Efficacy of Sinus Floor Augmentation Using Large or Small Bovine Bone Mineral.
Recruitment status was Not yet recruiting
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.
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.

|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 relative amount of mineralised tissue (=newly formed bone plus BO)
- Relative amount of newly formed bone, graft residues, bone marrow, residual bone and connective tissue.
- Clinical parameters:
- complications during surgery related to the material.
- post-operative complications.
- Max torque for implant insertion.
- short-term implant survival (up to one year post loading)
|Study Start Date:||March 2007|
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.
