  Purpose

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.


Condition Intervention
Sinus Graft Device: bovine bone mineral particles (Bio-Oss®)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
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

Arms Assigned Interventions
Active Comparator: 1
small particles
Device: bovine bone mineral particles (Bio-Oss®)
bovine bone mineral particles used for sinus augmentation prior to dental implant placement
Other Names:
  • bovine bone mineral particles (Bio-Oss®) small particles
  • bovine bone mineral particles (Bio-Oss®) large particles
Active Comparator: 2
large particles
Device: bovine bone mineral particles (Bio-Oss®)
bovine bone mineral particles used for sinus augmentation prior to dental implant placement
Other Names:
  • bovine bone mineral particles (Bio-Oss®) small particles
  • bovine bone mineral particles (Bio-Oss®) large particles

Detailed Description:

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.
