lGrowth of the alveolar bone pushes the tooth
outward.
lContradictions:
lFibres run in a reverse direction than what the theory proposes
lNew bone cannot exert force on fibres already inserted into the bone
lIn Vit A and Vit D deficiency, there is increased alveolar bone or osteoid, but eruption rates
not increased
lWhen tooth with incompletely formed root is pinned to the bone, bone resorption takes place as
root grows
