Treatment Outcomes of Implants Performed After Regenerative Treatment of Absorbed Alveolar Bone Due to the Severe Periodontal Disease and Endoscopic Surgery for Maxillary Sinus Lift Without Bone Grafts

ObjectiveWe have developed a regenerative medicine therapy for the alveolar bone and endoscopic surgery for maxillary sinus lift without bone grafts, in patients experiencing severe periodontal disease with significant absorption of the maxillary alveolar bone, in which more than 10 mm of bone thick
