Regenerative periodontal therapy encompasses a number of surgical procedures that aim specifically at gaining healing of periodontal destruction by developing new periodontium rather than by repair with a long junctional epithelial attachment. These techniques include:

• Guided tissue regeneration.
• Enamel matrix derivative (Straumann®, Emdogain).
• Bone grafts (Chapter 27).
• Growth factors.

Guided tissue regeneration

Following conventional flap surgery, cells from the overlying epithelium rapidly migrate apically. A long junctional epithelium results and this attaches onto the cleaned root surface resulting in healing by repair which does not mimic the original periodontal attachment.

Guided tissue regeneration (GTR) attempts to reorder the migration of cel/>
