Derma membrane can be shaped with scissors until the desired size is reached; then it must be hydrated for 15 minutes in sterile lukewarm physiological solution.
Once it acquires the desired plasticity, it must be adapted to the grafting site. It is always recommendable to prepare a pocket with an elevator in order to stabilize the membrane in the site after stitching the flaps. If this is not possible, the membrane can be stitched with envelope sutures which bridle it with the gingival flaps.
N.B.: if Derma membrane, for any reason, shows dehiscences (for example in the secondary tearing of flaps) it must absolutely not be removed, because its plasticity and consistency is such as to allow it to achieve a complete second intention healing of the wound, because of the physiological sliding of the flaps.
