TBackground: In cases of advanced maxillary sinus atrophy of the bone, the sinus floor has to be augmented in order to obtain acceptable bone volume for dental implantation. This presentation will review the sinus lift techniques in current clinical practice. It will also present a new procedure and device, designed as a closed sinus lift based on a dedicated dental implant: the iRaise™ Sinus Lift Implant. A clinical study examining the safety and efficacy of the Sinus Lift Implant will be reviewed.

Materials and Methods: Eighteen patients (8 males, 10 females) underwent 23 procedures. All procedures were completed successfully, with elevation of the sinus membrane and insertion of bone graft and the dental implant at the planned site. No membrane tears occurred. No intraoperative or postoperative adverse events were observed in any of the cases. Patients needed very little medical attention: no patient required additional pain control medication or medication for swelling alleviation. There were no post-procedural emergency or distress calls.

Results: Average age-52; residual alveolar ridge height-5.5 mm; bone gain 10.9 mm; average waiting time until exposure-8.4 months. All cases exhibited significant generation of new bone at the sinus floor. All the implants achieved clinical osseointegration. All exposed implants exhibited excellent clinical stability in the jawbone. Prosthetic rehabilitation proceeded uneventfully.

Conclusions: iRaise™ appears to be a safe and effective way to execute a sinus floor augmentation procedure.
