Correct answer: A3 mm

The minimum recommended distance between two adjacent dental implants is 3 mm (center-to-center, depending on implant diameter). This allows adequate bone volume between the implants for crestal bone maintenance and soft tissue health. Placing implants too close (<3 mm) can result in interimplant crestal bone loss, compromised blood supply, and loss of the interdental papilla. The minimum implant-to-tooth distance is 1.5-2 mm.
