Resolving differences between animal models for expedited orthodontic tooth movement

Understanding the differences between animal models and their adaptation biology as it relates to OTM is key to make valid conclusions. The rodent model can be used to understand the initial phases of tooth movement. Unlike the dog model, the rodent model does not lend itself to understand prolonged adaptation in response to bodily tooth movement. Extrapolation of rate of tooth movement to humans is more challenging from rodent model data.
