Digitalization has become part and parcel of contemporary prosthodontics with the probability of most of the procedures being based on the digital techniques in the near future. This digital revolution started in the latter half of the 20th century by converting analog objects/signals into digital bits and bytes. Recent developments in all-ceramic materials and systems of computer-aided designing and computer-aided manufacturing (CAD/CAM), copy milling, and so forth offer excellent esthetics and superb biocompatibility. Copy milling system for ceramics enables milling of the zirconia cores of all-ceramic restorations precisely and also if this system is properly used the procedure for fabricating all-ceramic restorations can be substantially simplified. This case report presents fabrication of all-ceramic Maryland Bridge and post-core with a copy milling system for esthetics and preservation of integrity of tooth. For both of the patients, the use of biologic, all-ceramic, copy-milled restorations resulted in clinical success and recovered function and esthetics.
数字化已成为当代口腔修复学不可或缺的一部分，在不久的将来，大多数操作都有可能基于数字技术。这场数字革命始于20世纪后半叶，通过将模拟对象/信号转换为数字位和字节来实现。全陶瓷材料以及计算机辅助设计与计算机辅助制造（CAD/CAM）、复制铣削等系统的最新发展提供了出色的美学效果和卓越的生物相容性。陶瓷复制铣削系统能够精确地铣削全陶瓷修复体的氧化锆核，并且如果正确使用该系统，全陶瓷修复体的制作过程可以大大简化。本病例报告介绍了使用复制铣削系统制作全陶瓷马里兰桥和桩核，以实现美观并保持牙齿完整性。对于这两位患者而言，使用生物性全陶瓷复制铣削修复体均取得了临床成功，并恢复了功能和美观。
