Since the DICOM (Digital Imaging and COmmunication in Medicine) data of CT (Computed Tomography) is digital data, the implant treatment is highly compatible with digital dentistry and digital technology has been introduced from a relatively early stage. In addition to simulation software, guide surgery and safe surgery using a navigation system, the superstructure of the implant using CAD/CAM has also become widespread today.
Diffusion of optical impressions extends the digital workflow not only to laboratory but also to clinical procedures, and in some systems, from the optical impression to the construction of the superstructure of the implant are systematically developed, and the full digital workflow It can be said that top-down treatment by approach has come close to completion.
On the other hand, it is also true that digital workflows related to optical impressions are less flexible than conventional workflows, and there are some restrictions, such as highest level of accuracy obtained by conventional workflows is not guaranteed. In this article, we will present changes and utilization of optical impression in implant treatment and discuss future development with focus on technical limitations currently faced.
