Use of soft tissue substitutes in periodontics and implant dentistry

Mucogingival surgery aims to correct those defects in the morphology, position and amount of soft tissues around teeth and or dental implants. The most frequent lesions are gingival or mucosal recessions and areas of lack of keratinized tissue that may compromise the stability of the gingiva or mucosa. To treat these lesions manysurgical techniques have been proposed mainly based on the use of autogenous soft tissue grafts or pediculated fl aps. In fact the gold standard in mucogingival surgery is the use of autografts, either connective tissue or gingival graft that require a second surgical procedure to retrieve the graft from the palate and are usually associated to higher or lesser degree of patient morbidity. In order to avoid the use of autografts and the harvesting surgical procedure, different soft tissue substitutes have been tested for effi cacy, mainly the use of allografts (dermal tissue substitutes). In the last years the use of xenogeneic soft tissue substitutes has been advocated. These xenografts are three-dimensional matrixes of porcine type I collagen. In this presentation we shall present the background research in the use of these materials, from their biological activity based in experimental research to their clinical effi cacy based on the results of clinical trials.
