측방 접근법에 의한 상악동 거상술을 이용하여 식립된 골내 임플란트의 10년간 후향적 연구 = Long-term evaluation of implant placed in sites grafed by lateral window approach on maxillary sinus;a 10-year retrospective study

다국어 초록 (Multilingual Abstract)

Between 1997 May and 2007 May, One hundred and seventeen patients were treated. There were 129 cases of sinus elevation using a lateral window opening procedure and 258 implants placed simultaneously or delayed. The cumulative survival rate of the implants calculated. The implants were evaluated according to surgical site, quality and quantity of bone, graft material, membrane used, the length and diameter of the implant and complications. 1. The 10-year cumulative survival rate of the implants by sinus augmentation using lateral window approach was 96.90%. 2. There was no difference in the survival rate between the implant placed simultaneously with sinus elevation (one stage) and the procedure performed in the delayed procedure (two stage). 3. There was no difference in the survival rate according to the type and amount of graft materials. 4. There was no difference in the survival rate according to the implant site, bone quality and quantity. 5. There was no difference in the survival rate when the $CollaTape^{(R)}$ or Gore-Tex was placed in the window of the lateral wall. 6. There was no difference in the survival rate of the implant length and diameter. 7. The survival rate was as low as 75.00% when there were more than two complications. Implant placement with sinus augmentation using the lateral window approach is a predictable treatment method. Although the vertical height of residual ridge is insufficient and the quality of bone is poor, the normal survival rate of the implants would be expected if an appropriate graft material and membrane is used with greater effort to prevent complications.
