Sinus Graft Clinical Trial
Official title:
Efficacy of Sinus Floor Augmentation Using Large (1-2mm) or Small (0.25-1mm) Bovine Bone Mineral Particles (Bio-Oss®): A Comparative Histomorphometric Clinical Study
The aim of this clinical study is to compare the amount of newly formed bone after bone
augmentation with Bio-Oss® (BO) 0.25-1 mm vs. Bio-Oss® (BO) 1-2 mm in the sinus floor
augmentation procedure bilaterally in 8 patients.
Hypothesis:
There is no difference in the relative amount of newly formed bone plus BO between the large
(1-2 mm) and small (0.25 - 1 mm) granules.
the use of bovine bone mineral particles (Bio-Oss®)in sinus floor augmentation is well
established. bovine bone mineral is an oseoconductive material which serves as a space
maintainer and a scaffold for bone augmentation. the commercial product is manufactured in
two different particles sizes, "large"1-2 mm, and "small"0.25-1 mm.
Comparison: the histologic characteristics of augmented bone after the use of Bio-Oss® (BO)
with particle size of 0.25-1 mm vs. Bio-Oss® (BO)with particle size of 1-2 mm.
