Regenerative Therapy

This surgical procedure “regenerates” the previously lost gum and bone tissue. Most techniques utilize barriers or membranes, which are inserted over the bone defects. Some of these membranes are bio-absorbable (dissolve over time) and some require removal. Other regenerative procedures involve the use of bioactive gels.

The Biological Principle: Guided Tissue Regeneration

The biological principle of Guided Tissue Regeneration describes a race among four tissue types during healing:

  • Epithelium
  • Connective tissue
  • Bone that surrounds the tooth
  • Periodontal ligament

These four tissues compete for the space next to the tooth root following surgery. Without interference, epithelium usually wins the race and stops the bone healing.

        Before & After Regenerative Therapy


Some regenerative materials are designed to act as barriers to block the gum tissue. They are placed in order to isolate the space next to the root, so that the epithelium and connective tissue are kept away, thus allowing the slower growing ligament and bone cells to fill the space. Today, laboratory derived growth factors can be used in combination with membranes to help stimulate the re-growth of bone that has been lost to gum disease.

Guided tissue regeneration represents an enhancement to conventional therapy. Teeth can sometimes be saved that would otherwise be lost. Dr. Primm have done thousands of regenerative procedures using these barrier techniques.
