Proteína morfogenética ósea y su opción como tratamiento de la fisura alveolar

Int. j. morphol; 35 (1), 2017
La proteína morfogenética ósea (BMP), es una proteína endógena que ha mostrado efectos significativos en la promoción de la formación ósea. El uso de BMP ha sido descrito en la reconstrucción de defectos óseos de origen traumáticos y patológicos, incluyendo la fisura alveolar, el aumento de r...

Off-label use of rhBMP-2 as bone regeneration strategies in mandibular ameloblastoma unicystic

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT Jawbone reconstruction after tumor resection is one of the most challenging clinical tasks for maxillofacial surgeons. Osteogenic, osteoinductive, osteoconductive and non-antigenic properties of autogenous bone place this bone as the gold standard for solving problems of bone availability. Howev...

Collagen sponge and rhBMP-2 improve socket healing in rats treated with zoledronic acid

Abstract The aim of the present study was to evaluate the possible use of a commercial absorbed collagen sponge and bone morphogenetic protein (BMP) for the prevention of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in rats. Twenty rats received intraperitoneal injections of 0.1-mg/kg of zoled...

Diabetes mellitus affects the biomechanical function of the callus and the expression of TGF-beta1 and BMP2 in an early stage of fracture healing

Braz. j. med. biol. res; 49 (1), 2016
Transforming growth factor beta 1 (TGF-β1) and bone morphogenetic protein-2 (BMP-2) are important regulators of bone repair and regeneration. In this study, we examined whether TGF-β1 and BMP-2 expressions were delayed during bone healing in type 1 diabetes mellitus. Tibial fractures were creat...

Medium modification with bone morphogenetic protein 2 addition for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether medium modification improves the odontogenic differentiation of human dental pulp stem cells (DPSC) in vitro and in vivo. DPSC isolated from human impacted third molar teeth were analysed for clusters of differentiation with flow cytometry. Odontogen...

Maxillary Reconstruction Using rhBMP-2 and Titanium Mesh: Technical Note About the Use of Stereolithographic Model

Maxillary reconstruction is a common procedure in maxillofacial surgery; for this purpose is used autogenous bone, alloplastic bone or another one with different results. In all of them, traditionally the use of computed tomography is used to make the surgical plan, however, 3D models are not used freque...

Sox2 function as a negative regulator to control HAMP expression

Biol. Res; 48 (), 2015
BACKGROUND: Hepcidin, encoding by HAMP gene, is the pivotal regulator of iron metabolism, controlling the systemic absorption and transportation of irons from intracellular stores. Abnormal levels of HAMP expression alter plasma iron parameters and lead to iron metabolism disorders. Therefore,itis animpo...

Biochemical Analysis by Calcium Determination on the Newly Formed Bone in Critical Bone Defects Submitted to Different Treatments: A Pilot Study

Int. j. morphol; 25 (3), 2007
The aim of this study was to evaluate the calcium dosage of the newly formed bone, in critical bone defects created on the calvarial tissue and filled by different substances, in male Wistar rats. A cylindrical critical bone defect (6x2mm) was created in the posterior portion, left side, on the calvarial...

Osteoinductive Potential of the rhBMP-2 in Soft Tissues

Int. j. morphol; 25 (1), 2007
The rhBMP-2 is an osteoinductive protein used in the reconstructive with the objective to create newly formed bone. The aim of this study was to confirm the rhBMP-2 osteoinductive capability, when implanted in soft tissues. The results showed that the protein used in this study is highly osteoinductive....
