of anterior teeth with flared root canals restored by fiber posts using three application methods. METHODS:Anterior teeth with flared root canals from 48 patients were involved. They were divided into three groups, then restored with three post-core crowns respectively: a single fiber post, rehabilitation with composite resin, and fiber post combined with accessory post. Al patients were folowed up for 2 years to observe post and core loosening, fracture and root fracture. RESULTS AND CONCLUSION:The group of a single fiber post was failed in eight teeth including four cases of post and core loosening and four cases of post and core fracture, with a successful rate of 64%. The group of rehabilitation with composite resin was failed in three teeth including two cases of post and core loosening and one case of post and core fracture, with a successful rate of 90%. The group of fiber post combined with accessory post was failed in two teeth of post and core loosening, with a successful rate of 93%. The successful rate of the group of a single fiber post was lower than that of the groups of rehabilitation with composite resin and fiber post combined with accessory post (P < 0.05) . The difference between the groups of rehabilitation with composite resin and fiber post combined with accessory post was not statisticaly significant (P > 0.05). The clinical effects of rehabilitation with composite resin and fiber post combined with accessory post are better than that of a single fiber post. But the method of combination fiber post with accessory post is recommended because of easy operation.
