1、两种陶瓷修复前牙的临床观察两种陶瓷修复前牙的临床观察［摘要］目的：比较IPS-Empress2铸造陶瓷与In-Ceram渗透陶瓷全瓷冠两种不同修复方式在前牙修复中的临床效果。方法：选择行全瓷冠修复前牙患者100例，并根据不同的修复方式分为观察组(IPS-Empress2铸造陶瓷)和对照组(In-Ceram渗透陶瓷)，每组各50例。并对两组的修复效果和患者满意度进行比较。结果：观察组有4例出现裂纹，没有折裂现象；对照组未出现裂纹、折裂现象，但观察组的修复颜色较对照组的效果好，而两组的修复体形态的边缘适合度和修复体周围龌临床效果相当。结论：In-Ceram渗透陶瓷具有较好的强度，抗磨损、

2、抗折裂能力强，而IPS-Empress2的颜色则比In-Ceram全瓷更美观。因此临床上的使用应根据实际的情况选择适合的全瓷材料进行修复。［关键词］前牙；修复；IPS~Empress2铸造陶瓷；In-Ceram渗透陶瓷；临床观察［中国分类号］R783［文献标识码］A［文章编号:1008-6455(2011)03-0465-03ClinicalobservationoffrontteethberepairedbytwoceramicsWANGYu-dongl,ZHA0Shu-hongl,LIANKe-qian2,CHENKail,LIZhang-wei1(1.DepartmentofS
