Correct answer: B — 2 mm
While the absolute minimum width of keratinised mucosa (KM) around dental implants for long-term health is debated, a minimum of 2 mm of KM is generally recommended. Studies show that inadequate KM around implants is associated with increased plaque accumulation, mucosal inflammation, attachment loss, and mucosal recession. Sites with <2 mm KM may benefit from soft tissue grafting (free gingival graft or xenogeneic collagen matrix) at or after implant placement.
