Characteristics
Obtained from derma of porcine origin, using an exclusive Tecnoss® process, Derma membranes are gradually integrated with the autologous soft tissues1. Their strong consistency and resistance allow a perfect stabilization and a prolonged protection of underlying graft in large regeneration procedures, together with a strong barrier action to guide the growth of epithelium and preventing its invagination.
Handling
Derma membrane can be shaped with scissors until the desired size is reached; then it must be hydrated for 5 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.
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.
Clinical indications
Derma membrane is a collagen resorbable barrier to protect and stabilize bone grafting materials; only in this specific indication it can be used also in open healing situations due to its perfect tissue integration characteristics. If a residual band of keratinized tissue is still present around teeth or implants, Derma membrane can be used as an alternative to connective tissue graft to improve the quality of keratinized tissues2.
Mild gingival recessions3 can be treated with Derma to avoid patient morbidity and discomfort due to connective tissue graft harvesting. It is recommended to leave Derma membrane completely covered by the coronally advanced flap and to avoid membrane exposure. A properly shaped Derma membrane with rounded edges is also indicated for the tunnel technique.
