Clinical outcomes and complications of tooth- and implant-supported lithium (di)silicate based single crowns: an overview of systematic reviews

Lithium (di)silicate ceramics provide an aesthetically and mechanically reliable option for single crowns in both anterior and posterior regions. Clinical evidence supports their excellent short- and medium-term survival with minimal antagonist wear, particularly when proper surface finishing protocols are followed. However, clinicians should be aware of material-specific differences among commercially available lithium (di)silicate systems and be cautious when extrapolating clinical results obtained from specific products to others. In light of limited long-term clinical data, practitioners should communicate both the well-documented short- to medium-term benefits and the remaining uncertainties regarding long-term performance. This overview also emphasizes the importance of critical appraisal of systematic reviews and encourages careful interpretation of pooled results, particularly in the presence of high heterogeneity or inappropriate data aggregation.
