What is the ideal thickness of a Free Gingival Graft (FGG)?

  1. 0.5-1mm

  2. 1-1.5mm

  3. 1.5-2mm

  4. 2-2.5mm

The correct answer is: 1-1.5mm

The ideal thickness of a Free Gingival Graft (FGG) is typically between 1-1.5mm. This thickness range is important to ensure that the graft is robust enough to withstand the healing process and provide adequate tissue thickness after integration. A thickness below this range may not provide sufficient tissue volume for successful grafting, while a thickness above this range may lead to increased complications during the healing phase. Therefore, maintaining a thickness of 1-1.5mm is considered optimal for successful outcomes.
