Introduction
Residual ridge is a term used to describe the shape of
the clinical alveolar ridge after healing of bone and soft
tissues following tooth extraction.
Post tooth
extraction, a cascade of inflammatory reactions is
immediately activated, and the extraction socket is
temporarily sealed by blood clotting.
Epithelial tissues
begin its proliferation and migration within the first
week and the disrupted tissue integrity is quickly
restored.
Histologic evidence of active bone formation
in the bottom of the socket is seen as early as 2 weeks
after the extraction and the socket is progressively
filled with newly formed bone in about 6 months.
The
most striking feature of the extraction wound healing is
that even after the healing of wounds, the residual ridge
alveolar bone undergoes a lifelong catabolic
remodeling.
The size of the residual ridge is reduced
