Before the introduction of the iRaise sinus lift implant, the sinus lift elevation was a highly invasive surgical procedure. While the specific technique varies among clinicians, traditionally it is performed by making an incision in the patient's gum tissue and exposing the jawbone. The exposed bone is cut to create an opening. Through this opening, the dentist accesses the delicate membrane that lines the inside of the sinus, and separates it from the sinus floor. The empty space underneath the lifted sinus membrane is then packed with bone-graft material where the implant will be placed in a subsequent procedure.
This surgical procedure requires sedation. The recovery time is approximately two weeks. There is significant pain and swelling. Patients usually stay at home for several days after surgery. And the risks of post-operative complications and recurrent sinus infections remain a challenge.
The iRaise sinus lift procedure requires no sedation. It is a one-step procedure and requires no downtime. Pain and swelling are minimal.
The iRaise sinus lift implant is uniquely designed to allow the introduction of fluid into the maxillary sinus through the implant body. The iRaise implant is placed in the upper jaw bone and the tip is inserted through the sinus floor. Saline is injected through the special channel into the sinus. The hydraulic force generated by the saline gently lifts it and creates a cavity below the membrane. The saline is then drained from the sinus. Bone graft is injected through the internal channel, and the implant is fully seated. The area is then sutured.
When the bone graft has matured and osseointegration of the implant into the bone is complete after approximately six to nine months, the prosthetic tooth is placed on the implant.
