5. AGE CHANGES OF MANDIBLE
1. MENTAL FORAMEN
2. RAMUS ANGLE
3. ALVEOLAR RIDGE
4. BLOOD SUPPLY

6. CHAMPY’S PRINCIPLE
1. Forces of mastication produce tensional
forces on upper border& forces of
compression on lower border.
2. Champy put forward the lines where plates
& screws have to be placed-” ideal
osteosynthesis lines”.
3. It corresponds to course of a line of tension
at base of the alveolar process
4. Only in symphysis region , 2 plates are
placed to neutralize

7. BLOOD SUPPLY
1.Helps in the healing
of fractured bone.
2.Endosteal blood
supply via inferior
dental artery &
veins.
3.Peripheral blood
Supply- Periosteum

8. NERVE SUPPLY
1. Inferior alveolar Nerve
2. Damage- angle & body
fracture
3. Anesthesia or
paresthesia of the Nerve
4. Recovery/ regeneration-
3 to 12 months.
