纤维桩联合复合树脂美学修复青少年上前牙冠折的临床观察

目的 探讨纤维桩联合复合树脂美学修复在青少年上前牙冠折的临床修复效果。方法 选取2015年1月至2017年3月在我科就诊的52例63颗牙根已发育完成的青少年上前牙冠折病例，年龄11~16岁，对残冠残根完善根管治疗后进行纤维桩联合复合树脂美学冠修复，临床追踪观察2年。从修复体边缘有无渗漏、牙龈色泽、牙周状况、纤维桩有无松动、折断、脱落进行检查记录，观察临床效果。结果 52例患者均获24个月随访，通过临床检查及影像学检查判定修复结果，在整个复诊期间，98.4%的修复体形态自然、颜色逼真、边缘密合性较好；纤维桩稳固无松动、无折裂；牙龈牙周状况良好，患者无临床不适症状，达到满意的临床效果。1例患者修复后15个月再次受外伤致修复体脱落。结论 纤维桩联合复合树脂美学冠修复青少年上前牙冠折，操作简便，患者就诊次数少，临床效果理想。

Clinical observation of fiber post combined with composite resin aesthetic restoration of dental crown fracture of upperanterior teeth in adolescents

Objective The aim of this study watto investigate the clinical effect of fiber post and core crown in the aesthetic restoration of dental crown fracture of upperanterior teeth in adolescents.
