The professional society that released the guideline (Deutsche Gesellschaft für Implantologie e.V.) invited participants to attend a new guideline conference in September 2019. The results from this conference, where representatives from a total of 15 professional societies participated, have now been published in the form of a recent update. In preparation for the update, a systematic literature search in the relevant databases was repeated and the retrieved literature was assessed; this resulted in the inclusion of 11 additional studies. Exclusively titanium implants were examined. The superstructures were fixed (one-piece, screw-retained) or removable (mostly bar-retained). The key recommendations relating to the number of implants were checked and confirmed. In total, 14 new recommendations and statements were included; many of these are related to fixed restorations on 4 implants. AID - 3667937
