There are many clinical presentations for which soft tissue grafting procedures are the treatment of choice. Some of these indications are: gingival recession, lack of keratinized tissue around teeth or implants with symptoms or difficulties performing oral hygiene and other acquire or developmental mucogingival defects.

There are several options for soft tissue grafting: autograft, allografts and xenograft. Autograft refers to tissue taken from the same patient, mostly from the palate, and transplanted to the site with the defect. Allograft refers to tissue donated from another human. There are several commercially available products: Alloderm and Puros Dermis Allograft Tissue Matrix. Xenograft is tissue obtained from a different species. At this time, Mucograft is the only xenograft commercially available and it is from porcine origin.

Autograft is still considering the goal standard and offers the advantage of eliminating risk of disease transition and has excellent long-term predictability. Allograft and xenograft offer the advantage of eliminating the need for a second site surgery but precautions are necessary since several contraindications exist for example allergies to gentimicin, cefoitin, lincomcin, Polymixin B, Vancmycin and polysorbate 20.

To decide which of these options are viable for a specific case, consult with your periodontist as the viability depends on the specific clinical presentation, goal of the procedure, patient’s medical history and patient’s preference.
