Introduction: Anorganic bovine bone (Bio-Oss®) has been extensively used for reconstruction of posterior area of
maxilla in sinus lift procedure; howev)e use of dental implants for oral rehabilitation of partial or
total edentulous patients has become a promising therapeutic modality in recent decades, returning to patients the
functions of the stomatognathic system by masticatory
restoration and aesthetics [1, 2].
After teeth loss, a physiological process takes place which
leads to bone resorption of the alveolar ridge in thickness
and height, becoming a limiting factor for the placement of
dental implants, without prior reconstruction of the region
with bone grafts [1, 2].
Autogenous bone graft is still considered to be the “gold
standard” because it has osteogenic, osteoinductive, and

osteoconductive properties [1–3]. To overcome the disadvantages of autogenous bone removal in performing bone
reconstruction, new materials are being developed in order
to assist bone repair in regions where the intention is to
maintain or restore bone volume [4]. )ese biomaterials are
designed to maintain the three-dimensional framework in
the region to be repaired and develop an osteoconductive
surface structure leading to migration of osteoblasts and
deposition of bone matrix [5]. Although bone substitutes
have the same purpose of dimensional maintenance and
osteoconductive surface, the quality of bone formation may
differ in physicochemical characteristics depending on the
bone substitute applied. It is possible to argue, then, that the
manufacturing method is responsible for the properties

conferred on the biomaterial, and therefore, its ability to
interact with the native bone [6].
