[摘 要]目的 探究針对牙冠大面积缺损采用多根管玻璃纤维桩联合全瓷冠进行修复的效果。方法 选择2017年10月-2022年10月北京市海淀区花园路社区卫生服务中心口腔科收治的100例牙冠大面积缺损患者为研究对象，随机分为对照组和研究组，各50例。对照组采用金属桩钴铬烤瓷冠修复，研究组采用多根管玻璃纤维桩联合全瓷冠修复，比较两组咀嚼效率、修复效果、修复成功率、龈沟液MMP2、ICAM1、ALP水平及并发症发生情况。结果 研究组修复后6个月咀嚼效率高于对照组（P<0.05）；研究组修复完整度、颜色匹配、边缘适合性占比均高于对照组（P<0.05）；研究组修复成功率为96.00%，高于对照组的84.00%（P<0.05）；研究组修复后6个月龈沟液MMP2、ICAM1、ALP水平均优于对照组（P<0.05）；研究组并发症发生率为4.00%，低于对照组的20.00%（P<0.05）。结论 多根管玻璃纤维桩联合应用全瓷冠修复牙冠大面积缺损的效果良好，修复成功率较高，生物相容性良好，可有效提升患者的咀嚼效率，是一种安全且可靠的修复方法，值得临床应用。

[Abstract]Objective To observe the effect of glass fiber post with multiple root canal combined with all-ceramic crown in repairing large area defect of crown. Methods A total of 100 patients with large area defect of crown admitted to the Department of Stomatology， Huayuan Road Community Health Service Center， Haidian District， Beijing from October 2017 to October 2022 were randomly divided into control group and study group， with 50 patients in each group. The control group was repaired with metal post cobalt chromium porcelain crown， and the study group was repaired with glass fiber post with multiple root canal and allceramic crown. The masticatory efficiency， repair effect， repair success rate， gingival crevicular fluid MMP2， ICAM1， ALP levels and complications were compared between the two groups. Results The masticatory efficiency of the study group was higher than that of the control group at 6 months after repair （P<0.05）. The proportion of repair integrity， color matching and edge suitability in the study group was higher than that in the control group （P<0.05）. The repair success rate of the study group was 96.00%， which was higher than 84.00% of the control group （P<0.05）. The levels of MMP2， ICAM1 and ALP in gingival crevicular fluid in the study group were better than those in the control group at 6 months after repair （P<0.05）. The incidence of complications in the study group was 4.00%， which was lower than 20.00% in the control group （P<0.05）. Conclusion The effect of glass fiber post with multiple root canal combined with all-ceramic crown in repairing large area defect of crown is good， the success rate of repair is high， and the biocompatibility is good. Meanwhile， it can effectively improve the masticatory efficiency of patients. It is a safe and reliable repair method， which is worthy of clinical application.

牙冠大面积缺损（large area defect of crown）一般是因外伤、硬物咀嚼等造成，严重影响牙齿美观性及咀嚼功能，也可能引起牙周组织病变疾病等[1]。如今，人们对牙齿美观性愈加重视，临床修复中大多应用金属桩钴铬烤瓷冠，但由于其存在较强刚性，可能发生断裂、金属腐蚀等情况，无法保证修复体使用寿命。玻璃纤维桩具有强度高、抗腐蚀性强等特点，同时，全瓷冠的美观性良好，目前已广泛应用于牙体修复。本研究旨在探究多根管玻璃纤维桩联合全瓷冠修复牙冠大面积缺损磨牙的效果，现报道如下。
