2. Conventional Orthodontics
 Pressure and tension in the PDL causes bone
resorption or deposition
 Rate of tooth movement is limited by bone
resorption

5. Biological Principles of AOO
 Regional Accelerated Phenomenon
 (RAP)
 􀂉 A large insult to bone (fracture, surgery) can
 initiate a localized “burst” of remodeling to
 repair the bone
Red = active bone resorption
Green = uncalcified osteoid
Gray = mineralized, mature
bone

6.  This remodeling induces Ca2+ release from
 adjacent trabecular bone, causing localized
 osteopenia
 􀂉 Osteopenia: Decreased calcification or
 density of bone
 􀂉 Osteopenia can be induced by surgically
 removing select portions of the alveolar cortex

7.  Osteopenia softens bone and allows for more
 rapid tooth movement by orthodontics
 􀂉 Dr. Kole introduced this to single-tooth
 orthodontics in 1959
 􀂉 Drs. Thomas and William Wilcko applied this to all
 the teeth desired to be moved (1995)

8. Selective decortication, followed by osteopenia
Remineralization begins 20-55 days after surgery
Orthodontic forces prolong remineralization (6
months?)
Complete recovery by 2 years
Bone grafts are used to increase bone height
and width
