When alveolar ridges lack the appropriate bone volume for implant placement, additional surgical procedures are necessary. In the posterior maxilla, the pneumatization of the maxillary sinus reduces the residual crestal height, and to perform implant placement, several sinus floor elevation techniques have been developed. These techniques involve specific instruments that require some experience, especially when performing sinus membrane lifting because of its importance for surgery success. A minimally invasive transalveolar sinus floor elevation technique is presented, in which a diamond burr used in cranial base surgery is employed. Surgery was performed on 10 patients. Panoramic radiographs and computerized tomography (CT) scans were taken before surgery and 1 month and 2 years after surgery, and they were used to measure bone height. The achieved augmentation heights were between 2.18 and 5.93 mm. All of the surgical procedures were conducted without complications. No Schneiderian membrane was perforated, and a vertical augmentation for allowing implant placement was achieved. It represent a good technique for minimally invasive sinus floor elevation.
