Which of the following is not a part of the growth relativity hypothesis?
Growth relativity refers to growth that is relative to its displaced condyles from actively relocating fossae. John C Voudouris introduced this concept to explain the possible eﬀect of functional appliances on condyle and the resulting growth. The main foundations of growth relativity hypothesis  are:

Displacement of condyle.
Nonmuscular viscoelastic tissue stretch.
Force transduction beneath the ﬁbrocartilage of the glenoid fossa and condyle add new bone formation.
