Guided Tissue Regeneration

Guided tissue regeneration is one treatment strategy to treat bone loss associated with periodontal disease.  This technique is most effective for vertical bone loss.

Guided tissue generation is not a casual procedure.  The Consil must be properly placed and the flap must appropriately adapt to the tooth.  The flap must be well vascularized in all cases.  An intermediate material is sometimes selected to cover the Consil underlying the flap.
Case selection is very important.  If the patient has an oronasal fistula, the Consil will migrate into the respiratory tract and act as an irritant.
