Abstract
The aim o f the present study was (i) to evaluate the gain and maintenance of new clinical attachment following GTR therapy of deep intrabony defects and (ii) to analyse the significant factors associated with the clinical outcome. Twenty-four defects in 19 patients were treated by GTR with ePTFE membranes. Clinical measurements were recorded at baseline and at 6 and 12 months post-surgically. GTR treatment resulted in a probing depth reduction (x = 3.8 ± 1.5 mm, p=.0001) and a gain clinical attachment (x = 2.6 ± 1.5 mm, p=.0001) after 6 months. The amount of probing attachment gain was explained in terms o f a series of patient, defect morphology and surgical factors. Clinical attachment gain was significantly associated with the intrabony depth of defect, the defect configuration, and the level o f oral hygiene.
