The objective of the present clinical study was to evaluate the efficacy of 4 membrans used for GTR treatment (Resolut Regenerative Material, Gore Tex Periodontal Material, Guidor, Vicryl). We defined "efficacy" by a reduction of the furcation defects, reduction of probing depth and attachment level.
As the results were very similar, we cannot recommend any particular of the 4 membrans used.
