Relationship between analog and digital technology

Current status and future prospectives of prosthetic fabrication using digital technology

Abstract

Now these days, fixed prosthodontic treatment requires digital awareness in daily clinical work. When preparing the abutment tooth for a CAD/CAM crown, clinical errors will occur if the abutment shape is not appropriate for CAD/CAM technique, it will directly affect to problems. Furthermore, when a monolithic crown is selected for the anterior tooth, it is not possible to achieve the shade matching required for prosthodontists. Therefore, there are many points of confusion regarding fabrication methods and material selection, such as whether to choose analog or digital. In addition, the boundary between digital and analog is not clear in the fabrication process. Finally, brilliant result can be obtained not only by digital technology, but also for using analog technology in combination.
