Manual copy- milling, an alternative to cad/cam method for zirconia restorations

Zirconia ceramic is used as a metal substitute and is behind development of digital dentistry, which is based on computer-aided design and computer-aided manufacturing and helps decreasing laboratory work, reducing time and chance of error but it is a sensitive technique which also needs expensive unit. On the other hand, copy milling technique is based on a manually designed copings or frameworks with wax or composite that will be duplicate based on pantographic principle. It is an easy and economical method to produce zirconia frameworks for dental restorations. The purpose of this article is to present the principle, the advantages and the implementation of this technique, through a clinical case.
