Abstract

Background. Implant-supported cantilever prostheses enable a more straightforward rehabilitation and may be a therapeutic option to reduce treatment morbidity, costs, and time. This study evaluated the clinical outcomes of fixed implant-supported partial dentures made of monolithic zirconia with a cantilever design to replace missing posterior teeth. Methods. Fifteen partially edentulous patients received 34 implants and were provided with 16 zirconia fixed partial prostheses (FPPs) with one cantilever extension replacing mandibular or maxillary missing posterior and lateral teeth. Patients were re-examined for up to 4 years. Patient ages ranged from 41 to 65 years, with a mean age of 53±12 years; 47% were female, and 53% were male. The patients were observed for a mean period of 42±6 months with a minimum of 3 years and a maximum of 4 years. Results. Peri-implantitis was observed in two cases. No chipping or fracture of any FPP was detected. Loosening of the abutment screw was a technical complication in one case. The rehabilitation survival rate was 100%. Implant-supported zirconia FPP with one mesial cantilever extension provides an aesthetic, functional treatment alternative to replace missing molars, premolars, and canines. These excellent clinical outcomes occurred over a mean observation time of 42±6 months. Conclusion. Using monolithic zirconia milled with CAD-CAM technology might be an alternative to the metal-ceramic restoration in implant-supported FPP with one cantilever.

  • Single-unit zirconia crowns offer excellent tissue biocompatibility, high mechanical strength, and reliable digital processing capabilities.

    “This material offers excellent tissue biocompatibility, high mechanical strength, and reliable digital processing capabilities [27–29].”

    From Implant-supported fixed prosthodontic treatment for ectodermal dysplasia: a case report (2026) · cites this paper as [29]

    The Discussion reports that the studied zirconia prostheses withstood masticatory forces without mechanical failure, and the Introduction describes benefits of digital processing. The paper studies implant-supported cantilevered fixed partial dentures, not single-unit crowns, and the passages do not establish excellent tissue biocompatibility. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • After appropriate polishing, zirconia surface roughness is lower than that of metal or rough ceramics, reducing plaque accumulation and the risk of peri-implant mucositis.

    “After appropriate polishing, the surface roughness is lower than that of metal or rough ceramics, reducing plaque accumulation and the risk of peri-implant mucositis”

    From Implant-supported fixed prosthodontic treatment for ectodermal dysplasia: a case report (2026) · cites this paper as [29]

    The Methods and Discussion contain no assessment of polishing, comparative surface roughness, plaque accumulation, or peri-implant mucositis; searches for those terms found no supporting passage. The Discussion says there is no scientific evidence that a material difference minimizes peri-implantitis, but that is a distinct condition and does not directly contradict the mucositis claim. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
