Two-unit Cantilever Implant Prostheses Made of Monolithic Zirconia or PFM
Recruiting now · Not applicable
Conditions studied: Jaw, Edentulous, Partially, Missing Teeth
In brief
The aim of is to compare the survival rate and technical outcomes of cantilever implant-supported fixed denture prosthetics (cFDPs) made either out of monolithic zirconia bonded to a titanium base in a digital workflow, or porcelain fused-to metal using a gold abutment in a conventional workflow. In addition, biological outcomes, wear patterns, PROMs and time efficiency will be recorded. The null hypothesis is: the reconstruction type does not influence the survival rate and technical outcomes of 2-unit implant-supported cFDP.
