Abstract
:1. Introduction
2. Materials and Methods
3. Results
4. Discussion
5. Conclusions
- In everyday dentistry, both closed systems and open systems can be used to achieve an acceptable marginal gap (<120 µm) for ZLS CELTRA® DUO single crowns.
- No significant difference was found regarding the marginal gap when comparing ZLS CELTRA® DUO single crowns produced by closed systems or open systems and cemented with Gcem One self-adhesive resin cement.
- There was a significant difference between cementation with Temp-bond and Gcem One self-adhesive resin cement regarding the marginal gap (p < 0.0005).
