摘要目的研究大面积龋损儿童乳磨牙修复中金属预成冠的应用效果。方法选取南通大学附属南通口腔医院于2018年1月—

2021年2月收治的172例大面积龋损患儿为研究对象，按治疗方案不同分为对照组（86例）与治疗组（86例），对照组行固化树

脂填充修复，治疗组行金属预成冠修复，对比两组修复效果、修复满意度及咀嚼功能。结果修复总有效率比较，治疗组

97.67%高于对照组84.88%，差异有统计学意义（χ=8.837，P0.05）；修复总满意率比较，治疗组96.51%高于对照组82.56%，差

2

异有统计学意义（χ2=8.935，P0.05）；治疗组修复后3个月咀嚼效率、咬合力均高于对照组，差异有统计学意义（t=9.812、8.387，

P0.05）。结论大面积龋损儿童乳磨牙修复中应用金属预成冠，可促进修复效果提高，并提高修复满意度。
