The iRaise system allows the clinician to perform a minimally invasive sinus augmentation procedure immediately. The hy- draulic elevation of the Schneiderian membrane and the insertion of bone graft material are per- formed through the implant itself, resulting in fewercomplications, shortertreatmenttime and greater comfort for patients, compared with the open sinus lift procedure. Closed major sinus floor augmentation with a transcrestal approach can be accomplished using a novel system that allows for hydraulic elevation ofthe Schneiderian membrane, injec- tion of a flowable bone graft material and simultaneous dental implant placement, with minimal patient discomfort. Long-term clinical studies on larger cohorts of patients are needed to confirm these preliminary results. Competing interests This was an investigator-initiated trial. The trial was supported partially by Maxillent. Acknowledgments The authors wish to thank Maxillent (Herzliya, Israel) for its partial support of this trial and provision of the implants and prosthetic com- ponents. The authors also wish to thank the staff of the dental laboratory (Odontotecnica Paglia & Moretti, Rome, Italy) who manufac- tured the definitive prostheses.
