    [摘要] 目的 探討玻璃纤维桩氧化锆全瓷冠修复前牙牙体缺损的效果及其对咀嚼能力的影响。 方法 选取2017年1～10月河北省唐山市协和医院口腔科收治的102例(128颗牙)前牙牙体缺损患者作为研究对象，采用随机数字表法将其分成观察组47例(60颗)和对照组55例(68颗);观察组给予玻璃纤维桩氧化锆全瓷冠修复，对照组给予金属桩钴铬烤瓷冠修复;观察两组修复成功率、修复效果、牙周、龈沟液、咀嚼效率和患者满意度。 结果 两组修复成功率比较，差异无统计学意义(P > 0.05);观察组修复体完整度、颜色匹配、边缘适合性、边缘着色、牙龈状况合格人数均多于对照组，差异有统计学意义(P 0.05);观察组修前复后GCF、ALP水平比较，差异无统计学意义(P > 0.05)，对照组修复前后GCF、ALP水平比较，差异有统计学意义(P 0.05)，且明显高于对照组(P 0.05). The number of eligible patients on restoration integrity， color matching， marginal fitness， marginal staining and gingival condition of the observation group were more than those of the control group， and the differences were statistically significant (P 0.05). There were no significant differences in the levels of GCF and ALP before and after repair in the observation group (P > 0.05); there were significant differences in the levels of GCF and ALP before and after restoration in the control group (P 0.05) ......
