Resorbable membranes are made of polytactic acid and will be resorbed in 4-6 weeks. Membranes are made in various shapes and sizes for different areas of the oral cavity. The surgical technique for guided tissue regeneration procedures is similar to that for bone grafts as far as flap design and root preparation are concerned. The membrane to be used is then sutured in the area using the crown of the tooth as anchorage as shown on the lingual furcation of the lower first molar. The flap is subsequently sutured over the membrane.
Postoperative care is similar to that described for bone graft cases.
This can be accomplished local anesthesia, sectioning of the suture and membrane removal with a pair of cotton pliers. Occasionally, it will require the elevation of a flap. Care should be taken so that no small segments of the membrane remain under the soft tissues. The two pictures compare the deep class II furcation invasion preoperatively a pocket depth of 2 mm 1 year following the surgical procedure. There have been reports which indicate that the combination of a graft material and guided tissue regeneration is the most predictable modality of treatment for clinical pocket depth reduction and bone fill of the defect.
