An observational study in Dental Implant Failed, Prosthesis Failure and Peri-Implantitis, sponsored by University of Bern. Completed at 1 site in Switzerland. Open to participants aged 18 Years to 99 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-01-22.
Sponsored by University of Bern · Observational
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.
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.
119 studies on the registry are indexed under Prosthesis Failure; 35 are open to participants now.
This study's enrollment of 35 is below the median of 119 across 49 observational studies indexed under Prosthesis Failure.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Ran from Jan 2023 to primary completion in Sep 2023, 8 months.
Of 28 observational studies under Prosthesis Failure, half reached primary completion within 181 months of starting (the median), counting those still running; a quarter within 57 and three quarters within 184. This study's 8 months is below that.
