Abstract

Aim: The aim of this study was to compare between different particle sizes of Geistlich BioOss bone graft material in sinus floor augmentation procedure in terms of bone height gain and histological analysis of a bone core biopsy obtained during the second stage surgery of implant placement.
Materials and Methods: Ten patients (seven males and three females with a mean age of 54.4 ± 6.9 years) with bilaterally deficient maxillary posterior bone height (3-4 mm) and seeking the placement of dental implants were included in this study.
A split mouth technique for the ten patients with a total number of twenty sinus lifting procedures were carried out and divided equally into two groups. One side was randomly assigned to be augmented with large bio-oss particles (Group A) and the contra-lateral side was augmented with small bio-oss particles (Group B). Both groups were evaluated radiographically and histologically after 3 months postoperatively.
Results: There was a non-statistically significant difference between large and small bio-oss bone granules concerning bone height gain and histomorphometric analysis.
Conclusion: Our results showed a non-statistically significant difference radiographically and histologically between large and small BBM (Bio-Oss) granules in sinus floor augmentation. Both sizes demonstrated excellent results in sinus floor augmentation procedures in terms of osteoconductive potential and adequate vertical bone height gain required for placement
of dental implants.
