Aim of the study: To investigate alveolar socket preservation with two different particle sizes of demineralized bovine bone mineral (DBBM) small-sized particles (0.25–1 mm) and large-sized particles (1–2 mm) by means of histological, clinical and radiograhic analysis.
Materials and methods: Clinical parameters included; vertical bone height and bone width that were recorded at baseline and at three months after extraction. Moreover, histomorphometric parameters included; area fraction of newly formed bone three months after extraction by histomorphometric analysis. Radiographic parameters included superimposition of baseline CBCT and another one done three months after extraction with subsequent measurement of bone height, bone width and bone density. A core biopsy was taken three months after tooth extraction which has undergone histomorphometric analysis; implant placement was also done at the same time.
Results: The histomorphometric analysis showed a significant difference between different groups. The highest value was found in the large particles group, followed by the small particles group while the lowest value was found in the control group.
Conclusion: Xenogenic bone graft Particle size has no effect on the quality of newly formed tissue after 3 months of alveolar ridge preservation.
