Abstract
|
|
|
|
Various techniques and diversely designed implants have been developed to overcome anatomic limitations of the maxillary posterior alveolar bone. The OSFE (osteotome sinus floor elevation) technique has been used for maxillary sinus augmentation. Also, Endoporeⓡ implant was designed to increase the surface area by its sintered porous surface. The purpose of this study was to evaluate the survival rate of Endoporeⓡ implants placed in the posterior maxilla in association with the elevation of the sinus membrane using OSFE technique, and examine the new bone formation in the sinus. One hundred fifteen Endoporeⓡ implants in 66 patients were placed in the posterior maxilla by OSFE technique. The implants were clinically and radiographically followed up for an average of 26.3 months. Most implants were stable and radiographs showed that the bone regenerated in contact with the implants. But, 5 implants in 4 patients were removed after the prosthetic restoration and the survival rate was 95.6% during the follow-up period. The height of new bone formed in the sinus was 3.26±1.04mm.
