Abstract
Background: A study is made to evaluate the clinical efficacy, in terms of clinical attachment gained, of two resorbable membranes versus a positive control (non-resorbable membrane), in the treatment of two-three wall intrabony defects. Patients and method: We selected 36 patients in whom 43 two-three wall intrabony lesions were detected. Prior to surgery we recorded pocket depth and gingival recession (clinical attachment level). 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 weeks, and 3, 6 and 12 months, with radiological controls after 6 and 12 months. Results: A total of 36 defects completed the study, corresponding to 30 patients. After one year a mean reduction in pocket depth of 3.98 mm was recorded, with a 0.17 mm recession increment and a clinical attachment gain (NCI) of 3.97 mm. No significant differences were observed between the different membranes used.
