Clinical and Histological Evaluation of Deproteinizated Bovine Bone Allograft and Lyophilized Equine Bone Allograft for Sinus Lift.

Clinical and Histological Evaluation of Demineralized Bone Allograft and Lyophilized Equine Bone Allograft for Sinus Lift: Double Blind, Parallel, Randomized Clinical Trial.

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.

Inclusion Criteria:

• bilateral atrophy of the maxilla;
• bone ridge <= 6mm

Exclusion Criteria:

• severe systemic diseas (ASA III -IV) bisphosphonate therapy or a history of up to 3 years history of radiation therapy to neck and head area sinusitis pregnancy subjects not able to consent to participate in the study.
