BACKGROUND The aim of this randomized, controlled, prospective clinical study was to compare guided tissue regeneration (GTR) to enamel matrix derivative (EMD) for the treatment of intrabony defects in patients with chronic advanced periodontitis. METHODS Forty (39 evaluable) 3-wall intrabony defects, each with a depth > or = 4 mm measured from the crest of the bony defect, were treated in 40 subjects with advanced chronic periodontitis. Regeneration of angular bone defects was induced using… CONTINUE READING
