The success of conventional impression procedures demands various factors including apt tray and materials, flawless manipulation procedures and patient cooperation. A digital impression procedure is an advanced technique to get rid of the troublesome associated with traditional impression procedures. However, the practicability and accuracy of digital technology can be perceived by comparing all aspects of both conventional and digital impression procedures. This review is aimed to compare various facets of conventional and digital dental impression procedures. A comprehensive literature search has been conducted from published articles using internet search databases and with keywords. From the archived articles, 25 most relevant articles selected for comparative study. The results support the use of digital technology for accurate impression.
