To Compare Cemented Versus Screw-retained Implant-supported Single Crowns With Customized Zirconia Abutments
Not Applicable
Completed
- Conditions
- Implant-supported Single Crowns
- Registration Number
- NCT01644630
- Lead Sponsor
- University of Zurich
- Brief Summary
The aim of this study is to test whether or not the use of screw-retained implant crowns on customized zirconia abutments results in biological, technical and esthetic outcomes similar to those obtained with cemented all-ceramic crowns on customized zirconia abutments, both made with a computer-aided design and manufacturing procedure (CAD/CAM).
The null-hypotheses is that marginal bone level change is equal at screw-retained and cemented crowns
