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, $Endopore^{(R)}$ 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 $Endopore^{(R)}$ 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 $Endopore^{(R)}$ 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 $3.26{\pm}1.04mm$.

상악 구치부 치조골의 해부학적 한계를 극복하기 위한 다양한 방법들이 시도되고 있다. OSFE법은 상악동거상을 위해 사용되어져 오고 있는 방법중 하나이며 본 연구에서는 Endopore 임플란트를 이용하여 상악동내에서 신생골의 형성을 관찰하였다. 66명의 환자에게 115개의 임플란트를 식립하고 평균 26.3개월동안 방사선학적 검사를 시행하였다. 4환자에게서 5개의 임플란트가 보철수복 후 제거되어 추적기간동안 95.6%의 생존율을 보였다. 상악동내에 형성된 신생골의 높이는 $3.26{\pm}1.04mm$이었다.
