[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龋临床效果相当。结论：In-Ceram渗透陶瓷具有较好的强度，抗磨损、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。

Abstract:ObjectiveTo compare the clinical effects on the IPS-Empress2 cartable ceramic and In-Ceram infiltratedceramicsall-ceramic crown to be repairedthe anterior teeth.MethodsTo choose 100 patients who chose the all-ceramic crown to be repaired the anterior teeth, and according to the different repairing ways to divided into observation group(IPS-Empress2 cartable ceramic) and control group (In-Ceram infiltratedceramics),50 cases for each group.Be compared the repairing effects and the degree of satisfaction.Results4 cases in the observation group had cracks, but no jackknifing phenomenon. The control group no crack and jackknifing phenomenon,but the observation group repairing color effects were better than the control group,and clinical effects on the repairing figure form of the verge fitness and the round of the caries of the teeth were to some tune.Conclusion In-Ceram infiltrated ceramics has the best strength, the antifoaming and the ant flex cracking capability are best,but the color of IPS-Empress2 is the most beautiful than In-Ceram. So using in the clinical should be according to the truth to be choosing the suit all-ceramic crown to be repaired them.
