The technique combined tetracycline treatment of a root planed root, grafting of the osseous defect with a demineralized freezedried bone allograft combined with tetracycline and the placement of a bioabsorbable matrix membrane, made of polylactic acid softened with citric acid ester. Thirty defects were treated in 27 patients. Statistically significant changes, as a result of the surgical procedure, were observed in marginal recession (mean: 0.5 mm), probing depth reductions (mean: 5.7 mm), and attachment level gain (mean: 5.2 mm). No statistically significant difference existed between the results in the furcation and non\u2010furcation groups. The defects with probing depths \u2265 10 mm had a greater mean probing depth reduction (7.4 mm) and mean attachment level improvement (7.2 mm) than the defects with &lt; 10 mm probing depths (probing depth reduction 4.5 mm and attachment level gain 3.9 mm). The proposed surgical procedure seemed to be an effective method to treat periodontal defects. <jats:italic>J Periodontol 1997;68:598\u2013607<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.1997.68.6.598","type":"journal-article","created":{"date-parts":[[2012,3,20]],"date-time":"2012-03-20T18:20:37Z","timestamp":1332267637000},"page":"598-607","source":"Crossref","is-referenced-by-count":8,"title":["A Clinical Evaluation of Guided Tissue Regeneration With a Bioabsorbable Matrix Membrane Combined With an Allograft Bone Graft.
