THE UNDERSTANDING THAT UNLOADED BONE CAUSE MORE BONE LOSS has brought an awareness towards replacing missing teeth and at the same time prevent bone loss.
WHY UNLOADED BONE CAUSE MORE BONE ATROPHY (BONE LOSS)???
MECHANOTRANSDUCTION
Solutions to the problem of atrophic alveolar bone begin with understanding why unloaded bone goes atrophic. Nobody can exactly depict why alveolar ridge goes atrophic after extraction of teeth. Efforts have been made to elucidate the scientific basis for the observation that the integrity of the skeletal tissue has something to do with mechanical usage. Frost has evolved the concept of the mechanostat (Frost, 1996) which he himself proposed as a new paradigm of understanding the mechanical-usage-dedicated message traffic routes between the skeletal tissue and the circumstances in which it is tuned. He argued the mechano-biologic negative feedback mechanisms would adjust skeletal architecture under the control of a subject’s mechanical usage.
Strain-derived fluid flow transduces the strain information to stimulate bone metabolism.
Skeletal tissue has its loading history by dynamic loading which is remembered as a microstrain.
If the strain is too small value, resorption dominates formation of bone tissue and the bone goes atrophic.
If the strain is adequate, resorption balances formation and the bone maintains its volume.
If the strain is adequately high value, formation at last dominates resorption and the bone goes hypertrophic.
If the strain value is high by the overloading outreaching the range of physiological limitation, the strain is accumulated in the bone tissue causing microdamage leading to fatigue failure.
Finally, if the strain value over the limit of yield strength the bone goes spontaneous fracture.

Due to these reasons immediate loading of dental implants will result in functional replacement of teeth and prevent any further bone loss.
