Abstract
Few studies exist which document the use of resorbable membranes in humans. The aim of the present study was to evaluate the results of treatment with a membrane based in a lactic and glycolic acids copolymer (Resolut®) in furcation lesions and intrabony defects in eight patients followed up over 1 year. Patients and Methods: 4 class two furcation lesions and 4 interproximal defects were selected. Prior to surgery probing depth, gingival recession (clinical attachment level), plaque and gingival index, the presence of bleeding on probing and mobility were measured. lntraoral radiographs were also made. After the elevation of a full thickness flap, defects were debrided and measured, a carefull instrumentation of the exposed root was carried out, and the membrane was placed at the nearest possible level to the cementum-enamel junction, and sutured to the tooth with Dexon®. The flap was repositioned with the intention of cove- ring the membrane and was sutured with teflon (Gore-Tex®). The sutures were removed at four weeks. A clinical follow-up was made at 1, 2, 4, 6, 8 weeks and 3, 6 and 12 months, and radiographs were made at 6 at 12 months. Results: Both groups demonstrated an important gain in clinical attachment level at twelve months. In the intrabony deffects the gain was 5.3 (1.1)mm, while in the furcation lesions the gain in vertical attachment level was 3.3 (0.5)mm, and the horizontal gain was 4.0 (0.8)mm.
