In cases after flap reflection, it should be slightly and minimally released.
The release cut should be at the base of the flap and minimal as possible, so during the closure itself, the flap should be placed directly above the graft without using any membrane while there should be maximal closure with moderate tension. (shouldn’t be tension free as we are used to with granules and membranes).
It will provide less pain to the patient, less swallowing, stability to the graft during healing and higher predictability.
Exposure of maximum 1-3mm is not an issue. The soft tissue will proliferate rapidly above the cement and bridge the gap. Do not leave it exposed more than this as you may lose volume.
