Resistance of bone fracture. Bone strength depends upon bone structure. The denser the trabecular pattern, the stronger is the bone. This compressive strength of the vertebral bodies decrease with age.  

Initiation of bone formation around endosseous implants by pulsed electromagnetic fields. Must be performed within very early stages of healing, i.e., during the first and second weeks; after 2 weeks, no effect can be measured. This principle has only been used in animal studies.  

Device used to harvest bone particles through surface shavings for grafting purposes.  

Process of bone formation that occurs through the utilization of a scaffolding matrix that may deliver cells, genes, or proteins. The scaffold may be osteoinductive or osteoconductive and serves to maintain the architecture of the anatomic defect.  

Loss of bone due to osteoclastic activity. The gradual reduction of bone tissue is known as bone loss. The processes of bone resorption and new bone formation occur continuously. As individuals age, the rate of resorption surpasses that of new bone formation, resulting in a gradual thinning of the bone tissue. However, in certain conditions…

Any material other than autogenous bone, which is used as a hard tissue graft, in an attempt to stimulate new bone formation in an area where bone formerly existed.  

A group of osteoblasts and osteoclasts involved in bone remodeling.  

The turnover or replacement of packets of bone tissue called basic multicellular units, or BMUs, in all or part of a bone structure without a change in shape.  

Basic physiologic remodeling of bone takes place in a biologically coupled system of activation, resorption, and formation (ARF). Histomorphologically, the process starts in cortical bone as a cutting cone, consisting of a group of osteoclasts, digs a tunnel with a breakdown of 20 μm per day with a simultaneous increase in diameter of the tunnel…
