Abstract
- We performed sinus bone graft using some amount of autogenous bone and BioOss(R) and covered the sinus window with Ossix(R) membrane in these case series. After 4 to 6 months after operation, histopathologic examinations of trephine core biopsy showed following results. 1. There were bone density of 39.2 percent to 41.2 percent four months after operation, and we could observe the favorable early new bone formation. 2. Active bony remodeling of woven and lamellar bone was observed during 4 to 6 months healing period. 3. There were no significant differences between two groups. And also there were no significant differences between 4 months and 6 months.
