Vital Statistics of Bone Remodeling

There are numerous texts and articles on the biology of tooth movement. An understanding of biology helps to answer questions such as "Why can't you change aligners every day?" and "How can I accelerate tooth movement" or "Why do teeth move at different rates between individuals".

Let's look at some vital statistics of bone remodelling:

• The lifespan of IBM (Basic Multicellular Unit) is 6-9 months
• Speed~25 um/day
• The lifespan of osteoblasts (active) 3 months 
• The lifespan of osteoclasts -2 weeks
• Rate of turnover of the whole skeleton
