Endoscopic maxillary sinus lift without vestibular mucosal incision or bone graft.

Aim: To augment the thickness of the maxilla in cases with marked absorption of the alveolar bone of the upper jaw due to severe periodontal disease by performing a minimally invasive sinus lift procedure without an iliac bone graft.

Methods: An endoscope is inserted into the nasal cavity, and a large drainage opening is created in the inferior meatus extending from the maxillary sinus to the nasal cavity. The endoscope and forceps for mucosal removal are then inserted into the maxillary sinus via the drainage opening, and approximately, the lower half of the maxillary sinus mucosa is excised.

New regenerative treatment for tooth and periodontal bone defect associated with posttraumatic alveolar bone crush fracture.

We developed a new regenerative treatment of tooth and periodontal defect and tooth dislocation associated with posttraumatic alveolar bone crush fracture in the region of the maxillary anterior teeth. Using this method, dislocated teeth are first extracted and crushed alveolar bone is debrided. The dislocated teeth are then reimplanted, and cancellous iliac bone (bone marrow) is grafted to the area surrounding the teeth to regenerate periodontal bone.
