Evaluation of Clinical and Radiological Outcomes Following the Treatment of Periodontal Intraosseous Defects Using Autogenous Tooth-derived Graft or Autogenous Bone Graft With Enamel Matrix Derivatives. A 12-month Randomized Controlled Clinical Trial.

Participants receive periodontal regenerative surgery using autogenous bone graft harvested from a secondary intraoral donor site (mandibular ramus or maxillary tuberosity) with a bone scraper. The bone graft is placed into the debrided intraosseous defect, and enamel matrix derivative (EMD) is applied to the root surface. Surgical access is performed using a single flap approach (SFA), and primary closure is achieved with microsurgical sutures.

Participants receive periodontal regenerative surgery using autogenous tooth-derived particulate graft processed from an extracted tooth using a standardized protocol (Bonmaker® device and chemical decontamination), combined with enamel matrix derivative (EMD) applied to the root surface. The surgical site is accessed using a single flap approach (SFA), and graft material is placed into the non-self-contained intraosseous defect after debridement. Primary closure is achieved with microsurgical sutures.
