目的：比较玻璃纤维桩加树脂、铸造镍铬金属桩、无桩固定对磨牙残根残冠修复的效果。方法选取我院口腔科收治的牙冠缺损患者119例患者（126颗牙）的临床资料，根据治疗方案分为玻璃纤维桩树脂核组40例（42颗牙）、铸造镍铬金属桩组40例（42颗牙）、无桩固定位组各39例（42颗牙），比较三组患者总成功率及咀嚼效能有效率等指标。结果玻璃纤维桩树脂核组与铸造镍铬金属桩、无桩固定位组患者的总成功率分别为83.33%、80.95%、85.71%，P＞0.05；三组患者的脱落发生率、冠折、根折、牙龈炎及全冠松动的发生率均较低， P＞0.05；三组患者术后0.5年的有效率比较，P＞0.05；术后1年的有效率比较，P＞0.05。结论在规范修复技术的基础上，玻璃纤维桩加树脂、铸造金属桩核、无桩固定位均能够达到修复效果，治疗后1年内留存率较高。%Objective To compare the glass fiber pile resin, cast nickel-chromium metal piles, pile no fixed residual roots and crowns of the molars effect. Methods Admitted to our hospital dentistry crowns defects were 119 cases of patients (126 teeth) clinical data, according to the treatment program is divided into glass ifber post and resin core group of 40 patients (42 teeth), cast nickel-chromium metal posts set 40 patients (42 teeth), no pile holding position 39 patients (42 teeth), three groups of patients assembly power and efifciency of masticatory efifciency and other indicators. Results Glass ifber post and resin core group and cast nickel-chromium metal piles ifxed bit group of patients stakeless assembly power were 83.33%, 80.95%, 85.71%, P>0.05, loss occurrence rate of three groups of patients, crown fracture, root fracture, gingivitis and loose crown were low, P>0.05, postoperative three groups of half year effective rate, P>0.05, one years after the effective rate, P>0.05. Conclusion On the basis of norms repair technology, glass ifber pile and resin, metal post, stakeless ifxed position are able to repair effect one year after treatment retention rate is high.
