All these studies were based on extraction of whole collagen, not selection for fragments of particular molecular weight. Of the specimens in Table 1, only the three fish bones prepared at MPI-EVA yielded <1% collagen (0.8% in two cases and 0.9% in one). Given the fragility of fish bone...
Bone grafts and osteochondral grafts are performed in cases of severe tissue loss, non-union, and voids left after tumor resection. A major barrier to a successful bone allograft procedure is revascularization of the transplanted bone. Allogeneic bone is immunogenic, although the role of the immune...
At 1 week after tooth extraction the socket was occupied by a coagulum. The presence of osteoclasts on the inner surface of the socket walls indicated that www.intechopen.com Augmentation and Preservation of the Alveolar Process and Alveolar Ridge of Bone 145 the bundle bone was being resorbed....
three additional fragments were cleaned once for 10 min for further documentation with a digital microscope and ESEM (10–20.8; 10–20.9; 10–20.10). In this case, the control points were documented before and after cleaning (Table2). The aim of this additional step was to document possible ...
and microscopic porous structure that supports the formation and ingrowth of new bone at the implantation site [73]. A clinical study in humans in which porcine-derived graft was investigated for implant site development was showed to reduce the hard tissue resorption after tooth extraction [75]....
Bone collagen is an important material for radiocarbon, paleodietary, and paleoproteomic analyses, but it degrades over time, making such analyses more difficult with older material. Collagen preservation between and within archaeological sites is also v
600 °C. In relevant studies43,44, the water loss temperature of CMC was found to be approximately 80 °C. The decomposition temperature of the main chain fracture was approximately 260 °C, which released small molecular fragments; and the decomposition temperature was approximately 630...
Forensic anthropology includes, amongst other applications, the positive identification of unknown human skeletal remains. The first step in this process is an assessment of the biological profile, that is: sex, age, stature and ancestry. In forensic con
An open reduction of the mandible body fracture, tooth extraction of the alveolar bone fracture site and fragment removal was performed on a patient. Three months after surgery, the bone fragment was removed due to trismus and acute pain caused by the left condyle bone fragment. The removed ...
