Focused questions on (a) short posterior dental implants (\u22646\u00a0mm), (b) narrow diameter implants, (c) implant design (tapered compared to a non\u2010tapered implant design), and (d) medication\u2010related dental implant failures were addressed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>Four systematic reviews were prepared in advance of the Consensus Conference and were discussed among the participants of Group 1.

In contrast, it is concluded that narrow diameter implants with diameters of less than 2.5\u00a0mm exhibited lower survival rates compared to standard diameter implants.
