The primary objective of this systematic review was to
investigate the survival of full-coverage restorations fabricated by using
digital impressions (DIs) versus that of those fabricated by using conventional
impressions. The authors also compared secondary outcomes of marginal and
internal fit and occlusal and interproximal contacts. The authors conducted a
systematic literature search in multiple databases to identify clinical trials
with no restrictions by publication type, date, or language. The authors
assessed study-level risk of bias and outcome-level strength of evidence. The
authors performed a meta-analysis by using a random-effects model.
