Study Summary

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

Inclusion

Inclusion Criteria:

  • 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, secondpremolar, first molar, second molar) with an osseointegrated regular or wide-diameterbone-level implant in a prosthetically correct position to allow occlusalscrew-retention. Free-end edentulous gaps can also be included
  • Presence of antagonist occlusal units

Exclusion

Exclusion Criteria:

  • 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
  • Unable or unwilling to cooperate for the trial period
  • Estimated cantilever crown mesial-distal length > 10 mm
  • Estimated implant crown height (from implant platform to occlusal contact points) > 15mm
