In immediate full\u2010arch rehabilitations requiring tilted posterior implants, anatomical constraints may not allow such spacing. When implants are placed in close proximity, conventional angulated multiunit abutments (MUAs) can lead to prosthetic interference and compromised mechanical resistance. This case report describes the management of two tilted implants with an IID &lt;1\u2009mm using a novel eccentric MUA. Implant spacing was precisely quantified using a superimposition\u2010based digital workflow.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>A 72\u2010year\u2010old woman underwent extraction and immediate placement of six implants in the maxilla for full\u2010arch rehabilitation. Two posterior maxillary implants were positioned less than 1\u2009mm apart. This prevented the use of conventional angulated MUAs. An eccentric MUA providing a 3.6\u2009mm horizontal offset enabled restoration of adequate prosthetic spacing. A definitive prosthesis with a titanium laser\u2010welded framework and composite veneering was fabricated and delivered 24\u2009h after surgery. At the 6\u2010year follow\u2010up, no biological or major mechanical complications were observed. In the narrow interimplant area, bone extended above both implant necks and the papilla persisted. After unscrewing the prosthesis, digital intraoral scanning with scan bodies and STL superimposition allowed digital measurements of the IID.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This 6\u2010year case report documents the use of a noncustomized eccentric MUA with a 3.6\u2009mm offset as a practical solution for managing an IID &lt;1\u2009mm. This was achieved without compromising prosthetic function or papilla formation. The crestal bone between the close implants appeared to remain stable over the follow\u2010up period. It is speculated that it may be related to the platform\u2010switching design and stability of the internal conical connection. Further clinical studies are warranted to assess the biomechanical reliability of eccentric abutments and the long\u2010term behavior of interimplant crestal bone when spacing is &lt;1\u2009mm.<\/jats:p>\n
