Clinical Trial Summary

The study aims to evaluate the clinical performance (implant and prosthetic survival/ success rates) of a novel implant-supported fixed dental prosthesis design: the dual-cantilevered single implant bridge (T-Bridge) made out of monolithic zirconia bonded to a titanium base abutment (Variobase abutments)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Implant and prosthetic success	Primary outcome parameter: implant and prosthetic success; Implant success and survival rate will be defined according to established criteria (Buser et al. 1991): A surviving implant and/or restoration is defined as are in place at the time of the follow-up.	10 years
Primary	Implant and prosthetic survival	Implant success and survival rate will be defined according to established criteria (Buser et al. 1991): A surviving implant and/or restoration is defined as are in place at the time of the follow-up.	10 years
Secondary	Implant and prosthetic complications	Biological and/or Technical Implant and prosthetic complications	10 years
