 These patterns of tension and compression, are further proposed to result in patterns of bone resorption and deposition that lift the tooth into the mouth.This theory is based on Wolff's Law, which is the long established idea that bone changes shape in accordance with the forces applied.Significantly, a recent finite element analysis study, analysing the distribution of force through the jaw of an 8-year-old child, observed overall compression in the soft tissues above, and tension in the soft tissues below, unerupted teeth.
