|
|
We performed sinus bone graft using some amount of autogenous bone and BioOss and covered the sinus window with Ossix 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% to 41.2% 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.
