BACKGROUND Xenografts to augment the maxillary sinus have been used extensively. The aim of the present study was to evaluate, qualitatively and quantitatively, two different HA derivatives of natural and synthetic sources on newly formed bone in the augmented sinus. METHODS A bilateral sinus augmentation procedure with simultaneous (16 out of 20 sites) or subsequent implant placement was per...

PURPOSE The aim of this study is to determine whether certain biomaterials have the potential to support cell attachment. After seeding bone marrow stromal cells onto the biomaterials, we investigated their responses to each material in vitro. METHODS Rat bone marrow derived stromal cells were used. The biomaterials were deproteinized bovine bone mineral (DBBM), DBBM coated with fibronectin (...

The purpose of the present case report was to describe the surgical treatment of a peri-implantitis lesion associated with a regenerative approach. A 48-year-old patient came to authors' attention 36 months after the placement of a dental implant (ITI-Bonefit Straumann, Waldenburg, Switzerland) in position 46. A swelling of the peri-implant soft tissues was observed, associated with bleeding on...

Abstract The limited options for bone repair have led to an extensive research of the field and development alloplastic xenogeneic grafts. purpose this study was evaluate with two substitutes: deproteinized bovine (DBB) biphasic calcium phosphate ceramic (BCP) in critical-size defect. A total 8-mm defects were made parietal bones rabbits (n=12). animals divided into three experimental groups: s...

Bone properties and response behavior after static or dynamic activation (loading) are still interesting topics in many fields of the science especially in the biomechanical problems such as bone loss of astronauts in space, osteoporosis, bone remodeling after fracture or remodeling after surgery (endoprosthesis and implants) and in osteointegration. This contribution deals with the relation be...
