Before the introduction of version R1800, only CORRELATION was available to the Cerec user for veneer design, and recourse had to be taken to the earlier Cerec 3 program for constructive veneer production. The software R1800 now alsomakes a tooth database available for veneers and allows copying and free insertion of any acquired tooth forms. With the R2005 version, the editing possibilities for designing veneers were further optimized; copying, mirroring and insertion of crowns were also facilitated. The situation-related selection of the CORRELATION designmethod, DENTAL DATABASE, and REPLICATION are described and assessed by reference to clinical situations.
