In the last decades, Guided Tissue Regeneration techniques (GTR) have been applied in treating vari- ous periodontal defects such as infrabony defects, furcation involvement and localized gingival recession defects and it has been suggested that clinical signs of probing attachment gain and bone fill can be accepted as evidence of periodontal regeneration in the evalua- tion of GTR procedures.13,14,15,16
