[Biological glues and biomaterials in periodontal surgery. Description of a surgical reattachment technic].

Abstract

A major research problem over the past 10 years is to obtain a new attachment after treatment of roots previously exposed to periodontal disease. Among the most recent studies, two main objectives of surgery are suggested: a selection of cell population and to arrest epithelial migration by guided tissue regeneration with a membrane, and a biological and chemical root preparation with citric acid and fibronectin. A technique for the treatment of deep osseous lesion is put forward here: the association of biodegradable membrane--natural coral--citric acid and fibronectin.
