ARDILA MEDINA, C.M.. Biomechanical properties and sterilization process of allodermics matrix used on periodontic. Avances en Periodoncia [online]. 2011, vol.23, n.3, pp.187-193. ISSN 2340-3209.

Several surgical procedures have been proposed for the preservation and increase of the alveolar ridge, and for the treatment of gingival recessions and to increase the width of attached gingiva around natural teeth or implants. The disadvantages of harvesting autogenous grafts on these procedures lie in the postoperative discomfort associated with an extra surgical site, as well as the limitation of available donor tissue. Recently, two types of acellular dermal matrix allografts have been approved as substitutes for autogenous grafts in mucogingival surgery. Due to the increased use of allografts on periodontics and other areas of health sciences, has brought more focus to the safety of allogenic tissue and the efficacy of various sterilization techniques. Unfortunately, these sterilization techniques could produce deleterious effects on the biomechanical properties of allogenic tissues, causing undesirable results on the interventions. Moreover, it has been suggested that despite the thoroughness of the evaluation processes and tissue donors, in addition to the processing of the matrices, there is possibility of retention of genetic material on allografts commercially available
