Brief Summary

This multicenter randomized controlled clinical trial aims to compare the clinical, radiographic, microbiological and molecular outcomes of two collagenated xenogeneic bone substitutes (GTO® and GenOs®) used in combination with the Non-Incised Papilla Surgical Approach (NIPSA) for the treatment of intrabony periodontal defects. The study will evaluate whether differences exist between the two biomaterials with respect to clinical attachment gain, defect resolution, wound healing and biological markers of regeneration.
