“Skin substitutes should also be flexible and easily adjustable to the wound bed in order to provide “intimate contact” (without “dead spaces”)”

Importance of Overlap in Wound Coverage

When selecting a wound dressing, it is important to consider an overlap margin around the wound edges to ensure complete coverage and protection. An overlap of at least 0.5 cm is often recommended to account for wound contraction and movement, which can help prevent dressing displacement and reduce the risk of infection.
