Computer-aided dental manufacturing technologies used in fabrication of metal frameworks

Metal alloys have been used for many years as framework material of dental restorations. The conventional lost-wax and casting method, which was very popular in fabrication metal frameworks, are now being replaced by computer-aided manufacturing technologies. Computer-aided methods offer advantages, such standardization quality manufacturing, precise fit restorations, improved mechanical strength. Digital technologies frameworks simply classified subtractive additive systems, each their own subdivisions, show differences the technology. This review summarizes systems terms use practice, disadvantages provides clinical recommendations.
