Can a Skin-Derived graft match the gold standard for saving molars?

This trial tests two surgical techniques for repairing furcation defects—areas where bone loss has occurred between the roots of lower molars—in people with advanced periodontitis. One method uses a graft derived from donated skin (acellular dermal matrix), while the other uses a connective tissue graft taken from the patient's own palate. Both are combined with enamel matrix derivative and bone graft material. The study also checks how accurately 3D imaging (CBCT) measures these defects compared to direct measurements during surgery. The goal is to see which approach better reduces pocket depth and improves attachment levels, potentially offering a less invasive option for saving teeth.
