Abstract
Purpose: The purpose of this article is to evaluate a change o bone level on the sinus floor by a bone added osteotome sinus floor elevation (BAOSFE) technique, according to the amount of deproteinized bovine bone mineral (DBBM). And Changes in augmented bone height after BAOSFE procedure were also assessed for 6 months after the implant procedure.
Materials and Methods: Forty eight single implants were placed in the posterior maxilla using BAOSFE technique. The
implantation sites were classified into two groups according to the amount of grafted DBBM, 0.25 group (0.25g) and 0.5 group (0.5 g). Panoramic views or cone-beam computed tomography (CBCT) were taken at the time of implant placement with BAOSFE and after at least 6 months to assess the bone level changes in the elevated sites with DBBM.
Results: Alveolar bone level around all implants was stable clinically and radiographically during the follow-up. Mean
augmented bone height was 5.21 0.94 mm in 0.25 group and 6.92 1.19 mm in 0.5 group. Statistically significant difference in
augmented bone height was found in the comparison between the 0.25 group and 0.5 group at the time of surgery. There was a positive correlation between the length of the implant protruding into the maxillary sinus and the augmented bone height. After 6 months, mean reduction of augmented bone height was 0.50 0.34 mm in 0.25 group and 0.41 0.30 mm in 0.5group. There was no specific correlation between the reduction of augmented bone height and amount of grafted DBBM.
Conclusion: Within the limit of this study, the amount of grafting materials and the protrusion length of implant into the
maxillary sinus affect the amount of the augmented bone height.
