About this trial
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.
Eligibility criteria
Qualifiers
Minimal age of 22 years old.
No general medical condition which represents a contraindication to implant treatment
Good oral hygiene (PII ≤ 20%), and healthy periodontal tissues (BOP≤ 20%)
Two adjacent-teeth gap in posterior maxilla or mandible arch (first premolar, second premolar, first molar, second molar) with an osseointegrated regular or wide-diameter bone-level implant in a prosthetically correct position to allow occlusal screw-retention. Free-end edentulous gaps can also be included
Disqualifiers
Severe bruxism or clenching habits
Patients with inadequate oral hygiene or persistent intraoral infection
Women who are pregnant or breast feeding at the day of inclusion
Smokers exceeding 15 cigarettes / day, or equivalent; patients chewing tobacco
Trial design
Treatments tested in this trial
- Monolithic zirconia screw retained implant-supported cantilever reconstruction supported by titanium base abutments, in a full digital workflow (ZR-TiB)
- porcelain fused-to metal screw retained implant-supported cantilever reconstruction supported by a gold-abutment, in a conventional workflow (PFM-GA)
