What is Our General Understanding of the Rates of Tooth Movement?

  • Tooth movement is an inflammatory event and a reflection of the metabolic activity and healing capacity of an individual. Although we have no clinical means to measure that, we do know that tooth movement is most predictable and most rapid in pre-adolescents.

 

  • If we look at bone resorption overall, the limiting factor in determining the rate of tooth movement is actually the cell that we have been focusing on which is the osteoclast, and even then the specifics of osteoclast recruitment, mobility and activity are involved.

 

  • We look at bone porosity, the bone must be porous to allow access for osteoclasts and why we don't want an area of hyalinization as this would prevent the osteoclasts from going through and osteoclasts would have to work from the other side, from the marrow space side of the socket, instead of from the periodontal ligament side.

 

  • There's the remodelling and it's related to the number of osteoclasts, the osteoclast metabolic rate and, last, the ability to bring in new osteoclasts in the process of going from pre-osteoclast in the marrow, to recruiting them to the site and putting them to work as active osteoclasts.
