A technique for the fabrication of copy milled ceramic restorations has been presented. Both direct and indirect fabrication techniques of inlays, onlays, veneers, and crowns are possible. A copy milling machine can mill accurately fitting restorations with a marginal gap of 50 microns. The machine uses premanufactured porcelain blanks, which have improved physical properties over conventional porcelains used in standard techniques. Recently, the ability to mill In-Ceram crowns from presintered alumina blocks and Spinell crowns from alumina/magnesia blocks has been added to the system. The copings are veneered with aluminous porcelain as in the conventional In-Ceram technique.
本文介绍了一种复制铣削陶瓷修复体的制作技术。嵌体、高嵌体、贴面和全冠的直接和间接制作技术均可行。复制铣床能够精确铣削出边缘间隙为50微米的贴合修复体。该机器使用预制的瓷块,其物理性能优于标准技术中使用的传统瓷器。最近,该系统增加了从预烧结氧化铝块铣削In-Ceram全冠以及从氧化铝/氧化镁块铣削尖晶石全冠的能力。如同传统In-Ceram技术一样,基底冠用含铝瓷进行饰面处理。
