Bone is a composite material consisting principally of apatite mineral, collagen fibrils, non-collagenous proteins, and other organic species. Recent electron microscopy studies have shown that the mineral in bone occurs as stacks thin polycrystalline sheets (“mineral lamellae,” MLs) which surround lie between fibrils. We focus on effect interface these lamellae mechanical properties bone. Prev...
An important application of simulating wave propagation in bone is the early detection osteoporosis. During course this disease cortical reduced and replaced by marrow, weakening increasing likelihood fractures [1]. Commonly, modeling problem to only mechanical effects. Recent research includes electrical magnetic effects as well [2-4]. In our previous contributions we introduced a two-phase ma...
background. improving the implantation conditions in order to reduce the failure is always desirable for researchers. the aim of this study was to compare two different types of dental implant materials from biomechnical viewpoint in order to introduce a novel simulation method to select suitable materials for dental implants. methods. in this research, drilling process was performed in the cor...
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
Introduction: The temporomandibular joint (TMJ) is a synovial joint that has a fibrocartilaginous articular disc located between the articular cartilage of the articular eminence of the temporal bone and the mandibular condyle. As masticatory muscles maintain the integrity of the TMJ, the components of the TMJ are constantly compressed during occlusion. During mastication, muscle contractions a...
Disuse by bed rest, limb immobilization, or space flight causes rapid bone loss by arresting bone formation and accelerating bone resorption. Propranolol (a non-selective β-adrenergic antagonist) has been shown to improve bone properties by increasing bone formation and decreasing bone resorption in an ovariectomy-induced rat model. However, no studies have yet compared the osteoprotective prop...
Freeze-dried cortical bone can be used as a biological plate, either alone or in combination with other internal fixation devices, to stabilize fractures. In addition to it conferring mechanical stability, freeze-dried cortical bone may enhance fracture-healing and increase the bone stock. This study examined the effect of a freeze-dried allograft cortical bone plate (FACBP) on the biomechanica...
