Maxillary Sinus Floor Augmentation

Brief summary
The sinus infiltration technique for sinus floor elevation has been used successfully when a reduced vertical height is available in the posterior maxilla. However, the effect of the different graft material on the volume and on the quality of new bone formed has not been fully investigated. The aim of this study is to evaluate the clinical and histological effect of a test material, lyophilized equine bone (Bio-gen®), compared with control material, deproteinized bovine bone (Endobon®), in the sinus lift techniques with lateral approach.

Outcome results
Histomorphometric Evaluation of New Bone Formation.
Time frame: 6 months
Population: Caucasion patients aged ≥ 25 years with at least one atrophic posterior maxilla (distally from first bicuspid teeth) with a residual crest height ≤4 mm who need sinus lift augmentation for dental implant placement were eligible for the study.
