Derma

Characteristics
Obtained from derma of porcine origin, using an exclusive Tecnoss® process that preserves the natural collagen fibers, Derma membranes are gradually integrated with the autologous soft tissues. Their strong consistency and resistance allow a perfect stabilization and a prolonged protection of underlying graft in socket 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 thoroughly hydrated in sterile lukewarm physiological solution until the desired consistency is obtained. 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.

Clinical information
Derma membrane is a collagen resorbable matrix useful to augment soft tissues and 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 tissues. Derma has been also documented for horizontal soft tissue augmentation around implants.
Mild gingival recessions can be treated with Derma to avoid patient morbidity and discomfort due to connective tissue graft harvesting. To avoid membrane exposure, usually Derma is completely covered by the coronally advanced flap. A properly shaped Derma membrane with rounded edges has been also documented for the tunnel technique.
