This paper presents development of various CEREC systems and the clinical procedures of development of dental restorations with that system. CEREC system is entirely new approach in the process of replacement of lost hard dental tissue. It is a product of a desire for estetic reconstruction of stomatognathic system with the merger of technology which is a product of a computer system development. The clinical procedures for dental tissue replacement has been significantlly simplified in the dental surgery since the implementation of CEREC system for development of ceramic inlays and fassets in clinical practice. With this approach the results achieved are the same or even better in comparison to classic laboratory procedure. Together with good relationship between dentists and patients CEREC system represents a therapeutical tool which estetically satisfies even the most critical patients and meets demands of the modern dental science.
