Wolff's Law dictates that the density of bone is dependent on its stress condition [7]. If the applied stress environment of a load-bearing bone region is decreased below its normal physiological levels, the bone density of that region can decrease leading to a reduction in strength, the degree of which is directly related to the stiffness of the implant material [8,9] .
Bone grafting plays a central role in craniofacial surgery, in both reconstructive and aesthetic realms. Bone grafts are used to fill bony defects, impart structural support, and augment deficient projection in the craniofacial skeleton. Although commonly thought of as a static entity, bone is in a state of dynamic equilibrium and has the ...
4 de oct. de 2018 · Wolff's law was proposed in 1892 by Julius Wolff, a German anatomist and surgeon, as a mathematical law that described the response of bone to mechanical loading. The mathematical aspects of his law do not fully describe the process of mechanically induced bone remodeling; however, the general process, often called bone functional adaptation ...
wolff定律骨力求达到一种最佳结构，即骨骼的形态与物质受个体活动水平的调控，使之足够承担力学负载，但并不增加代谢转运的负担。骨骼是活的东西，有其自身变化的规律。wolff定律指出：骨骼的生长会受到力学刺激影响而改变其结构。用之则强，废用则弱。
1 de sept. de 2009 · Abstract. According to “Wolff's Law”, bone is deposited and reinforced at areas of greatest stress. From a clinical perspective, this “law” is supported by the strong association between bone density and physical activity. From a mechanistic standpoint, however, the law presents a challenge to scientists seeking to understand how ...
1 de sept. de 2015 · Wolff’s law and mechanotransduction. Julius Wolff (1836–1902), a German anatomist and surgeon, theorized that bone will adapt to the repeated loads under which it is placed [ 2 ]. He proposed that, if load to a bone increases, remodeling will occur so that the bone is better equipped to resist such loads.
29 de oct. de 2019 · Wolff’s Law: Bone grows and strengthens under pressure (in proportion to mechanical stress) and weakens when it is rarely used. Our bones tell the story of ‘use it or lose it’ because the more physical activity we do, the denser and more mineralised our bones become. Runners have higher bone density in their legs and tennis players in ...
