[Periodontal reconstruction using the guided tissue regeneration technique. Apropos of a case]

Different surgical techniques have been used to treat periodontal osseous defects. Periodontists were very full of hope with osseous grafts but the results were disappointing or unpredictable. A best knowledge of the biologics determinants of periodontal healing has lead to the concept of guided regeneration. A case of deep osseous defect of a mandibular incisor was treated by the placement of a Gore Tex membrane. The clinical and radiographic result is satisfactory.
