Sinus Floor Elevation Using Alpha-Bio's GRAFT Natural Bovine Bone vs. Commercially Available Bone Graft
This trial is active, not recruiting.
|Condition||sinus floor augmentation|
|Treatments||alpha-bio graft natural bovine bone, natural bone substitute|
|Sponsor||Alpha - Bio Tec Ltd.|
|Start date||May 2014|
|End date||December 2016|
|Trial size||44 participants|
|Trial identifier||NCT02384291, ABT-BG-01|
This clinical study is designed to compare the regenerative outcome of using separately two different Xenografts during sinus floor augmentation.
Aim of this prospective randomized-controlled clinical trial is to compare the regenerative results of Alpha-Bio's GRAFT Natural Bovine Bone versus commercially available bone graft after two-step sinus floor elevations by clinical and histological analysis.
Clinical Parameters are wound healing parameters, radiological volume stability and implant survival rates. Histological parameters are based on a histomorphometrical analysis of trephine cores harvested in progress of implant bed preparation.
|Endpoint classification||bio-equivalence study|
|Intervention model||parallel assignment|
|Masking||single blind (subject)|
