27、CAD systems differ from each other, thus creating confusion among dentists and dental technicians. In order to overcome these ambiguities, it was decided to prepare an International Standard for terminology used in the process chain for CAD/CAM systems.For the purposes of illustrating the logic sequ
28、ence of the process chain for CAD/CAM systems, a flow chart of this process chain is shown in Annex A.EN ISO 18739:2016 (E) DIN EN ISO 18739:2016-11 5 1 ScopeThis International Standard specifies terms, synonyms for terms and definitions used in the process chain for CAD/CAM systems in dentistry.2 N
