ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the long-term clinical effect of dual anti-collagen membranes in guided tissue regeneration (GTR).</p><p><b>METHODS</b>This randomized clinical trial included 26 teeth in 24 patients, presenting a total of 31 lesions consisting of intrabony defects and furcation defects. Twenty-six teeth were divided into two groups and treated by GTR with dual anti-collagen membranes and atelocollagen membranes, respectively. At baseline, 6 months, 1, 3 and 6 years, the following parameters were recorded clinical attachment level, probing depth, gingival recession and the quantity of alveolar bone analyzed by computer assisted densitometry image analysis (CADIA).</p><p><b>RESULTS</b>At 1 year after GTR surgery, the gain of clinical attachment in dual anti-collagen membranes group was (3.93 ± 1.74) mm, compared with (2.25 ± 1.90) mm in atelocollagen group (P = 0.044). The increasing of the value of CADIA in dual anti-collagen membrane and atelocollagen group were (53.14 ± 21.35) and (32.96 ± 17.97), P = 0.031. At 3 and 6 years, clinical parameters remained basically stable in both groups, compared to that at 1 year after surgery.</p><p><b>CONCLUSIONS</b>The regeneration of periodontal tissues obtained by GTR with dual anti-collagen membranes could be maintained on a long-term basis.</p>
