Abstract

---

In view of situations in which bone remodeling causes a large pneumatization of the maxillary sinus, the use of alternative techniques is necessary to optimize atrophic maxillary rehabilitations. Our proposal suggests the use of long implants by transferring the maxillary sinus when there is no remaining volume of bone in the posterior region of edentulous jaws. Two anterior implants are performed followed by two more implants of 22mm length, transfixing the maxillary sinus which will also be filled with heterogenous graft. Long implants allowed for apical anchoring in the nose wing, allowing sufficient primary locking for immediate loading and positioning of the prosthetic platform in the first molar region, eliminating the cantlever extension of the prosthesis and consequently improving the biomechanics of the system. In this way, we were able to rehabilitate patients with severe resorption of maxilla, in a simple, fast and safe way. Longitudinal studies become necessary to validate the technique.
