Introduction: The aim of this systematic review was to assess the literature reporting on the failure rates, survival rates and complication rates and patient reported outcome measures (PROMs) of anterior full (FC) or partial (PC) coverage single tooth restorations after a mean observation period of at least 3 years.

Methods: Systematic search was conducted using the electronic databases: MEDLINE, EMBASE and Cochrane library. Data regarding survival (restoration failure) and complication rates and PROMs were extracted and presented descriptively.

Results: Altogether 42 studies were included in the analysis (28 with FC, 12 with PC and 2 with both types of restorations). For FC restorations the estimated annual failure rate was 0.72 (95%CI: 0.33-1.57), resulting in a 5-year survival rate of 96.4% (95%CI: 92.4-98.3). For PC restorations, the estimated annual failure rate was 0.62 (95%CI: 0.27-1.46), resulting in a 5-year survival rate of 96.9% (95%CI: 93.0-98.7). There was no significant difference between the groups regarding survival or technical complications, while significantly fewer biological complications were observed with PC compared to FC restorations (test for subgroup differences, p=0.01).

Conclusions: FC and PC restorations showed high 5-year survival rates but the teeth restored with FC restorations may be more prone to biological complications.
