Regenación periodontal en defectos de furcación de grado II con tres membranas diferentes. Un ensayo clínico aleatorizado

Abstract

Background: The present study was designed to evaluate the clinical efficacy, in terms of clinical attachment gain, of two reabsorbable membranes versus a positive control (non-reabsorbable membrane), in the treatment of class II furcation defects. Patients and methods: Sixteen patients were selected, in whom 19 class II furcation lesions were detected. Prior to surgery, pocket depth and gingival recession (clinical attachment level) were recorded. After a full thickness flap approach, debridement and measurement of the defects, and instrumentation of the root wall, the membrane was placed. Clinical follow-up was carried out after 1, 2, 4, 6 and 8 week , and 3, 6 and 12 months, with radiological controls after 6 and 12 months. Results: A total of 18 defects completed the study, corresponding to 15 patients. After 1 year, a mean reduction in pocket depth of 2,55 mm was recorded, with a 0,33 mm increase in recession and a clinical attachment gain of 4,33 mm. Conclusion: No significant differences were observed between the different membranes used.
