Overview
Brief Summary
To report the clinical and radiographic outcomes of implant-supported fixed dental prostheses with full-ceramic cantilever extensions (FDPCs) after a function time ≥ 12 months.
Detailed Description
Patients with full ceramic FDPCs in anterior and posterior areas will be clinically and radiographically re-evaluated. Mesial and distal radiographic marginal bone levels (mBLs) from baseline (i.e. delivery of FDPC) to the follow-up examination were calculated and compared between implant surfaces adjacent to and distant from the cantilever extension. Implant survival rate (%), pocket probing depth (PPD), presence/ absence of bleeding on probing (BoP) and presence/absence of mechanical/technical and biological complications were recorded.
