Sinus bone graft using combination of autogenous bone and BioOss.: comparison of healing according to the ratio of autogenous bone

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.N

Guided bone regeneration using Regenaform. and Ossix. membrane: three case reports

This case study investigated the clinical effect of guided bone regeneration (GBR) using Regenaform. and Ossix. membrane and the histology of the new bone that formed just under the membranes. Regenaform. transplantation and covering with Ossix. membrane were performed to repair bone defects around implants after implantation in three patients. After 3~4 months, the membranes were removed in a second operation, and a biopsy was taken under the membrane. The biopsies showed a bone density of 23~42%, and subsequent prosthetic treatments were successful in all cases.N
