발치후상악동이 함기화 되면서 임프란트를 식립하기에 부족한 골양을 보이는 경우가 많다. 이 문제를 해결하기 위해 Tatum은 치조능을 통한 상악 동저 거상과 submerged implant 식립을 주장한 최초의 임상가였으며1) 1980년대 Boyne과 James는 자가골을 이용하여 상악동의 sub-antral filling의 외과적 기법을 한 층 더 발전시키면서 최초로 논문을 발표하였다2).
Introduction. This study was intended to determine the survival rate of implants placed in grafted maxillary sinuses and compare the results obtained with timing of implant placement under 4mm residual bone height Materials and Methods. I retrospectively reviewed the medical records of 52 cases of implants from 24 patients, who were treated at gong-dan dental clinic from April 2006. Simultaneous implant placement after sinus bone graft were 40 cases, and number of delayed protocol were 14 cases Result. The survival rate of simultaneous protocol group was 95% and the survival rate of delayed protocol was 100% Conclusion. It is considered that the clinical outcome of sinus bone graft and simultaneous implant placement is similar to the delayed placement. So, simultaneous implantation is recommended if primary stability is obtained although under 4mm residual bone height. [THE JOURNAL OF THE KOREAN ACADEMY OF IMPLANT DENTISTRY 2011;30(1):71-76]
