The present study suggests that comparable clinical, radiological, and aesthetic results can be achieved with all treatment protocols. Gingival recession, however, seems to occur in the long term irrespective of the technique used.

The results indicate that the maxillary sinus membrane, even in healthy clinical conditions, undergoes morphologic modifications after sinus floor elevation, yet membrane reactions demonstrate significant variability. Future research on the effect of augmentation surgery on maxillary sinus physiology is recommended.

Performing surgery before midday allows surgeons managing postoperative bleeding themselves for a better patient satisfaction. Intensified information about correct postoperative behavior is crucial. Prolonged blood coagulation should intensify follow-up checks. Patients with congenital blood disorders and patients at high risk for bleeding with the need for substitution of platelets or clotting factors should receive inpatient care. More potent, local applicable coagulant agents are required for these patients.

The hydraulic pressure and vibration technique allows a minimally invasive crestal sinus augmentation with a perforation rate less than 10% and implant survival rates of approximately 90%.
