- A consensus based on patients’ perceptions as to whether to use overdentures or fixed prostheses to rehabilitate mandibular edentulous arches is limited.
- Evidence provided by implant-supported mandibular overdenture research on different loading protocols is important. However, methodological inconsistency, as well as inadequate reporting of results, hampers a consistent decision in terms of clinical applicability.
- A consensus on whether to use an adhesive layer on glass-ceramics after etching with hydrofluoric acid and applying a silane-coupling agent is lacking.
- Consensus is lacking regarding the influence of the maxillary dentition on the survival rate of a mandibular metal-resin implant-supported fixed complete denture (MRISFCD) with distal cantilevers.
