In the practice of Prosthodontics much attention is given to the preservation of residual ridge. Regardless of what material, technique or philosophy is used the fate of supportive bone is a major factor in the success of any denture. Bone continues to be a dynamic tissue that responds to its function. The extraction of teeth eliminates the need for alveolar process and bone is resorbed. However when tensile stress is received by bone, additional bone is formed. Such stresses occur when occlusal forces are transmitted to the alveolus by periodontal ligament. This later principle is used by Prosthodontists in an attempt to preserve bone.
