What is the recommended minimum distance between two adjacent dental implants?

The recommended minimum distance between two adjacent dental implants is 3 mm (center-to-center distance of the implant platforms minus the implant diameters). This spacing is necessary to preserve the interimplant bone (crestal bone between implants), allow for proper osseointegration, maintain adequate blood supply to the interimplant bone, and accommodate papilla formation for esthetics. Inadequate spacing leads to crestal bone loss between implants, which can compromise long-term implant survival and esthetics.
