近年来,随着现代粘接技术及全瓷材料性能的不断提高,使具有美观及良好生物相容性的瓷修复体能够更大范围地应用于临床;而计算机辅助设计与制造等工艺的迅速发展与普及,也使全瓷高嵌体的优点得以展现;尤其是椅旁CAD/CAM系统制作全瓷高嵌体因具有美观、省时、舒适、精度高等优势,在牙体缺损修复中的应用日渐增多。笔者应用椅旁CAD/CAM系统制作全瓷高嵌体修复失髓牙体缺损患牙,并观察修 In recent years, with the continuous improvement of modern bonding technology and the performance of all-ceramic materials, porcelain prostheses with good appearance and good biocompatibility can be applied to a wider range of clinical applications. However, the rapid development of computer aided design and manufacturing processes Development and popularization, but also to show the advantages of all-ceramic inlays; especially the chair-side CAD / CAM system for the production of all-ceramic high inlay has the advantages of beautiful, time-saving, comfortable and high precision, Increasing application. I use the chair next to the CAD / CAM system for the production of all-ceramic inlays to repair misaligned tooth defects with teeth, and observe the repair
