Estudio comparativo entre alloderm y mucograft como sustitutos de tejido conectivo para tratar recesiones gingivales.

Abstract

INTRODUCTION: Autologous connective tissue grafts are techniques with a good prognosis, however, an additional donor bed is needed. There has been talk of two allogeneic grafts and one xenograft, preventing the need for a second surgical intervention. OBJECTIVE: To establish the quality of graft types according to their characteristics as autologous connective tissue substitutes to treat patients with gingival recession. MATERIALS AND METHODS: Research with a qualitative approach, bibliographic type, descriptive and analytical design, deductive method based on the study of 30 articles about two types of graft. RESULTS: The indications are mainly to cover the exposed root and for aesthetics. Both matrices function as a scaffold for the growth of fibroblasts and endothelial cells that together produce a connective tissue matrix. They have an unlimited amount of tissue, reducing surgical time, morbidity and pain. The alloderm presents a root coverage range of 73.39%-100% and mucograft 71.21%-94.32%. The success of the graft depends on the percentage of colonization of the host cells in the graft. CONCLUSION: Although certain studies showed similar results to autologous grafting, they failed to match the periodontal parameters obtained with the Gold Standard, which is autologous connective tissue grafting.
