Crestal sinus lift using iRasie implant
Lateral sinus lift
Device: iRaise Sinus Lift implant (Maxillent, Herzliya, Israel). Procedure: crestal sinus lift augmentation. We tested crestal versus lateral approach to the sinus. Crestal approach is made by a novel device (iRaise, implant system). Lateral approach is made conventionally with gold standard procedure (lateral approach). The iRaise Sinus Lift implant is made of Titanium-6 Aluminum-4 Vanadium alloy, have a surface treated with grit blasting using an apatitic calcium phosphate media, followed by acid etching, and have an internal hexagon connection. Implants have an internal l-shape channel to allow saline and graft passage. This implants system is made to perform crestal sinus lift procedure at the same time of the implant placement using the same device. After implant site preparation and initial implant placement, the hydraulic system is connected to the implant to allow the injection of saline and then graft the material. Then, the implant, is inserted for its full length.
Conventional procedure. Lateral approach to the sinus was made following the conventional procedure. A window on the lateral wall of the sinus is performed according to a conventional surgical lateral approach to the sinus cavity. Graft materials is filled inside the sinus cavity. Finally, iSure implants [Maxillent] are placed, and flap is sutured.
