Biomaterials for bone regeneration
Objective: This article reviews the literature on biomaterials used for bone regeneration. Material and method: A total of seventeen bibliographic sources were found using the MEDLINE database and to avoid the variability of the search terms the thesaurus Mesh was used. Results: These materials act essentially due to their osteoconductive ability, although their osteoinductive capacity is being improved with the use of growth factors. As to their effectiveness, many differences exist between them and some even affect bone regeneration negatively. Conclusions: Biomaterials used for bone regeneration are valid when the correct material is used. As yet the osteogenic capacity of autogenous bon…
Evaluation of periimplant bone neoformation using different scanning electron microscope methods for measuring BIC. A dog study.
Objetives: The aim of this study was to determine which of three methods for measuring BIC (bone-to-implant contact), using vestibular and lingual scanning electron microscopy (SEM) for different implant systems at 15, 30 and 90 days post-surgery was the most precise. An elemental analysis with SEM was used to evaluate neoformed bone composition for three implant systems at the same study times. Material and Methods: 36 implants were placed in eighteen Beagle dogs mandible about one year old and weighing approximately 12-13 kg in order to evaluate bone apposition to three different implant surfaces. It was used the third and fourth premolar and first molar distal sockets in both quadrants o…
