Many surgical techniques have been utilized to restore gingival tissue dimensions including the use of autologous soft tissue graft. Longitudinal studies have shown that procedures using pedicle and free grafts are both effective for this purpose. However, since this technique uses epithelialized grafts, it generally results in compromised aesthetics ("patch-like area"). Alternatively free connective tissue grafts (CTG) are used providing similar predictability but resulting in better colour matching. Unfortunately, both techniques are associated with significant patient morbidity due to the wound at the palatal donor site. To avoid patient morbidity, acellular dermal allografts have been used as substitutes for palatal donor tissue, demonstrating the possible and promising use of allograft material. However, since the allograft material is derived from human cadavers; it is associated with ethical concerns and the risk of disease transmission.
