Accurate measurements of physical characteristics of bone are essential for diagnosis, assessment of change following treatment, and therefore, indirectly, for evaluation of new forms of therapy. This is particularly true of osteoporosis and aging skeleton, in which fractures occur easily. Methods: In this study an ultrasonic system was set-up and calibrated on Plexiglas tubes of variable thick...

Over the years, we have seen how, thanks to experimentation on animal models, foundations been laid in field of implantology. In most cases, studies related bone scale are carried out species that similar their movements and behavior humans. The femur has selected as reference for our test, selecting animals experiment with goat breed, bovine breed porcine similarity human body, obtaining speci...

considering the importance of bone augmentation prior to implant placement in order to obtain adequate bone quality and quantity, many studies have been conducted to evaluate different techniques and materials regarding new bone formation. in this study, we investigated the bone healing capacity of two different materials deproteinized bovine bone mineral (dbbm with the trade name of bio-oss) a...

The mineralized matrix of osseous tissue harbors abundant mitogenic activity which is extractable by demineralizing solvents. In bovine bone powder free of blood and cartilage contamination, the volume concentration of mitogens is up to 20 times greater than in serum. Growth factor activity in bone extracts was quantitated on quiescent mouse BALB/c/3T3 fibroblasts, where [3H]thymidine incorpora...

Paradoxically, bovine cartilage stimulates the immune system in resisting cancer and viruses, but suppresses it in rheumatoid diseases. Thus it acts as a “normaliser”. According to Dr. Pridden, “bovine cartilage closely resembles foetal mesenchyme, the primordial tissue from which muscle, bone, tendons, ligaments, skin, fat and bone marrow (the heart of the immune system) all develop.” “The car...

AIM Realize the surgery of sinus lifting floor to allow the installation of osseointegrated implants for oral rehabilitation, with the combination of different biomaterials, autogenous bone and lyophilized bovine bone. BACKGROUND Oral rehabilitation using the installation of osseointegrated implants is an alternative surgical approach that results in the satisfactory form, function and esthet...

In Japan, the most common articular disease is knee osteoarthritis. Among many treatment methodologies, tissue engineering and regenerative medicine have recently received a lot of attention. In this field, cells and scaffolds are important, both ex vivo and in vivo. From the viewpoint of effective treatment, in addition to histological features, the compatibility of mechanical properties is al...
