Authors' objectives: To assess the effectiveness, cost-implication, safety, organisational and social issues related to digital dental impression.

Authors' results and conclusions: There was limited in-vivo retrievable evidence to suggest digital dental impression was found to be comparable to conventional impression for lower and upper arch anteroposterior length, lower and upper intercanine distance, lower and upper intermolar distance, complete-arch implant-supported restoration and marginal/ internal fit. There were also limited evidence retrieved to suggest that digital dental impression was more comfortable, preferred by patients and also operators and had shorter procedure/ chairside time compared to conventional impression. Patients perceived that digital dental impression was faster compared to conventional impression. Meanwhile, operators perceived that digital dental impression was less difficult. There was no evidence retrieved on the safety and cost-effectiveness of digital dental impression.

Authors' recommendations: Based on the above review, digital dental impression may be used for dental procedures.

Authors' methods: Electronic databases were searched through the Ovid interface: Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R) 1946 to Feb 2020, EBM Reviews - Cochrane Central Register of Controlled Trials – Jan 2020, EBM Reviews - Cochrane Database of Systematic Reviews - 2005 to Feb 2020, EBM Reviews - Health Technology Assessment – 4th Quarter 2016, EBM Reviews – NHS Economic Evaluation Database 1st Quarter 2016.
