【摘要】 目的：探討玻璃纖維樁在老年上頜前牙殘根殘冠修復的應用價值。方法：選取2016年1月-2017年5月于本院診治的60例上頜前牙殘根殘冠修復患者，按照隨機數(shù)字表法將其分為觀察組（n=30）和對照組（n=30）。觀察組給予玻璃纖維樁進行殘根殘冠修復，對照組給予金屬樁進行殘根殘冠修復，治療后隨訪1年，比較兩組臨床療效、牙齦指數(shù)（GI）和修復齒出血指數(shù)（SBI）、修復效果以及不良反應發(fā)生率。結果：治療后，觀察組治療成功率高于對照組（P<0.05）;觀察組GI、SBI以及不良反應發(fā)生率均低于對照組（P<0.05）;觀察組的顏色匹配率以及邊緣適合率均高于對照組（P<0.05），而兩組修復體完整度比較差異無統(tǒng)計學意義（P>0.05）。結論：玻璃纖維樁應用于修復老年上頜前牙殘根殘冠的臨床效果較好，不僅可改善患者牙齦狀態(tài)，保持長期修復牙齒功能與美容效果，而且降低了不良反應發(fā)生率，臨床應用價值較高。

【Abstract】 Objective：To explore the application value of glass fiber post in the restoration of residual root and crown of maxillary anterior teeth for elderly patients.Method：A total of 60 elderly patients with maxillary anterior residual root and crown repair that treated in our hospital from January 2016 to May 2017 were selected.According to the random number table method，they were divided into observation group（n=30）and control group（n=30）.The observation group was treated with glass fiber post for restoration of residual roots and crowns，while control group was treated with metal post for restoration of residual roots and crowns，after 1 year follow-up，the clinical efficacy，gingival index（GI）and dental hemorrhage index（SBI），repair effect and incidence of adverse reactions between two groups were compared.Result：After treatment，the success rate of observation group was higher than that of control group（P<0.05）.The incidence of GI，SBI and adverse reactions in observation group were lower than those of control group（P<0.05）.The color matching rate and edge matching rate of observation group were higher than those of control group（P<0.05）.The restoration integrity in two groups was compared，the difference was not statistically significant（P>0.05）.Conclusion：The clinical effect of glass fiber post to restore old maxillary anterior residual root and crown is better，it can not only improve patients gingival state，maintain long-term function and cosmetic effects of restorative teeth，but also reduce the incidence of adverse reactions，the clinical value of which is higher.

前牙殘根殘冠不僅影響患者的美觀，還影響患者牙齒的正常功能，還易引起根尖周炎等并發(fā)癥，大大降低了患者的生活質量[1]。隨著生活水平的提高，老年上頜前牙殘根殘冠的發(fā)生率逐年上升。目前臨床對于殘根殘冠的治療主要是樁核冠修復治療，樁核材料對牙體修復的效果至關重要[2-3]，以往多采用金屬樁，金屬樁核有良好物理機械性能，但其彈性模量高于牙體組織，當修復體受到較大牙合力時，易引發(fā)根折，且其具有金屬離子細胞毒性，容易腐蝕變色[4]。近年來，玻璃纖維樁作為新型樁核材料應用于臨床，其具有良好的生物相容性、強度高、透光性好，操作簡便其彈性模量與牙本質相近[5-6]，且據(jù)目前的研究顯示，使用纖維樁后出現(xiàn)牙根斷裂的概率較小[7]。本次研究主要分析玻璃纖維樁在老年上頜前牙殘根殘冠修復的應用價值，現(xiàn)報道如下。
