An Overview of Systematic Reviews and Meta-analyses Evaluating Different Impression Techniques for Implant-Supported Prostheses in Partially and Completely Edentulous Arches.

Within an overall moderate methodologic quality, the digital implant impressions showed favorable outcomes in terms of accuracy, time efficiency, and patient preference in partially edentulous arches involving three or fewer implants. However, the accuracy of full-arch digital impressions involving multiple implants is not satisfactory and needs significant improvements. Hence, future studies following stringent guidelines and robust methodology are recommended to substantiate the findings of this overview and provide a high level of evidence.
