Socket Preservation Using a Biomimetic Nanostructured Matrix and Atraumatic Surgical Extraction Technique.

Objective: The aim of the present study was to evaluate the efficacy of biomimetic composite bone substitute composed of equine collagen I and Mg-hydroxyapatite in improving socket preservation after tooth extraction in humans. Methods: Thirty-two patients were subjected to a single tooth extraction, performed without elevation of the full-thickness flap. In each patient, socket was grafted with the bone substitute and specimens were retrieved 2 months after surgery and processed for histological observations. The clinical outcome variables were healing index, visual analog score for pain, postsurgery complications, and patient satisfaction evaluated through a questionnaire. Results: No adverse reaction or infection occurred, in which healing index averaged 5.8 (range 4-7). Pain scores were lower. The patients' questionnaire outcomes were unanimously in favor of the test treatment. At low-power magnification, it was possible to see a portion of native bone with small marrow spaces and many areas of bone remodeling. At high-power magnification, it could be observed that small newly formed trabeculae originated from the preexisting bone and bone spicules in the middle of the defect. Conclusion: Grafting the postextraction socket with composite bone substitute may improve the healing process by accelerating socket closure and tissue maturation. Such a product demonstrated excellent biocompatibility as no inflammatory reaction could be detected histologically and was well accepted by patients. (C) 2017 by Mutaz B. Habal, MD.
