Optical impression and provisional prosthesis: Proposal for a new approach
April 21, 2019
The widespread use of intraoral optical impressions and constant improvements in dental computer-aided design (CAD) software today allow the practitioner to manage various kinds of clinical situations, from the simplest to the most complicated, by using different types of dedicated equipment (camera software, processors and, more recently, 3D printers) as part of a completely digital workflow. Arch scanning methods using intraoral scanners yield impressions that are comparable to those obtained with traditional equipment in terms of clinical precision because they eliminate the variations caused by the user, reduce the readjustment processing time and costs, and improve patient satisfaction and comfort.
