Bone Graft Substitutes

Bone graft substitutes in orthopedic applications have to fulfill various demanding requirements. Most calcium phosphate (CaP) bone graft substitutes are highly porous to achieve bone regeneration, but typically lack mechanical stability. This study presents a novel approach, in which a scaffold structure with appropriate properties for bone regeneration emerges from the space between specifically shaped granules. The granule types were tetrapods (TEPO) and pyramids (PYRA), which were compared to porous CaP granules (CALC) and morselized bone chips (BC). Bulk materials of the granules were mechanically loaded with a peak pressure of 4 MP; i.e., comparable to the load occurring behind an acetabular cup. Mechanical loading reduced the volume of CALC and BC considerably (89% and 85%, respectively), indicating a collapse of the macroporous structure. Volumes of TEPO and PYRA remained almost constant (94% and 98%, respectively). After loading, the porosity was highest for BC (46%), lowest for CALC (25%) and comparable for TEPO and PYRA (37%). The pore spaces of TEPO and PYRA were highly interconnected in a way that a virtual object with a diameter of 150 µm could access 34% of the TEPO volume and 36% of the PYRA volume. This study shows that a bulk of dense CaP granules in form of tetrapods and pyramids can create a scaffold structure with load capacities suitable for the regeneration of an acetabular bone defect.

Introduction: The global increase life expectancy and the resulting tooth loss has required searching for new rehabilitation alternatives in Dentistry. Biomaterials can be defined as any material that acts replacing a lost bone defect and its function. In Dentistry, many studies have aimed to improve bone regeneration through the use of BMPs for bone replacement. Objective: To review the literature on the use and clinical viability of human morphogenetic protein for the jaws reconstruction. Material and methods: The following databases were searched: Pubmed, Bireme, Lilacs, and Scielo and 30 articles published between 1965 and 2013 were found using the following descriptors: “dental implants”, “maxillary sinus”, and “biocompatible materials”. Results: Several studies demonstrate the biological advantages of rhBMP-2 on bone regeneration of the jaws. In recent years, morphogenetic protein has presented a large clinical use. Conclusion: Despite being a high-cost biomaterial, rhBMP-2 is a viable and very effective alternative for reconstruction of defects of the face.
