Final answer:

Histologically detectable new blood vessels following a free gingival graft are generally visible by 2 to 3 days post-surgery. This phase is critical for the nourishment and integration of the graft with the recipient site.

Step-by-step explanation:

In the context of a free gingival graft, histological detection of infiltrating new blood vessels, indicative of revascularization, does not occur immediately. It is a critical part of the healing process as it ensures the supply of necessary nutrients and cells to the graft site. Unlike bone repair, where a fracture hematoma can form within six to eight hours following an injury, the detection of new blood vessels in a free gingival graft will take longer.

Typically, within the first 24 to 48 hours after the placement of the graft, the blood vessels in the graft begin to reestablish connections with the blood vessels in the recipient site during the initial healing phase. However, these new vessels will not be histologically detectable until a bit later. The infiltration of new blood vessels, which is part of neovascularization, is generally histologically detectable in a free gingival graft by 2 to 3 days after the surgery. By this time, early signs of the new blood vessel formation can be seen under microscopic examination. It is through these vessels that the graft starts getting integrated with the recipient bed and receives the nourishment it needs to survive and thrive.
