Three-dimensional differences between intraoral scans and conventional impressions of edentulous jaws: A clinical study

摘要

Statement of problem. Using intraoral scans for removable dentures has been questioned because of a suggested lack of accuracy. However, data regarding the accuracy of digital intraoral complete-arch scans are sparse, present some methodological issues, and mostly come from in vitro studies on dentate casts, which are very different from edentulous arches.
