About this trial

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)

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Trial outcomes

Primary outcomes

1

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.

Time frame
10 years
2

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.

Time frame
10 years

Secondary outcomes

1

Implant and prosthetic complications

Biological and/or Technical Implant and prosthetic complications
