Drill, elevate, inject, insert.
iRaise does not involve complex surgery, and can be performed by any dentist experienced in dental implant placement.. iRaise transforms what was once a highly specialized procedure that required prolonged chair time, into a quick and easy technique.
The iRaise is unique in that it enables the performing of crestal sinus augmentation, utilizing the special attributes of the implant to execute a safe hydraulic elevation procedure. This is achieved by injecting saline into the maxillary sinus through an internal channel in the implant. Hydraulic pressure is generated from the process, reducing the risk of perforating the Schneiderian membrane, which contributes to the procedure’s safety.
The procedure includes only four steps:
1. Drill an osteotomy in the sinus floor: A specialized drill sequence is used to safely reach below the Schneiderian membrane.
2. Elevate the Schneiderian membrane: Saline is injected through the implant and into the sinus. The hydraulic pressure generated by the saline gently detaches the sinus membrane from the sinus floor.
3. Inject bone graft: Bone graft in a gel formulation is injected through the implant.
4. Place implant: The iRaise implant is inserted entirely into the crest. After 6 to 9 months, when the bone graft has matured and osseo-integrated, rehabilitation procedure can begin, using standard techniques.
Hydraulic elevation of the Schneiderian membrane has been shown to exhibit <0.5% risk of perforation. See Chen, L. and J. Cha, J Periodontol, 2005. 76(3): p. 482-91.
