Radiographic evidence of bone regeneration using oxidized cellulose mesh as a bioabsorbable membrane: some case studies.

Abstract

Guided tissue regeneration has been described as a technique to enhance the regrowth of the periodontal tissues after surgical therapy. Originally, nondegradable materials were used for this purpose, but more recently, degradable materials have been advocated for this purpose. Utilizing an adapted technique in which the material was used as an infill material and barrier membrane, this small study in human subjects has demonstrated radiographically that the defects are filled with a bone-like material over a protracted period. Regeneration of tissues, with bone deposition in infrabony defects, may not be complete as long as 12 months after surgery.
