摘要/Abstract

摘要： 目的观察用玻璃纤维桩和流动树脂修复前牙、前磨牙重度楔状缺损的临床效果。方法选取72例重度楔状缺损且未伴发龋坏的前牙和前磨牙，经根管治疗后，随机分为A、B、C三组各24颗牙。A组：单纯使用Z350流动树脂修复；B组：Z350流动树脂+玻璃纤维桩修复；C组：Z350流动树脂+玻璃纤维桩+全冠修复。在统一评价标准下进行对比观察。结果经2年随访观察，A组成功率62.5%，B组成功率87.5%，C组成功率91.7%，经卡方检验，A、B两组差异有统计学意义（P<0.05）。B、C组差异无统计学意义（P>0.05）。结论纤维桩能显著提高重度楔状缺损的提高其抗折性能，改善楔缺充填材料的稳定性能；全冠对重度楔状缺损修复的效果并不明显，值得进一步探讨。

Abstract: Objective To observe the clinical effects of glass fiber pile and liquid resin in severe wedge-shaped defect restorations of premolar and anterior teeth. Methods 72 cases with severe wedge-shaped defect of the premolar and anterior teeth were selected. After the treatment of root canal, 24 teeth were randomly divided into three groups: Group A(mobile resin repair group), Group B(Z350 mobile resin + glass fiber pile repair group) and Group C(Z350 mobile resin + glass fiber pile + full crown restoration group). Comparative observation was conducted under the unified evaluation criteria. Results After 2 years’ observation,there was significant difference between Group A and Group B (P<0.05) . And there was no significant difference between Group C and Group B (P>0.05) . Conclusion The fiber pile can significantly improve the strength of the residual dental tissue of the severe wedge-shaped defect, and significantly improve its anti-foldability. But there is no significant effect on the repair of the severe wedge defect with the full crown, which deserves further discussion.
