Guided tissue regeneration

This concept is based on the assumption that periodontal ligament cells have the potential for regeneration of the attachment apparatus of the tooth.

Two types of barrier membranes have been used:

1. Degradable: Collagen, Polylactic acid, Vicryl (polyglactin 910) and Guidor membrane.
2. Nondegradable: They must be removed in three to six weeks time, e.g. Millipore, Teflon membrane, Goretex periodontal material.

Surgical procedure

1. Step 1: Raise a full thickness flap utilizing vertical incisions, extending a minimum of two teeth anteriorly and one tooth distally, to the tooth being treated.
2. Step 2: Debride the osseous defect and plane the root surfaces.
3. Step 3: Trim the membrane according to the size of the area being treated. The membrane should extend approximately beyond 2 to 3 mm on all the sides.
4. Step 4: Suture the membrane around the tooth with a sling suture.
5. Step 5: The flap is positioned back to its original position or slightly coronal to it and is sutured using interrupted sutures. Make sure the membrane is covered completely. In case of non-resorbable membrane, after 5 weeks of the operation, it must be removed with a gentle tug.
